Impact's Maiden Voyage....Mixed Feelings.
Posted by: CousinEddie
Date: October 14, 2017 06:39PM
My Impact arrived yesterday. I am very impressed with it's sturdy build and many useful features. I took it out for it's maiden voyage today and have mixed feelings. I went to a few sites that I haven't been to in a few years because I wasn't finding anything with my other machines. Basically testing it's depth to see what I missed. I have to say, the air tests are amazing. I am air testing quarters at well over a foot. Now I know air tests aren't accurate, but it is impressive. So I hunted in DI2, Deep, and VLX1, in all 3 frequencies (5, 14, 20). My soil where I hunt in SE Pennsylvania can range from mild to heavily mineralized. The sites I went to tonight were in the moderate to heavy mineralization category. Except for my F75, my other machines run pretty quiet at these sites (T2, AT Gold). The Impact is a chatter hound, just like my F75. I didn't have the gain cranked, but you would think I had it maxed. I was running it between 80-86. It was very rough on the ears. As for depth, I didn't find anything super deep. Doesn't really concern me as there probably isn't much super deep stuff at these sites. What does concern me is that I wasn't able to hit a quarter at 7 inches that I buried 2 days ago. I tested it when I got home and it makes me wonder if there is something wrong with the machine and I was missing deep stuff at those sites. I'll keep working with it until I learn it, but I was definitely surprised at that lack of ability to hit a 7 inch quarter. BTW, I was grounding balancing in the low-mid 60's at each site.

VLX1 was the most stable. Looking forward to future hunts and hoping this machine can deliver, considering it's claim of being amazing.

Use disc instead of tone break and it will really quiet it down. You are also able to increase increase gain then.

Try di2, disc 5 or higher, gain 94-98, iron vol. 1 or 2, 14khz. This purrs along nicely.

Something is not quiet right there.I found a flake of steel 0.1 gram at 4 inches deep in GEN mode and 20 Khz.Too low a tone break setting can mask both iron and gold in the discriminate modes.

The first day out should be considered a learning experience, don't expect to figure it out in a few short hours. Bench testing is not the same as a real world hunt.
You won't start to see the Impacts true capabilities until you put in at least 20 hours learning, took me about a month to really start getting the hang of it. Every time out now I see new things it can do and understand why and how it does it.
I haven't even begun to try out different tone breaks, tone frequency, etc. Think I am just about there to try and tinker with some other settings. The learning curve is much shorter than a Minelab Safari, Explorer.

Shift of frequencies within a frequency can make a difference in quieting down the Impact. You may also want to hunt in Di3, Di99 mode and lower the iron volume..raise the disc like on the T2 to about 18 where foil starts. Or higher 24 where thin gold rings will still sound off.

Some detectors are not deep on freshly buried coins at 7", but do much better when the coin has been buried for a long time. I found a penny at a true 9" with the 5x9 coil. That was the first day learning the detector. Almost past up on the target, something said dig. Think it was just a brief deep sounding high tone squeek.

I leave the tone break at it's default in each setting. I was finding stuff, just nit super deep. Again, these sites I went to were heavily pounded. The Impact won't make it appear if it isn't there to begin with. I have used many different machines over the years, it doesn't seem like there is a problem with the machine....most likely user error.

How am I able to determine what tone break is best for each mode? I didn't know audio tone could affect the signal and depth.

Setting your tone breaks will depend on your targets of interest, coin denominations.

I don't think audio tone affects depth.
Now depending on one hearing different tone setup could maybe affect.

Also, depending on the mode you are using, and if you have Vdi normalization selected or not, these will drive your tone break settings too.

I am mainly hunt Colonial era sites. Lots of iron and fertilizers in the ground at these sites. Even though the ground balance shows 60's, the machine pops and clicks like crazy. I hunt for coins and relics. I lean more towards relic hunting.

Congratulations on now owning what is quite possibly the best general-purpose detector on the market.

Okay, okay ... I know I am rather biased since I am very partial to the Nokta FORS CoRe, FORS Relic and Impact models, but it is for the very good reason that all of them have been providing me not just successful, but exceptional in-the-field performance.

Let's see ... you now have had your Impact since October 13th, so if you have favorable weather and detecting conditions, and have the opportunity to get out and put in the time and effort to learn it well, you ought to have a good feel for the Impact and what it can provide by Christmas. That would give you a good 2½ months which should be needed to get a really good 'feel' for the Impact and determine some adjustment settings for the different modes that might work for you and your hunting needs. Also time to figure out if there's an additional search coil to put on a last minute Christmas Wish List.

You are correct, that 'air tests' can be useful for some things but we can't always expect to duplicate their performance when ground mineralization and unseen masking targets are in the mix.

Does this site have very much trash? If it is trashy, that can certainly impair a detector's ability to hit on deeper-located targets due to target masking by shallower and nearby junk.

So I hunted in DI2, Deep, and VLX1, in all 3 frequencies (5, 14, 20).
Which make/model detector(s) have you been using most often recently, and did they offer similar Tone ID options/modes? You didn't mentioned various settings, but trying to check out the new Impact on your first day, and experimenting with three different modes and working them each at three different frequencies could easily be cause to end up a little confused. Give it time and don't rush too quickly through the different search modes. If you had been using a Nokta FORS or Makro Racer series models first that might have helped a little at understanding how their devices work, but now you're going to need a little time to get to know the Impact. It's likely to be one of the 'best friends' you ever had.

My soil where I hunt in SE Pennsylvania can range from mild to heavily mineralized. ... BTW, I was grounding balancing in the low-mid 60's at each site.
I've hunted some sites that have a GB in the '62' to '68' range and it was wonderful, but also some with the same GB phase range that were more of a struggle. They had a bit higher MMI read-out. I have also hunted many places with a ground phase anywhere from '74' to '81' but didn't experience too much problems. They had low to mid-level MMI read-outs, and they were also free of a lot of trash, including now annoying small shards of rusty tin densely scattered about.

I have owned two F75's and a half-dozen Teknetic's T2's, of which I favored the T2 ... but only with the small, round 5" DD coil when Relic Hunting very dense debris.

I have handily working my Nokta FORS CoRe and Relic in the same sites, side-by-side with a T2 and F75, and always had quieter and smoother operation, and the same goes for the Impact. A lot will depend on the operating frequency, the Gain setting, the Discriminate setting and the search coil that is in use. With comparable adjustment settings, I'll grab any of my Nokta models that are still on-hand.

CousinEddie
As for depth, I didn't find anything super deep. Doesn't really concern me as there probably isn't much super deep stuff at these sites. What does concern me is that I wasn't able to hit a quarter at 7 inches that I buried 2 days ago.
More often-than-not, a detector can achieve a little better depth-of-detection on a longer buried object in undisturbed ground than a freshly positioned similar object in recently disturbed ground, so that result isn't earth shattering to hear. Also, detection depth is going to be determined by the absence of any nearby or shallower masking objects, by the search coil used, and also the search mode, the combined settings, and the search coil sweep speed presentation.

One planted target in freshly disturbed ground in one specific location shouldn't be a decision maker. Did you compare other makes and models and coils at the same time you checked that target with the Impact? Which coil were you using on the Impact, and, by the way, what search coils do you have other than the standard 7X11 DD?

The Impact IS amazing and it will deliver. Again, the proper search coil might be needed for challenging site conditions to get the best out of it. Also keep in mind that there is no such thing as a 'perfect' metal detector, leaving us to pick-and-choose from what is on the market to find the one, or several, that seem to fit our wants and needs. For me, that includes the Impact, Relic and CoRe models.

Yes, the Audio Tone pitch can have an effect on us hearing a target response, and that means we might not find deeper targets that out personal hearing can't discern.

Tone Break can be adjusted by the consumer based upon where they live and/or what type of hunting they like to do, allowing the user to set break=-pontes based upon the typical targets they anticipate finding. For example, here in the USA I am going to regulate the Tone Break settings to be most appropriate for each search mode based upon the conductivity of commonly-found USA coins.

Be sure you don't confuse Tone Break with Audio Tone settings as both do different things.

I mainly Relic Hunt, but working the older sites and their periods of activity I do have a great interest in finding older era US coins, Trade Tokens, and other smaller-size artifacts like bullets, cartridge cases, metal buttons, clothing fasteners and military adornment.

On occasion I do have to deal with man-distributed fertilizers and such, but seldom get to hunt ground with a GB phase read-put less than '78' with most being from that up to '86+' as well as an ample amount of sheet iron and other ferrous trash.

In a vehicle break-on and theft last Sunday night to Monday morning, five of my Nokta detectors were stolen along with two back-pack detector bags with accessories. Unfortunately, with all the coils I had for my two Nokta impact devices, I was left with only the larger 14X15 DD which was still at home, and the 5X9½ DD that was attached tom my other Impact that was at my oldest son's shop. he had one of my Impact, one Relic and one CoRe as he was making a padded wooden detector transport box for me that we had designed, but my other Impact, 2-Relics and my other CoRe were along.

When I am able to replace all of the missing detectors, coils and bags, I'll be at ease because smaller coils are very important to me, and the Impact they stole had the excellent 7" Concentric coil mounted. That, and the now gone 5" DD, have been my two most used coils on the Impact, followed by the 5X9½ which is the only coil I have left for day-to-day detecting for a while.

I say this only to stress the importance of search coil selection and I hope you have more than only the standard 7X11 for your Impact.

Thank you for all the info Monte. I love it when someone takes the time to give a thorough reply. So, I took the Impact out again today to a farm field that I haven't hunted in a very long time. I hunted this field with a safari, F75, T2 SE/T2 Classic, F70, AT Gold, and Vaquero. I stopped finding stuff a while ago. I had a better day with the Impact and learned a little of how the machines handles. Like my F75, it is a very sensitive machine...even in the lower gain settings (mid-high 70's). I ran it today in DI2, 14 khz, gain 86-94, disc 12, audio 22-25, tone break 20. Ground balance ranged 48-63 in different areas. It still popped and clicked as it went through more mineralized areas, but that is something that all my machines did at this site. The grass was still high so I was swinging about 3 inches off the ground in most spots. I gotta' tell...this machine found some decent targets the other machines missed. The targets ranged in the 7-10 range, but remember, I was swinging the coil off the ground about 3 inches due to the high grass. So it was hitting them at very respectable depths when you add in the grass height. I found a deep wheatie, suspender buckle from late 1800-early 1900's, flat button, and a pewter spoon piece. All were great signals. At least I know it was user error yesterday and not the machine.

As for now I only have the 7 x 11 coils. I will be purchasing other coils in the future. I really like the machine and without a doubt I will be killing out there very soon. Thank you for the advice everyone!

Monte-"Congratulations in owning possibly one of the best all round detectors."

I think one of the reasons your statement is true is that the Impact can easily be used in Australia,s Golden Triangle Goldfields where we have the highest mineralisation levels in Australia. The Impact can handle very high mineralisation in GEN mode and DEEP mode also,my prefered two modes for gold prospecting.GEN mode is very good for small shallow gold whilst DEEP is very good for larger deeper gold. Although the Nokta manual does not recommend using DEEP mode above medium mineralisation, it has been my experience it is slightly chatty but not as hard on the ears as the GEN mode constant threshold. All the propaganda by Minelab owners that Impact is just another VLF is not true. PI,s can still outperform it in the depth department because their depth capabilities are not affected so much as a VLF by very high mineralisation. The reason I use the Impact is it can easily discriminate out the many hot rocks (actually smaller stones} that we have here.

Congratulations. That was a great hunt. I have mild ground so I want the 7" concentric coil. Monte will know if that coil works ok in mineralized ground or not.
Concentric coils usually don't work as well as dd coils. The 7x11 is great coil and depth is incredible. I don't know what other coils you should have. I also wouldn't mind having the Nel Snake coil but I don't think they are available for this detector. I'm not that happy with the 4x7 coil. It hasn't performed good enough for me. If you hunt in a lot of iron trash that may be your only choice.

Thank you for the kind comments. I bought my first computer, a Packard Bell, in '96 I believe so that I could have the word processing abilities over an old fashioned typewriter to work on my book. At least that was my initial idea. With this new 'Internet' stuff going on I thought I'd check in on any discussions about metal detectors and I found one or two websites that had some interesting discussion Forums, but reading some of the comments by newcomers to this great sport, I also read replies that seemed to also be offered up by newcomers as well. Folks who lacked ample field time with detectors, or use of a variety of makes and models, or learning about the available adjustment features and working in really challenging ground.

Quite often I would read a reply, but noted that is was an exact, or very slightly altered clip or quote from a metal detecting book/publication, or just a very familiar long-time quote that we have typically heard in this industry going back decades before the Internet and spouted by anyone, to include things we'd read in manufacturers ad slicks and such.

So, I thought I would try to help explain a few things or help answer questions, from typical stuff to more complex .... and that's brought me to where I spend a lot of time today, 21 years later, reading and posting on only a few favorite Forum sites. And I only do it to try and help get answers correct for folks or do something in some way to help improve their understanding of detecting or specific detector so that they might enjoy success afield and keep active in this great outdoor sport as I have for over 52½ years now. It does brighten my day when someone shares a 'Thank You' with me.

I always enjoy re-hunting a site. It can be going back the next day or anytime in the future to a place that I have spent some dedicated detecting time. It could even be walking behind someone as they work a pathway down an area, or stepping in to re-search a gridded space once someone has concluded it is 'worked-out' or void of anything good.

I have quite a few favorite sites on my list to evaluate detectors and coils at that range from two old picnic groves to eight city parks and eight totally ghosted old town sites. My long-time favorite is "Twin Flats" Utah which I have hunted since May of 1969 with at least 95% of all the better-suited detectors I have ever owned. It was very weeded up this year and I never had the opportunity to hunt it with anything, to include the Impact, but it is on my list for few-day detecting jaunt as soon as early spring of 2018 gets here. I hope to catch it weed-free and work the Impact for a few days while relaxing, now that I have a comfy camp trailer to enjoy some time and get rested up for a fresh days afield w/o extra driving..

Great, and that's what is needed. With all the Impact has to offer, I think it's best to just work with one search mode at a time and concentrate on learning the impact, slowly tweaking the various adjustment features as needed to find some settings for that search mode that are what you feel will work best for you and the types of sites you like to hunt. Once confident, move on to the next search mode. You'll already have some idea of the settings that might work by then to start with and do a little tweaking ahead of time based upon what you then have learned. Then polish up the adjustments for the different behavior the various search modes provide.


Quote
CousinEddie
Like my F75, it is a very sensitive machine...even in the lower gain settings (mid-high 70's).
Don't hesitate to adjust the Gain a bit lower if you feel the need to reduce EMI or just hunt in closer to some interfering metal structure or fence, etc. All of my 'turn-on' settings for each mode have the Gain at '85' or '95' except Di3 which starts-up at '99.' I can then adjust them lower and reduce the gain should I want to or need to. I usually don't, or not too much when I do, but there are times I have run the Impact (or other Nokta models in my arsenal) as low as '25' to '40.'


Quote
CousinEddie
I ran it today in DI2, 14 khz, gain 86-94, disc 12, audio 22-25, tone break 20.
My Impact Di2 saved settings are:
'95' Gain
'03' Disc.
'02' Fe Volume
'15' Tone Break
'15' and '50' Audio Tones
'01' i-SAT

I usually set my Tone break for each mode at the Ferrous / Non-Ferrous break-point, thus '15' for Di2.

I then set my Disc. at a point where Iron Nails are just accepted, at '03' the Impact (the same as the Makro Racer 2), as that lets me hear Iron nails and some more-conductive ferrous trash. I then use a Ferrous Volume setting of '02' to keep the loudness of Iron responses (from targets above the Disc. level of '03' and below the Tone Break setting of '15') 'hearable' but quieter. That way I know I am in ferrous trash and that could mask a good target so it alerts me to make sure I am using a more controlled and slower sweep to work in and around the iron debris in hopes of hearing a response form a more conductive target to recover.

You will find me hunting iron littered sites more often than not, and since I like to listen for typical iron debris I have my Disc set low enough to just barely accept Iron Nails. With the Impact, I will bump my Disc. up to '05' if-and-when the density of nails gets too annoying and I want to just barely reject most common nails.

As for hunting in very dense trash, I prefer to use a smaller-size search coils and my start-up is in Di3. I found the Three-Tone modes with the processed audio to do a great job of dealing with problem iron trash, and the biggest ferrous problem for me is sheet iron, more commonly noticed as rusty tin. It still does well with nails and other iron, but smaller coils and dense junk call for Di3 for me, at least to start with.

When I hunt sites that have more space between unwanted targets, then I opt for a mid-sized search coil, my favorite being the 5X9½ open-frame DD. It works well for 'cruising' low-to-modest trashy open areas, and in those cases I also like to use Di2 a lot or even the GEN mode. In really nasty conditions with very closely located trash, especially iron, my preferred search coil is the solid 5" DD. If not too bad, or if very little iron in the mix, the 4X7½ elliptical DD is a handy coil, but it doesn't match the 5" for really challenging conditions. Again, I use Di3 with either of these coils in such environments.

My now-favorite general purpose coil for the Impact is the new, and excellent, open-frame 7" Concentric coil.:thumbup: It was, and maybe still is, mounted to my main-use Impact that was stolen a week ago. That is the #1 coil I need to replace in my coil inventory, and the round 5" DD is a very close #2 position. The 7" Concentric is terrific for everyday Coin & Jewelry Hunting, and so far it has been performing great in the iron littered ghost towns I have been hunting. Dense iron trash, especially a lot of concentrated rusty tin shards, and old square nails of a wide range of sizes.

With the 7" Concentric I am comfortable using it in any search mode and often will cover a dedicated area in Di3, switching to rescan some of it in GEN or Di2.

When you have a lower GB requirement it suggests the ground might not have much iron of other 'bad ground' to deal with. If that's the case, then any detector might seem a little noisier or sparkier at times simply because the circuitry isn't having to process out challenging ground mineral signals. I can be controlled with gain settings or other adjustment functions, and also by using a smaller-size coil which sees less ground and is less apt to be bothered by nearby EMI sources.

The targets ranged in the 7-10 range, but remember, I was swinging the coil off the ground about 3 inches due to the high grass. So it was hitting them at very respectable depths when you add in the grass height.
Working the search coil 3" off the ground, with 'ground' being dirt or pea gravel or rocks or sand, whatever the solid substance is, isn't too far off the mark for where a search coil ought to be worked. Most manufacturers who write a well prepared User Manual will note, or should note, that best performance is achieved by working a search coil ±2" above the dirt (or whatever solid surface there is). If a coil is too close to the ground you can impair performance because that will often warp the EMF which could cause overloading, or simply degrade the performance, especially for detection depth.

Note in the Impact's User Manual on Page 5, upper right-hand sketch and comments below. Also read #13 on Page 6. This is often overlooked in any detector manual, and too often I see people 'scrubbing' their search coil of cruising way too close to the ground surface. Something that is definitely not in their best interest with our modern detectors of the past thirty-five years or so that rely a well engineered motion-based Discriminate search mode.

My 15 kHz FORS CoRe usually gets slightly better depth-of-detection than my 19 kHz FORS Relic, and both have performed quite well against any of the competition, be it a conventional VLF detector or something in the BBS or FBS design. The Impact, however, working at the turn-on 14 kHz and using a comparable size search coil, usually edges out my other favorites by just a bit of detection depth. It really is a deep-seeking detector when properly adjusted and used with an efficient coil sweep presentation.

Well, as you continue to learn the Impact, be prepared to learn how well some of the accessory coils might help out. Now, picking out an optional search coil or two can be a real challenge with what Nokta offers in coil selection. :unsure:

Other than my 14X15 I had at home on a spare lower rod, and the 5X9½ open-frame DD I had mounted on my 2nd Impact that was at my son's shop, ALL of my other Impact search coils were stolen last week. I had all of them, plus a brand new Nokta Pointer in the hard case, carried in my Impact back-pack detector bag which they took, so I started wondering which coils I wanted to replace. I came to an easy conclusion, and that is I want to replace ALL of the search coils. Next I had to figure out which coils I used the most or would want to use the most as I start to shop to rebuild my Regular-Use Detector Team. My favorite coils are listed as follows in order of need or preference:

7" Concentric open-frame
5" DD solid
5X9½ DD open-frame This one I still have.
4X7½" DD solid
7X11 DD standard

My suggestions so far, to anyone looking for an accessory coil for their Impact, is in this above order.

Looking forward to your future posts with comments about coming along with the Impact as well as the finds you will be making. I hope the weather holds out for several more weeks up where you live so you can enjoy more time out hunting. So far, it is getting colder at night but still pleasant and huntable during the day here is far Eastern Oregon, but if we get some really terrible weather like our record-setting winter of '16-'17, I'll hook up my trailer and make a couple of weeks with a brief 'snowbird' run somewhere to the south to be sure t0o get some swing-time in.
