Initial thoughts on my new LTD

Shambler

New member
Two weeks ago I found myself at a park with some members of our local club, and my Explorer battery was dead. I pulled out my F75-Lite and started hunting like I've done many times. A couple of the Explorer users started calling me over to check targets since they have consider buying the F75 on ergonomics alone. Most of the targets I was shown, I had to admit I wouldn't dig because they were just a chirp (and there were TONS of chirps at this park), but there was one target that finally got me angry enough to start looking for an LTD. A fine detectorists using an old XS called me over to hear what he described as definite deep silver. I heard NOTHING... 99 sens, 0 disc, 3 tone, DE mode .... nada, zip, every direction TOTAL SILENCE. Well, out came a barber dime stuck to an Indian at about 9". I couldn't believe it. I've found things in parks, but I normally use my Explorer II because I feel in parks, it's just easier to use and so much hotter on silver. I never dreamed it could be THAT MUCH BETTER! I've found lots of stuff with the F75, but it just wasn't going to work as a backup knowing I could miss a great find like that (right or wrong - I'd finally lost complete confidence in it).

I bought an LTD (in an incredibly smooth transaction from the Findmall classifieds :clap:).

My initial thoughts:

  • BP mode is QUIETER than DE even at zero disc and high sens. I don't know how they did it, but it's a very good thing!
  • The park depth issue is gone. In BP mode, at 80 sensitivity, I was digging very deep small targets and could hear all targets that were first found with an Explorer.
  • It has the same ergonomics and weight. Best I've ever hunted with in that department.
  • When in BP the TID is HORRIBLE. Instead of bouncing between 4 or 5 numbers, its bouncing between 20 or more numbers. I'm not sure there's a pattern to it either. A clad dime at 5" can be anywere from 30 to 90 with every pass giving a differnt number. Even wadded up foil would give high numbers/tones on most passes.
  • BP mode increased my iron falses.

If Fisher stays with the F75 platform, they might want to consider some type of circuit that averages the numbers after X number of passes and settles them down to something more realistic. I spent the first part of today digging everything because I had no idea what the detector was telling me. Everytime my hunting buddy called me over to listen to what he believed was a good target, I could definitely hear the target, but I had no idea what it was. In the woods or fields, this thing will be a beast, but I still think it's underperforming the Explorer on manicured lawn when you're looking for deep silver amongst trash. Today, when I went back to my Explorer, I dug 3 silver dimes, 8 wheats, and a ring all the while digging about half the holes that I was with the LTD.

You guys that have used the LTD for a few months see a TID pattern yet, or are you in fields and forests looking for relics where TID is largely unimportant?
 
I don't see as big of a spread on the TID in BP mode as your reporting, but I agree they have some work to do tightening the TID (if my F4 can have an accurate TID, why not the flagship F75 LTD :shrug:
 
Not being there I can only give you a educated guess. Increase your sweep speed when your having trouble locking into better target ID's, trying to keep the sweep the width of your shoulders. Try not to do the Minelab wiggle with it.

There was at one time, a mention of this in the F75 owners manual. Anougher thing that made me think your sweep speed may be too slow, is your too familiar with the Explorer. One likes a slow sweep speed to ID correctly, and the other is a faster unit.

It's just something to try that you may not have thought of. Nothing to loose, plenty to gain. :thumbup:

The TID problem is most likely due to the F-75's operating frequency. Apply the new processes to a detector that operates at a lower frequency and I'd bet things would tighten up considerably. The Omega at 7.8 Khz for the most part gives nice tight readings on coins near max disc depth. The deeper dimes I have dug with it were 'no-brainers'.

You just can't do this in a trashy park. Most non-trashy parts of parks were cleaned out of quality finds 20 years ago. Now they're all deep or partially-masked.

There's even a video posted by a Fisher junkie that has an Indian head jumping on tons of numbers between 25 and 80.

Fisher went in the right direction to making this an "all around" unit instead of, in my opinion, mostly a relic hunter. Maybe after more hours of use, things will become more clear. I'll be sure to report :)
 
I have been using the 5" coil a lot, so I am ultimately able to really zero in on the target and am not seeing the numbers spread as you are. I do know, though, my LTD does not lock on targets like my F 75 does and all coin numbers also read 3-4 numbers higher on my LTD then my regular F 75. That is not a serious problem, but it has taken me a while to get used to, but am about at the point of being able to call the target far more often then not. Over all, the LTD is different then the F 75. A lot of it for the good, but it has taken some getting used to. HH jim tn
 
Shambler, I have to agree with you, I took my LTD out this morning in the middle of nowhere and could run it wide open 95-sens 0 disc in BP mode and it was quiet as could be. I found 10 shotgun shell tops and 3 - 22cal lead pieces among other stuff. But the TID was all over the place on these targets. You would think the lead would read about the same but it was all over the place and the same with the shotgun shell tops. The LTD will definitely find it but it is harder than the F75 to tell what you have found. It was nice to be able to run the LTD wide open with no fatigue, I think it is a killer relic machine, just wish the TID was better.

I certainly don't disagree with ya.

On the Fisher junkie's test you mentioned, are you referring to Bill Ladds video above. He was making a video, and wasn't concerned about a close accurate ID reading. You will notice he's doing real little sweeps over the target with the coil. He was also running at real high sensitivity. Drop Bill a note, he'll fill you in about that. If you take a look at your F75 manual it explains it better than I can.


Like I said I wasn't there with you, and only you know what it was like for you under those conditions.

Was you using a smaller coil ?

I wish you luck in your silver hunting ventures. May you find plenty, no matter what way you use. :)

Mr. Bill
 
I will see the number repeat and then I can guess what I may have and dig it....
 
is the vid good and tight on the omega 8000?..not much jumping around?
if so,then yes you pretty much CAN tell what ya got most of the time!
the more i read about this detector the more impressed i become!

(h.h!)

Jim what kind of depth are you getting from that 5" DD compared to the 11" DD ?

That little coil should be killer in trash, but it feels like your painting a 747 with a Qtip :wacko:

As some folks are not reporting the bouncing TID #'s, and some are, I wonder if:

(a) those that aren't have their machine setup in a manor that contributes to it's stability better, and/or
(b) if the folks with the jumpy TID #'s have higher then average mineralized ground, and we could validate this using the fe304?
 
the 5" coil doesn't cover much ground, but using it has prompted me to just inch my way along and when I get any kind of a high tone, chirp, weak, strong, whatever, in 3h tone I've learned to check it out carefully. I have said it before, but for me it has been a killer coil making finds that I repeatedly missed with the regular F 75's stock 11" coil and then the smaller 6 1/2" elliptical.

As far as depth, it hits 6-7" coins with ease and I have dug a couple at a true 9." While 6-7" coins are easily hit, the tone seems to weaken pretty quickly after that.

Ground here is light to medium mineralization. Feo usually reads 0.03 to 0.1 and fast grap g/b is low to mid 60's as the norm.

Thanks Jim. I have a pretty good spot to work this coil on. I'm looking forward to seeing it work it's magic in BP mode with heavy trash :thumbup:
 
You just have to work an area with the small coil take you time keep coming back clean the trash and hunt some more. If you find anything that is a relic or old coin work if from different directions. Try AM on the small coil in boost mode drop your disc from 6,5,4. It took me a year working an area near my house with the small coil the get handful of history that no one else could find. Sometimes we have a one time in to a hunting spot so you have to be lucky and find the hot spot. Almost every place I have hunted seems to have a hot spot and you just work it all day even for a few goodies. Once I had a guy tell me that I would never find anything on the one old house. He said it had been worked with every detector out there for years. I worked it for about two months on and off and pulled out a nice late 1800 V nickel and large cent and a show buckle and a barber. They were being somewhat maksed by iron and trash and it was the small DD that helped me and the hits were real bad sounding even in mono tone.
