I'm about to bite the bullet and buy a impact,being a Garrett user i think its time for a change and withe all the new VLFS hitting the market the impact relay catches my attention,I like the way nokta listen to our needs in detecting and come good with suggestions ,this is a huge leap in customer confidence,can someone tell me is the all metal mode a true all metal or is it a mixed mode. I will buy the pro pack as i think its the best way to go and i will be landing in Portland from Australia mid august but cant find a nokta dealer in that area so some help there would be appreciate, happy hunting and good luck Bazza :thumbup:

Tigermoth,
Yes, there is a true all metal mode (Gen). It can be used in conjunction with iSAT in heavy mineralization and disc too if you like. This mode is a very capable nugget hunting mode.

The Nokta dealer out in the Western US is Arizona Outback in Prescott Valley, Az. Give Chris a call .

Thanks Dean Ive had trouble finding an answer to the all metal question, I think this detector will do the job around some old mining camps where they camped on the gold but left their Ferris metal scattered all over, cheers Bazza

I hunt the old mining camps here in Arizona and it works like a charm. It has a mode for every need.
Best of luck!

I believe, but I do not have the Impact at this time so I'm not sure, but I think there are several All Metal modes and one of the All Metal modes actually offers discrimination.
As Dean has said it's a pretty unique machine offering many different ways in which to set it up.

Also in Gen mode you can pull the trigger in pinpoint and use the arrow keys to increase the volume. I set mine to 5 max. My tests in my mild ground, Gen mode has the best separation and depth. Deepest mode in my ground. I like this mode but still the good hits are quiet. I would like the good hits louder. Runs smooth at sens. 99. Seems immune to emi.

Dbado1. Your comment about nugget hunting with the Impact is the first I have seen on any forum or Youtube, so I am impressed. I have been detecting with the Impact on goldfields for 6 weeks and have found it stable in very highly mineralised ground but it overloads in extreme mineralisation as is expected.I have mainly used it in GEN mode with discrimination set to 01 which gives two tones,a low iron tone and a high non ferrous tone..The default setting is 00 and this gives the same tone for everything. Our ground is covered in dense areas of hot rocks with very little junk,so the ability to discriminate hot rocks is a life saver for me.I am assessing the VLX2 mode which on a one gram piece of gold on the ground gave a spiked signal which did not degrade with distance whereas the GEN mode signal became broader with distance and very much less defined.I hope we gold prospectors can share our experiences to become more proficient using the Impact on goldfields.

A member of a UK forum wrote to me that he found a pea sized bit of silver 15 inches deep with the deep mode .He says his ground has high mineralisation.However our goldfields have very high mineralisation and the soil is very hard and compacted and also cemented gravels. I doubt it would reach 15 inches here but at a guess I would say 8 inches.I have persisted trying to use the discrimination modes but the GEN mode is so much simpler and easier.Today I detected in the in the richest nugget producing lead in Australia,Kitty,s Lead, and found only a small bit of rusted tin 3 inches deep.I would really like to fit a larger coil on this detector like the XXL Black Dog but they are only available in Europe.

Hey Gregg, you've hunted with Monte and his Impact quite a few times now and was wonder what you think of it compared to your R2?

I've been checking out your finds with the R2 on all the forums and it looks like you have a pretty good handle on it. You going to try out the Impact?

El, how have you been doing? Good to hear from you. I've missed ya on the last few outings....hope you can make one next year.

Your question "Hey Gregg, you've hunted with Monte and his Impact quite a few times now and was wonder what you think of it compared to your R2?"

Yep I hunted with Monte quite a few times since the Impact has been out. I raise hell sometimes and defend the R2, but the short answer is ....The Impact @14 Khz is the Racer 2 and a Whole lot more.

The long answer is.....Well, it depends.....Do you like simplicity or are you the kind of person that likes many many options to get every advantage that you can out of a machine. The Impact is not a complicated machine and really is straight forward and easy to set up in spite of its many many options. I think the trick or the hard part if you will is actually deciding on the many many options you have, which option is actually the one option that will give me the best advantage in the site that I am currently hunting?

I feel performance is the same, ie: take a Racer 2 and set it up in Di3 (three tone) for example and then take the Impact and set it up in 14Khz the same as the Racer 2, and using same coils I think you will see the same performance. What makes the Impact shine, and Cal Cobra's post a few weeks ago is a great example. He stated that he has a nasty salty/alkaline site that he hunts. The Racer 2 @14Khz was just not performing as well as it should in those conditions. With the Impact, he could tackle that same site with much better performance merely by using the Impact in 20Khz. So if 14Khz wasn't getting the job done, he could easily in a matter of a few seconds switch to 20Khz and problem solved, I don't have that option. In my opinion, I don't think one has a "pure performance" advantage over the other.I think the advantage of the Impact is that it gives you many options in which you can tackle many different environments. A generalized basic example would be if your hunting gold ( low conductors) use 20Khz, if you're in a clean park and silver (high conductor) is deep, try the 5Khz option. The point is the Impact will give you the ability to fine tune for the environment your hunting and/or targets your seeking.

When I met Monte years back, he said something to me that I have pretty much followed to this day "Get a good performing machine and keep it simple" That philosophy has worked pretty well for me. When the Fors CoRe and Racer (Red) first released, it didn't take but a few times using those machines to realize, they did pretty darn good in the iron infested sites I like to hunt. Then they released the Racer 2 and they added one thing ( well maybe two) that I wanted and that was Iron Audio Volume and the tone breaks. I was a happy camper and I have just kinda stuck with the R2....it performs well and it's simple. Today I tackle the nasty iron infested sites with the R2 ( utilizing the Iron Audio) and if I want to hit the cleaner less trashy fringe areas of a site then I use the Fors CoRe with the 5.5 x 10 coil. The Fors CoRe to me has a better balance when using bigger coils.....so they make a great team. And maybe one advantage in my favor is that I am not all invested in one machine. If one machine breaks or fails I can fall back on the other machine. Instead of having all the eggs in one basket, I have a little redundancy............ (but then again who the hell only owns one detector LOL)

Since you asked me specifically my thoughts and opinions, well there ya go and more often than not, there prob wrong :tongue:

By the way if you do get an Impact machine you got a pretty tech savvy guy in your neck of the woods that can prob squeeze every ounce of performance out of that Impact machine.....so if you have a bunch of tech questions send them to Cal Cobra.......but on the other hand if ya want to call so I can brag about a find I made by all means give me a shout :detecting:

But like I said EL, is good hearing from you, hope all is well and really hope to see you again on a future outing.

Most users make the mistake of of increasing sensitivity or gain to over 90 in GEN mode thinking it will give them greater depth when in fact they will miss the smaller and deeper targets. 70 is the optimum setting in GEN mode for nearly all types of mineralisation. I only used the enhanced volume once when I left the headphone cable adapter at home and had to rely on the built in speaker.However it can be used when you get a faint signal.
