I notice there is three different frequency's which pretty much cover what most of the market offers. I would like to know a little about the higher frequency's. Im not ready to turn loose of my proven F75 or AT Pro. But these two detectors dont have the higher frequency one would use say for nugget hunting. I see the Impact is sensitive enough to find small items. Have you had a chance to test small gold with the Impact? Any machine that can find small items like that is worth looking into. I am confused as to what kind of detector the Impact is? What would you call it TNSharpshooter? Relic, coin, nugget?
Well I'm not versed in nugget hunting,,,but Impact is I think worthy detector for relics and coins and jewelry.
Highest frequency is where Impact has the highest degree of separation in iron and nails,,,but remember high conductors using this could be depth limited moreso,,Uaing 14khz does provide some very good separation,,less so depth minted overall on higher conductors,,,5khz,,is more crippled with separation and unmasking,,but on higher conductors can be deeper.
Notice the Hoover boys video??
I'll bet I could take Impact back into that site and make some finds using. 20khz and stock coil.
No cut and dried answers really,,Impact with it 3 frequencies is nice.
Your F75 no match for Impact when nails and iron enter into the equation.
Notice what the gent said in video,,about F75 in that site.
Also remember,,,hunting in the wild,,,one must locate target,,very possible to sweep F75 over some of these Impact detector located targets and give tone or some thing telling user coin,etc is down there.
I have already said on this forum,,,gotta watch head to heads done with you tubes for this very reason.
Impact,,closet thing to a Deus I have ever ran in and around nails and iron.
Impact IDs deeper than Deus.
