Here are my Experiences on Gold and Freq.
I started with a BFO Crusader Off the Wall detector.
It was running at 360KHz.
It could find a Penny at a honest 5".
Being of the All metal sorta machine they Show Gold on the None Ferrous side of the scale but you would not find a 1 gram nugget with it.
(It did find me Good Gold by using it to find Black Sands Deposits to Sample)
My NEXT machine was a Garrett ADS running at 15KHz.
Now that machine could and did find gold Nuggets down to 1/4 Gram down to 6-8 inches at times.
Things had to be going just so to hit the 8" mark.
Most of my hunting at this time was along Open Bed Rock so it worked to the most parts in the Crevices and Cracks if not so deep. This was with the Stock 7 or 8 inch coil. Concentric type.
While I was away from Camp doing some Crevising That machine got Robbed out of my Truck one day. That Sucked
NEXT I purchased a newer Garrett Deep Seeker runing in the 5.5KHz range.
This beast was HOT as HELL on Silver coins and Copper but just didn't do the Gold so well.
It would not see a 1/4 gram Nugget two inches from the coil being waved like a Raped Ape or Standing still.
Through the BONE YARD on another Forum someone sent me a Garrett S3. The thing was all messed up but I got it working replacing the Speaker and a switch.
It was running at 15KHz.
Again it could and did sing on the 1/4 gram stuff most well down to about 4-6". Mind you this was a Cheapo Introduction type detector made for Coin Hunting.
I think they cost like $130.00 or so New.
I still have this machine and Never plan on Selling or Giving it up.
The Little Bounty Hunter Camo LS BitBurg gave me can find a Backing for a 14K Ear Ring in Dry sand at the Kiddie Park down below 8-9 inches of sand.
Mind you that's not the stuff you work out in the Desert.
It runs at 6.5KHz.
The 14K Gold has Silver or Copper as a Doping in the Alloy.
It will not see the 1/4 gram nugget at 4" no matter what setting I have it on.
Gold Hunting is All Metal, Sense as high As it will do and Hum Away.
I have used the Fisher Gold Bug runing at 70KHz.
Now those beast will find Coacroach shit size gold that will drive you crazy tring to Isolate from the Sands.
There also hot on Un Wanted Goodies.
The little Falcon runing at like 300KHz finds the Spects of Spects. Them there will drive you Nutts if you don't know what your seeing!
So Yes, I Have the Mind Set that Freq does have a Bearing on what the Detector will or will Not See.
Did you Know that the Little Compass Pease Of Junk 94B that every one chucked out running at 100KHz Blasting through Iron Junk was a Killer on Gold?
Ok it was as TR but it Talked!
TR Sucks because you have to hold it at a level sweep and hear the toons.
People now days want Instant Gratitude and Have little intrest what there Brain can do.
They just want the Dig or No Dig . LOL
I love them guys! They walk over all the Good Stuf.
