nails in beach scenario

I detect an old fresh water beach , that at one time had a long wooden pier . That pier bunt in the 1960,s leaving thousands of nails . There is also lots of gold jewelry amoung these nails . What settings would you guys use on your excallibur , if you hunted that beach , from shore to the 6 ft . depth ? - mike
 
I use Excals on Florida salt water beaches and I don't normally hunt fresh water. Fresh water in Florida has alligators and water moccasins.

I don't think the Excal is the right machine in that application. The excal nulling on iron has a time lag and it would drive you crazy waiting for it to come out of null.

An excal with a small coil (8 inch), hunting in pin point than switching to discriminate to check a target may speed up the hunt.

I don't own one but maybe an AT Pro is what you need?
 
I luv my Sovereign GT. But heavy nails,ain't happining! I how found the Tesoro Mojave to work beautifully in nails. My AT Pro and MXT can't touch it. Very impressed with that lil $250 machine. I've even worked it just outside of a 33KV substation without any interference,where none of my other machines will run. Just wish it could go as deep as my GT.

Assuming that the Excal is the only option for the detector, I would use all metal with careful target examination, ignoring elongated responses and one way double taps. When a round solid target hits, then go to discriminate to see if it is non-ferrous.

This should avoid a lot of the nails, but bottle caps would be problematic.

Good luck!

You may want to try sensetivity set in auto while in disc mode,disc set to 1.. you will still get spits and sputters on some iron but assuming most of these nails were simular in size and composition it shouldnt take long till you recognize iron vs non ferrous targets... masking is obviously gonna be an issue unless you hunt in all metal but one has to ponder what the ratio of iron to non ferrous targets is,,,100 to 1, 1000 to 1??? swing as slow as you can that will still give a signal...
 
Ya its going to be a slow process if working with a standard coil. Id start off by reducing the sensitivity a good bit...... more sensitivity the more coil HALO and near targets to null on. Reverse disc can speed up recovery and you will get some near targets........ masking is the issue. You just need a faster recovery machine or you will have to wiggle your way thru the trash/iron. Thats the problem with hunting fresh water....... it just takes forever for targets to disintegrate.
