A good beach detector is going to be expensive. The salt water environment is one of the worst to work in.
So you are going to start by needing a waterproof machine. Some non-waterproof machines work in the wet stuff, but one splash of sea water and your non-waterproof detector is finished.
So now you need to think about pulse induction vs. discrimination.
A PI detector gives great depth, but no discrimination at all, which can be really tough in trashy areas on the beach. The cheapest waterproof pi detector worth owning will run you around $600 new.
A discrimination detector is VLF running at two or more frequencies. They usually do not go a s deep as a PI detector, but you can discriminate out iron trash without ruining your depth which a lot of people see as a real plus. The cheapest waterproof VLF detector of this kind that I've seen is made by White's and runs around $800. A favorite is made by Minelab called the Excalibur II and runs in excess of $1400 new.
Expensive? Yes. But many find not digging deep holes for iron flakes makes the cost worth it.
If you go cheap on a beach detector, you will regret it. If you have to go cheap, get yourself a land detector and stick to the dry sand. Forget the wet sand. It will not work well there.
There is one PI machine that I know of that does have discrimination and that's the Garrett Infinium LS. It is a true water machine that is waterproof up to 200 ft. It costs a little over $1,000.00. I've never had one or used one, so I'm not sure if it looses depth as you increase the discrimination or how well the disc works on the machine. I've read good things about it and it's supposed to work extremely well in mineralized soil. A lot of people use it on land for relic hunting. As as matter of fact, it is one of the machines that is a favorite of the folks who go to the DIV hunts in Culpepper Virgina, because of the hot rock and red clay in that area. The LS is the next machine that I am going to purchase.
E-Trec, I have to disagree with you a bit on that mark. While both the Infinium and the Sea Hunter have knobs marked "discrimination" I have found they just flat out do not work. I have also found that when they are used, the depth of the machine drops off significantly. Perhaps you have had a different experience. I know lots of folks like the Infinium for land use.
The other problem I have with the Infinium is that when purchased, it is not not set up for salt water hunting. You have to purchase both the waterproof headphones and a mono coil that will run stable in the wet salt sand separately. Garrett will happily sell to you for a hefty price. So hefty, in fact, that it probably makes more sense to purchase an Excalibur II from Minelab which gives you real discrimination and excellent depth, and is just as heavy.
I wish Garrett would offer the Infinium as a salt water package, but they only offer it as land package. If they offered the salt water package, they might sell more units.
