I like to hunt the lakes on calm days on monday or tuesday mornings, I work 7 pm to 7am so by the time i get off work and to the lake its about 730 am and I usually have the lake to my self, I walk the bank with my detector in hand but not actually in use, at first, I eyeball the shallow water near the bank when the lake is calm and the sun is just comming up the gold will reflect the light, I wear polerized sunglasses and it allows me to see through the water with ease, as for the silver I look for a silouet of somthing uniform such as a circle or a circle with a hump as most rings are, and here in dallas the silver is almost always jet balck when it comes out of the water, and the gold is orange on the side that was in the mud, after this I go back over the same spots with my detector to get the stuff out of sight and just under the silt, when I get a good signal I fan the silt away to keep from bending over for the hundreds of pull tabs that are mixed in with the good stuff. as far as how deep to hunt , the best results I have are when the water level is normal in the summer and people are swimming, the level where their hands begin to touch the water is where I find the most, I think suimmers in lakes usually stand in water just at their waist with their hands in and out of the water, that makes their fingers shrink just enough for their jewlery to slip off, and usually when they are swimming the water is stired up enough so they cant see the bottom, then the stuff is lost, in wait of a couple of guys like us,,, I found a small gold ear ring this morning it weighed one gram,, not much but better than the avon toe ring I found with it ,
Great hunting,, and good luck
