Probably say too much as usual, but I'm not giving out coords.
I hunt the beach often, mostly just to relax and get out doing something.
If you divide the beach into 5 sections:
1. Back of the beach by the dunes, or where folks park if it is a drive on beach
2. Towel line, area between the back and where the sand starts to slope
3. Slope
4. Beach Break
5. Knee to shoulder deep
1. Back, I have found mostly change and beer bottle caps in this area. Have found some interesting finds in the hard packed sand where people drive, but you need to hunt that very late in the day when cars are gone.
2. Towel line, the favorite of the dry hunters, I have only found one ring in two years of hunting. Mostly clad, tools and pop tops.
3. Slope, this includes the area of sharp drop after some nasty whether. It gives you a natural extra foot or so of depth and have found a couple of wedding bands in this 3 foot section. If it is just a normal slope, I usually only find change and beer bottle caps.
4. Beach Break, I have found many rings, toe rings, nipple rings, lots of big loop earrings (deep), watch (which I still wear) etc. I also find lots and lots of rusty nails and bobby pins.
5. On a calm day, this is the most fun, many less targets, but usually more interesting. While you can find some pop tops, I would say that 2 out of 3 targets is something of interest, whether change, a piece of something, or jewelry. In this area, I have found many many earrings, rings and large change, quarters etc. I have also found a few pairs of glasses, which don't fare well in the scoop.
Another advantage to hunting the water is that you stay cool. Invest in a pair of dive booties and a dive belt to hold your stuff. Make sure your MD has a detachable unit that you can belt mount. If the water is moving (like the beach), then use a stainless scoop with some weight to it.
When you first get in the water, it is VERY VERY HARD to dig targets. After my third trip to water hunt, I was ready to give up. I got out with three finds and was so tired that I could barely walk back to the car. I tried it again a week later, and it was suddenly easy! You have to learn how to hunt all over again, with a distraction of a wave hitting you every 5 seconds. If you hunt on the Gulf coast of fresh water sites, the "break in" period would likely be shorter.
My personal feeling is that hunting dry sand is mainly good for exercise.
