Dixie,
It could easily be that the targets have sand covering them deeper then you can see them till a storm removes some of the sand.
I was hunting Daytona last weekend, it was the worst hunt ever. I found a total of 2 quarters, 2 dimes, and 2 pull tabs. I had no other targets at all.
I was using my waterproof sovereign gt, I know from past experience it works great, both in the water and on wet sand and it goes deep. I have the WOT on it and it is a HOT coil, I have pulled good targets up with it that were over 3 full scoops deep with my Beach Brute II scoop, and that was with me standing on it like a shovel and working into the beach till it was buried to the bottom, easily 12" inches. The quarters and dimes I found were deep and signal was not that loud, but that was it.................To make it even more dismal, the eye candy wasn't there like normal either.
There is no way other hunters have cleaned the beach out, I don't believe you can clean Daytona out of good targets, it is too wide and long. I firmly believe it was sanded in so bad that the goodies were too deep for me to see with my detectors. Hoping for a good Northeastern this winter. I don't pray for hurricanes any longer, after 2004 you can keep them, when you get hit 3 times in the same season it is way too much, a good tropical storm is another story and is welcome, but the huricanes can go somewhere else.
I was in North West Arizona on vacation and I want to move there bad. No salt water beaches, but you have several shallow rivers that are used hard and have beaches, plus there are the mountains that have abandon gold and silver mines, as well as old buildings that are 100 years old and older. You also have metorites...........
Maybe one day.........................
