I managed to find one true glory hole last summer.
From the beach carpark, I could see a darker blue spot in the water. It was oval shaped and I figure about 5metres by 5 metres, and about 10 metres from the edge of the sand. Sure enough, it was loaded with many coins, some gold rings and similarly weighted items. There was no pulltabs, bottlecaps, foil or any other typical rubbish as these had been swept away <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt="

"> The dropoff into the hole was about 1 metre, so this then put me in about 5 feet of water. It took me almost 3 hours to clean it out as many targets were all bunched together. In fact, I got most targets out by just blind digging in order to thin all the signals out a bit and then I could manage to isolate separate targets.....I came out bloody exhausted and my pockets were full !
It was an adrenaline rush when all the signals starting ringing out.....now if only I could determine what conditions produced this hole as it has never appeared again <img src="/metal/html/cry.gif" border=0 width=40 height=15 alt=":cry"> <img src="/metal/html/cry.gif" border=0 width=40 height=15 alt=":cry"> <img src="/metal/html/cry.gif" border=0 width=40 height=15 alt=":cry">
The key to water hunting (for me anyway) is to feel the sand beneath your feet...if you wiggle your feet around and start sinking easily, then move on as it's only good for drops within the last 12 hours or so. I've done tests in loose sand with small lead sinkers and they are undetectable within a very short space of time. If digging into the sand is hard work then you are in the right spot, especially if older coins, etc are coming up....
.....I've sidetracked a bit as usual, I'm sure you're up to speed on the basics !
