Yeah! Me too! I cringed every time you thrust your hand into that sand. I have found too many bottlecaps still connected to broken bottle tops. Nasty weapon and will cut the dickens out of you. Two suggestions. 1...After you pinpoint by the sound, fan that spot really hard with your hand. Make it work like a water jet. It seems to settle down really fast and you can move lots of material that way. 2. Know those 3 pronged garden hand trowels?? I have one looped around my wrist and when something is down in the muck like that, I scrape down deep and then pull towards me. If you don't even hit the target, you'll move a lot of the bigger stuff out of the way. Rocks and cans etc., come out of your 'target' area when you scrape like that.
I have never counted on my gloves to protect my hand. A 1/4" of wet suit material, usually much less on gloves, doesn't afford much protection. I have found at the end of a day my wrist is fatigued from fanning so hard and so long. Try it a time or two and you'll be surprised how deep you can get. The nice thing about it is the lighter materials, sand mud, bottle caps, etc., get jetted away, but the heavier things tend to stay in the hole you are digging. Yeah! You can jet the coins out of there too but it's much harder as they are heavier. The gold usually stays put. And it's massive fun to watch it gradually being uncovered.
Nice video. Glad to see some other folks are doing the Hookah. I have a Hookamax 12 volt DC unit. Needed quiet where I dive. Take care...jim
