Unbelievable how a little bit of water can
hinder experienced treasure-hunters for ages
to check out if there is something down a hole or not...
There exists gold-mines in Africa which go down 1000s of feet!
If those would work the same way they wouldn't come just 50meters below the surface.
Who cares about the water anyway, they have to dig away the gravel, dirt, mud and
whatever first with some remote by steel-wires operatable open-close bagger-shovel.
This can be done within a few days or weeks if they remove each hour 1 cubicmeter
of material. Sink the open shovel down, close it, drag it out, remove the stuff and do
this again until the hole will be empty enough for a little diving-trip.
Another "cool" idea would be: Freeze the whole da**ed thing by streaming
liquid freezing gas down and then use dynamite so you can remove the
ice-blocks and no more water can come in, because its all frozen 5meters thick.
Even blowing down icy air in winter-time already could work if its cold enough.
Or most easy: Please just dig a flat tunnel from the outside and don't make me crazy !!!
The main problem will start if they should find nothing inside the hole
or better - at that under-water-cave:
Then they will think it was the wrong place and they can start to dig
100s of holes all over that island - this is when the real "fun" starts ....
