Well i don't dive but i was hoping to take a ROV into "rip tides"? to discover treasure.? What do you think? would my ROV get ruined.? Also how would i find one of these?
NOTE: This is my own personal opinion.
You shouldn't have to dive to take advantage of Great Lakes rip tides.
Go to most any heavily used beach anywhere on the Great Lakes and look for the warning flag. If there are waves of 3 foot or more there's most likely a rip tide. In layman's terms a rip tide is water built up on shore that suddenly rushes to the deep.
People drown in these because they are pulled out into deeper water and they can't swim against the returning current. If you tried to water hunt while a rip tide was active you could end up losing gear and maybe your life.
You would want to hunt the shallows right after the rip tide subsides and before everything exposed is recovered again. So, one would almost have to live close by an area to take full advantage of the situation.
If caught in a rip tide don't try to swim directly toward shore. Swim at an angle back to land.
In the Great Lakes you're looking at a situation in miniature of that which exists on the ocean coasts. There goodies come in with the tides or hurricanes, etc., and are sometimes deposited many feet up shore. With Great Lakes currents and winds the goodies are dragged from shore toward the deep water and then gradually returned. The sand is constantly moving. In fact, even the dunes are moving.
This is why very old coins found in the Great Lakes are usually badly worn.
I'm very sorry to say that much of our lost treasure on Great Lakes beaches is probably being swept up by beach cleaner machines.
What people don't know is most likely some 2 to 6 feet deep are goodies they'd never believe. They're down there in nature's slow but sure sand blaster. Some of these things may be exposed for a short time due to the workings of the wind and waves.
