I watched a video where a guy with a waterproof metal detector takes a trip to the Bahamas or big beach resorts where wealthy folks play...he goes out in the water and finds most items in chest deep water, claims he finds enough watches, rings and jewelry to pay for his trip, but admits he spends a minimum of 8 hrs per day using his metal detector. Does not sound like a super relaxing vacation.
I think I could be that guy in a few years, probably relaxing to him. 😄
