It goes in The Water
It goes without saying, or maybe it should be said that when purchasing a metal detector, make sure that the coil is waterproof if you plan on doing any searching in the water like I was doing while searching the remains of an old fish hatchery from the 1950's in this photo.
Although the control box of my metal detector is not waterproof, there are metal detectors available that are totally waterproof, allowing them to be completely submerged while prospecting for gold on deeper gold bearing creeks where gold nuggets can be washed in to deep pools by the rushing water.
This is where you could possibly do some prospecting with a waterproof metal detector, and if it looked promising, you could then work the creek bottom with a small floating gas-powered suction dredge.
Years ago my dad and I had a small floating gas powered suction dredge with a combined sluice that we took to the Yukon, and had the opportunity through a friend to work a gold claim belonging to his friend.
We didn't strike it rich, however it was a lot of fun looking for gold and we did get some color that we washed out of the sluice traps with a gold pan.
The orange Garret pro-pointer that I am carrying is also waterproof making it submergible.
