Hey, just looking for some solid advice on what can be accomplished. I had a boating accident last week and dropped my Glock 21 (.45 cal) still in its holster. The water is about 5 foot deep and the silt under it is about 12-15" deep. The water has 0" of clarity. I know within a 30' radius of where I went down, but have yet to find anything that I can use from a boat to find the location. I don't have dive gear so I cant stay under for long periods sifting through silt. Any advice?????
