I just received a BHID 300 yesterday, the first water detector I have ever owned. This Monday I negotiated with my wife and am calling it my "ring challenge" day of hunting. I am going to head to the beach Sun night, hunt all day off and on, hit the low tides and see if I can come up with a ring or two. This would really impress my wife and help pay down the $915 I paid for it. Anyway, my question deals with the noise level. I tried putting several different things in the headphones to cut out on the volume level, but none seemed to muffle it down to a comfortable level. I have finally decided that earplugs are the best solution. I was just wondering if anyone else has a method that has helped them. Not sure why there is not a volume control on this detector. Thanks, Bryan
