Scuba Choice Duiken Veiligheid Tank Rammelaar Stick Signaal Bell met Clip

The plastic cap with the magnet fits so tightly that it is very difficult to remove. This makes it practically unusable under water. Waste of money.

My buddy and I lost our group last time we dove (water wasn't very clear) and used my camera's handle to hit the tank and make noise so we can be found. It worked but after that experience I decided to buy the real thing.This noise maker is very noisy outside the water. It produces a vibrating sound that should go far under water. I can't wait to try it in my next dive.It is bigger than it looks in the pics. The cap is really tight, so it shouldn't fall, but maybe hard to remove with gloves.I recommend it for the price.

Work perfectly, it perfectly loud enough. I know some folks have criticized it for not being loud enough, but those are likely also the same folk that you dive with that are always making noise under water that scare everything into hiding, ya you know who I'm talking about. I retied the cap on mine, and haven't had a single issue with it. Have used it on over 20 dives thus far and its great.

Perfect and a good price

Not very loud under water never got anyone’s attention had to shake so hard and cover fell off while diving so now annoying rings whenever moved on land
