TridentScuba Tank Banger Underwater Signal Device

My wife wanted one of these. We are SCUBA divers and she wanted it to signal me. It does what it is supposed to do and is made as expected. I have a hearing loss from my years in the Army so I don't hear it most of the time so it does not get the job done. The product is OK but they are not a good solution in my case.

Ever dive with the human version of Dory who swims off all the time, right at the time you find something really cool that you want to show them, but you can't get their attention unless you swim after them, then you lose what you were looking at? Well, you don't have to do that anymore with the tank banger. Just grab the hard plastic sphere, give it a yank, and you'll get everyone's attention, whether you want it or not...... but at least you will get the attention of your dive buddy, then y'all can just keep swimming!

It works. The rubber does decay after a couple of seasons. For dive groups, I recommend the Lead have a shaker alert, which carries much further, and give each diver one of these so they can attract notice as needed, for critters or problems.

Great product! - effective for getting others attention up to 30 feet underwater. Simply to use / easy to stow away.

We got this in blue and pink, one for me and one for my husband. They work great and not sure how you can give this product anything but 5 stars. It gets the job done!
