Mares Magnetic Scuba Shaker
I have purchased a Magnetic Scuba Shaker for one reason and that is not to make any sound when walking around with your scuba equipment. I was dissapointed to realize that this magnetic shaker does not really work as I thought and I still make noice when walking around with my gear, even it does unintentional sound under the water.

Der Shaker ist sehr leicht und sehr gut verarbeitet. Er hat die ideale Größe und ist nicht zu klein. Durch das besondere Magnetsystem klappert es nur mit einer Abwärtsbewegung. Unter Wasser ist man damit sehr gut zu hören, was wiederum für mich sehr entscheidend war.

I have seen a bunch of variations of the noise makers, but I was drawn to this one the most. My only concern was if it would rattle too much unintentionally. When on land, it does rattle quite often so this made me worry. But rest assured, underwater it works perfectly. It is very loud and easy to use. The one thing that might not be obvious is that you have to "reset" the shaker after use. After using it, the ball bearings are still loose, so you have to invert the shaker so that it reengages the magnets and locks in place (you will hear a snap). Some might ask why you need something like this for diving. While I think it is obvious, let me share a story with you. In my first dive trip ever I went to the Galapagos. On my final dive, our dive master took us deeper than we were supposed to at 30 meters (I was only an open water diver certified for 30 feet). I wasn't aware, because I was using rental equipment that was not working (another big mistake). I was with a group of 6, just a few feet away from my buddy when suddenly lost vision. Everything went black, but I was still conscious. I tried to grab my buddy and signal for help, but I was in the back and even though I was just a few feet away, no one realized something was wrong. My dive buddy was following someone else (who she thought was me), and the dive master must have not been keeping tabs on me. I ended up being left alone for 3 minutes under water completely blind. Fortunately, I figured out that I had a mask squeeze, cleared my mask, and restored my vision (albeit very blurry and seeing double). I couldn't find my group and had to surface. The boat directed me towards my group, and I rejoined them later on. To my surprise, no one even realized I was gone and only realized when I appeared. While a lot of things went wrong here, having a noisemaker would have quickly brought attention to me and prevented the situation from escalating. That is just one example, and I am sure there are many more. That is why I have a noisemaker for me and for my buddy, and would dive without it now.
