The underwater slates and notebooks shown here are a must have item for all scuba divers, allowing you communicate quickly and accurately or just make notes or maps. Easily cleaned off after the dive, a diver slate or note book should be with you on every dive.
Divers have tried a lot of ways to clean their slate and/or wetnotes: kitchen cleansers like Ajax and Jif, as well as toothpaste and sandpaper. But they all pretty much make a mess and are not very handy either. The solution is Trident Erase-A-Slate. It looks like a small sponge, but it's not abrasive and it's not soapy. To remove your carbon/graphite pencil notes in a moment just wet it and wipe. We aren't talking elbow grease... just wipe. We don't know how it works, but it works great and there is no soapy residue so you can just throw them in your dive bag or dry box.
