Review on 📋 OptimizedScuba Choice 6 x 4 Diving Slate with Graphite Pencil by Samik Drusky

I really like the quality of this slate tray but after using it I had a small problem. The supplied pencil cannot be erased under water (or during service). After writing a note on a board about 25 meters below, I found that if I wanted to continue communicating with her, I had to write in small letters or use the other side. Pencil marks are not erased. Have tried wiping them off the surface and even tried toothpaste to no avail. I need to find a softer graphite pencil or something similar to use this in the future. A slate, clip and plastic string are all fine, a pencil is essentially a golf course music pen.
