Review on 🤿 Promate Scuba Dive Waterproof Writing Slate 6" x 5", In Stock, with Compass, and Glow-in-the-Dark by Vivek Allen

I'm a scuba diver but I'm also returning to swimming for fitness and triathlon. I use it for swimming training. As part of my swim training, I do sprints and try to keep track of my time. This tablet is great for this type of use. I put it on the deck at the end of the pool and then start sprinting against the clock. When I finish a sprint, I write the date, distance, and time of the sprint on the whiteboard. Then I do another, and another, and another. At the end of a workout, I transfer my time to my worksheet/software to track my progress. The board appears to use a regular wood graphite pencil (included). It simply writes on a slate. It could be read poolside without much effort, but I imagine it would be difficult to read during the dive at any depth. For diving I would prefer a black, bold pen that makes very clear and legible markings on the board. . There is NO grease pen for this tablet (although they are sold separately and easily attach to this tablet).
