Since buying have been glad to have purchased this piece of gear. It is nice to comunicate under water and just write and write if needed to exsplain something rather than hand signals or the old pencil and eraser. Time saving also.

I have used this item at 130' in cold 50 degres watter with no problems. It is quick and easy to write and erase. You can do words or pictures as long as there simple. As long as you have a pocket to put this in its realy nice to have along. Attach a mirror on the back and it doubles as a signaling device.
