Hand signals only get you so far. A wrist slate straps to your forearm and gives you a writing surface you can actually use mid-dive - buddy notes, depths, gas pressures, compass headings, the name of that fish you'll never remember topside. Because it's on your wrist, both hands stay free and you're not unclipping anything to read it. The built-in eraser means you wipe and reuse it dive after dive instead of running out of room.
