I am looking to give the students two slate material packets for an Advanced course.
The packet will contain two small slates, a pencil, surgical tubing and a clip.
For the first one, they will draw the coordinates for a navigation exercise on the top of it in waterproof marker and they will glue a compass, similar to this one:

on the slate itself to create sort of a DIY TAC board:
RJE International - DIVER NAVIGATION BOARD
They will use this for the navigation part of the course. They have the entire course mapped out ahead of time, can practice and visualize it, then execute it underwater using lines for kick cycles, floats, etc...
The second slate will be used to map out a shipwreck. They draw the basic shape of the wreck based on known data and use the preexisting drawing to map out the wreck, take measurements, depth soundings, etc.. while exploring the wreckage.
On the back of that slate is a grid where they can keep track of marine life for marine life ID dives.
I am going to bind them together with some surgical tubing and give them a clip to attach it to their BC.
I think it will work better than a store bought slate and create some flexibility.
I will post some photos when complete.
