currently working on a "tac-board" or "nav board" for precise underwater navigation.
View attachment 7457592 it essentially a fancy way to say "ship compass with a watch mounted to it".....
the ships compass is more precise than wrist mounted compasses that we usually use, and it gives us the ability to mount depth and bottom timers to it at well.
its usually held in front of the diver as they swim along.
View attachment 7457589 now for some reason a lot of places seem to restrict sales of these to police/ military.....for.....reasons.
and when they do pop up on Ebay, they are ungodly expensive.....
so most people just make their own out of an old cutting board
View attachment 7457594 well i found a design that actually looked pretty easy to fab up
View attachment 7457595 so i channeled my inner Chinese and reverse engineered it
View attachment 7457588 had the chassis water cut from 3/8" 6061, now to do all the final finishing and then likely have it sent out for Type 3 hardcoat.
View attachment 7457596 should have some updates in a week or so.
