This is a pretty sexy sextant. Here is Sven Yrvind the inventor with his sextant or more properly a fixed angle sextant. Instead of shooting the angle, you watch the sun and take the time when you see a reflection cross the horizon. As accurate as a regular sextant and smaller than a thumb.

 

Sven sells them whenever he needs money, but he’s often out sailing, so to get a bris sextant I’ll probably have to make my own.  They are just some glass & epoxy.
