<td valign="top"><p dir="ltr">Hi Jim, when we were at the convention, I had downloaded Nav charts and installed them onto a program I have on my nexus tablet which has a GPS system. I was able to not only able to navigate around the shallow coral heads on our way to conch reef, I was able to set way points and see lat long positions and speed. The other software provides compass headings. Not sure if that program is using GPS and inertial sensors. Most likely though. </p>

<div>Hi guys, I've been searching the database looking for a discussion on the best choice of a compass for use in my submersible. I looking for dash mount, limited to 3" dia. My tablet will provide headings while on the surface, but not so much under water. Any thoughts would be appreciated.</div>
