I recently bought a uwatec Galileo Luna. It tells you pertinent information pretty clearly such as depth, psi, max depth, dive time, etc. Some of the main screen information is a little tricky, such as how the rbt correlates with the no stop time. Also, how to operate the plan mode and dive log functions. The manual is really complex and doesn't help a whole lot. If you own one and could give me some tips on it id really appreciate it.
