HOG brand compass with bungee mount and bungee. A must for advanced divers and required equipment for advanced training. 

This compass set is a lot cheaper to the Suunto set. The Suunto set is about JPY 10,000 for the compass alone, then another JPY 2,000 for the bungee housing. So, this unit will cost about half as much as the Suunto.
