Zack W In the owners manual of this item it says: Your compass is weather resistant, and can withstand exposure to limited moisture. However, like all electrical items, water can permanently damage the compass. Keep your compass dry and do not submerge. Enjoy it! Zack.

SunnySports S Actually I would advise against it. The magnetic pull can be affected by large metal objects (cars) and electronic devices. Stay safe and have fun out there! Neal

SunnySports S Extremely accurate with fresh batteries.
