Tired of having to submerge your computer in water so you can see through the gauge protector? Once your screen guard gets scuffed and scratched enough you can hardy read it on the surface between dives, it still protects the computer, but if you can't read the computer between dives it time to replace it. The adhesive plastic screen guard is designed to protect the Suunto D-Series Dive Computers.
These are a MUST! The computer is way too nice to not keep protected!
