This clear cover has a sticky side that gets put on the face of really, any dive computer but these were made with the Epic or manta in mind. 

These are the exact same cover as the Oceanic Geo Series and would work perfectly on them as well.

Note for the end user. This is a clear circle that you peel a back off to stick onto your computer. This back is very invisible so it takes a moment of patience to get the backing off or even to find which side it is on. Easy to do if you know that this is what needs to be done.
