Shearwater Perdix/Perdix AI White Silicone Protective Dive Computer Sleeve Cover

The Shearwater Perdix was the best thing I ever bought for diving. A protector was the second best. I've got one of them here in a Chicago suburb, not in China, awaiting your purchase to rush to your mailbox so that it will be in your hands very soon. This one is white and I have another in black. Both sealed (the black is hermetically sealed, and the white is sealed in zip-lock-style plastic), never touched by greasy, filthy hands, and are unused.

Helpful notes when making your decision:
Shearwater does not make an OEM protector. This is from a third party. Also note that I have personally tried the aluminum covers from the France manufacturer. They're awful, only because they have to use a bungee to keep the aluminum protector affixed to the Perdix. Try to keep that bungee tight and constantly in perfect place during a dive. Yeah. You understand now why I lost one during a dive. Not these silicone protectors.

In sum, they're great. I have only two left. I sold all of the others.
