The Shearwater Peregrine Silicone Case is a fitted silicone cover designed for the Peregrine and Peregrine TX dive computers, matching each model's exact housing shape rather than a generic sizing. It covers all sides of the computer, guarding against scratches, bumps, and everyday wear that build up over regular boat and shore diving. The material is lightweight and flexible, stretching into place without tools and holding a secure fit once installed.

Cut-outs align with the display and both buttons, so screen visibility and button access remain unaffected once the case is on. It's water- and salt-resistant, suited to routine underwater use rather than treated as a substitute for careful handling of the computer itself. The case is available in black, grey, and white. It fits both the standard Peregrine and the air-integrated Peregrine TX, but is not compatible with other Shearwater models such as the Perdix, Petrel, Teric, or NERD, which use differently shaped housings. This is a fit accessory only and does not include a screen protector for the display lens.
