Superb Dive Computer Storage

By Brian Holf on 12 Jul. 2011

Thanks Northern Diver, this is perfect size and fits my Suunto HelO2 dive computer (some other cases don’t).

Great piece of mind, if your dive computer cost a few quid and you don’t want to just chuck it in your dive kit bag and of course, in ever fashionable black.. Top job.

Brilliant little case

By Neil Bailey on 21 May. 2020

I was looking for a protective case to put my two dive computers in, rather than in a ziplock bag thrown in "my diving box". The cases arrived today, in sturdy packaging, and they are brilliant. I put my Mares Puck (with watch strap) in the first one and zipped it up, and I put my Suunto Vyper with bungee attachment (rather than strap) in the other. Both fit perfectly and are held snug with the foam insert. Great product, ample protection and it hold them in snugly. Glad I bought two on first order. Now to find a matching mask case...
