Hi,

Dont' buy the protective cover at
http://www.lumb-bros-das.co.uk/acatalog/Dive_Computer_Protective_Covers.html

It is absolutely crap, mine broke at the first dive, the plastic is as thin
as an egg shell, it will break unless you do not use it in the first place.

I have instead found a better solution to the problem. I have found an old
suunto solution boot and a protective cover for it and it fits the apeks
nicely, you can see the result on
http://www.project-safe-diving.be/cover.jpg

The suunto's protective cover is really thick and won't break like the
eggshell type mentioned before.

Some pointers:

SUUNTO solution boot  example: http://www.danshop.com/suu5766.html
(for mounting on hose)

I'll bet you find others ....
