bugger.
As usual left it to last min to begin getting gear together for trip (next week to Philipines).
Boris is not smelling too fresh - must have put it away damp

batteries totally flat so pop new set in.
anypoo...
as im changing batteries I notice the rear display (electronic cap) is cracked!
Bugger bugger bugger.
bugger.
Its a good crack. It looks like the crack initiated from the area around the lower wetswitch bolt head
i did note the batteries had leaked and were flat - can a faulty leaky battery generate enough pressure to crack the cap from the inside??? or maybe i damaged the cap while moving my unit around....bugger
its strange - but i am 100% sure there was no crack when i put the unit away last time (its a big crack and hard to miss)
sooooo lesson to learn - if your using the old style rear display* (one with wetswitches) have a reg check for cracks
*pressume new model with auto breathe start up doesnt have the wetswitch bolt.
electronics still work (and the rear display has also come back to life) - but the crack clearly will cause a flood if i dive it
