    I have had my mobile phone inside my drysuit for the last hundred or so dives, doesn't seem to effect it, so safe to assume that a camera would be the same. Unfortunately, they are not too fond of getting wet. If someone was to make a camera housing with an ambient pressure regulator, or even an ambient +0.1bar regulator, it would work without risk of flooding.

    Pressure

    I thought a number of people have killed phones (especially "glass" fronted smart phones) by leaving them in under suit pockets, etc.?

    Might just be hogwash then.

    The only one that I killed was when I accidentally left it in my thigh pocket.

    I had to think a bit about 3) Cos I wear "normal" undergloves in my dry gloves not neoprene. They dont compress because the air from the suit freely percolates through the material maintaining the loft. Of course the bubbles in neoprene undergloves do not communicate with the air under the outer dry glove and so are compressed. So while these fancy neoprene under gloves may be good for insurance in case of glove holes they will be less good as insulators at depth? Anyone disagree? Have I got it wrong.

    If one enters a cave system at say 40m and the cave has an incline of say 10m what depth will your gauge read?

    Not strictly true for 1). You would expect a small rise in pressure as the housing reduces slightly in volume (Hooke's Law) due to external pressure. It all depends on the flexibility of the housing material and the rigidity of it's design.
    I'll think of something witty some time soon.
