Robin,
The Ikelite housing is transparent, so I think you'll notice. I thought about a moisture detector, but decided it wasn't worth it. As Heather Hammond said to me "just make sure you don't flood it, buying a moisture detector may make you complacent"

Insurance is tricky. Most companies want a premium based on total value of kit, usually 8-10% a year and some insist on insurance for dive kit with it. When I totted up the total value of my kit it worked out to be about £350 a year. Now in most cases I can see failure will occur to only one part. So if it's one of my strobes and it dies I can pick another one up for £400. If the housing floods I may just kill a camera, again I can pick up another for £400. The only time I kill the whole lot is if I have to let go of it for any reason; this still wont be the whole set-up as I can't have macro and wide-angle on at the same time. My feeling is it isn't likely to make a claim that often. So I don't insure. That's a big risk I know, but I simply can't afford the insurance year on year. My plan is to get the housing serviced every other year and replace o-rings annually, that's my insurance.

Just my opinion,
Rob
