A reference book of compilations authored and edited by Jacques Cousteau along with the Cousteau Society is "The Cousteau Almanac - An Inventory of Life on our Water Planet" Great reading for any diver or human being. It covers environmental issues from abalone to zooxanthellae.
Don't know much about the second stage but I am familiar with the bottom timer. I have a couple of them and I still use them as a backup instrument. If you pressed on the diaphragm on the back the second hand moved it probably works. Keep holding it down and see if the minute hand moves. If...
@aquaregia. You are right...it actually works. Suck the water into your mouth using your cheeks, air will flow into the reg. Then forcefully spit the water back into the reg, the air will stay in and some of the water will flow out the exhaust valve. The reg will be very wet at this point so...

Ditto to all the good things everyone has been saying about Kohala divers. On my next visit to Hawaii I will be using them for charters and rentals. During my boat dives with them I noticed a telling thing....there were local divers on board....to me that is an indication of the quality of...
Ditto to that. I dove with them in Feb 09 and also rented tanks and weights for my shore diving. Every time I went into the store I felt welcomed and valuable. Next trip I will be looking them up again.
On my boat trips with them I noticed something that I didn't see on any of my other...
@mayday1234....the fear seems to be strong in you. I suspect that you probably haven't given the position paper a fair read. Check it out here...ARSBC Position Paper. Most if not all of your objections have been addressed there.
In reality, after the initial novelty wears off, the amount of...
