    Differences Between UTD and GUE

    When you guys take your average depth, are you including the descent portion of the dive? As far as I am aware the Uwatec bottom timers can't be reset once you hit depth, unlike say a UWATEC TEC 2 G in gauge mode, where the average depth can be reset. I am not a DIR diver, but I have been...

    How much Nitrox is too much?

    Thanks for all the replies guys, I was thinking in terms of OTUs. Yes you are very correct about the profiles not being square, especially here in the northern red sea, where pretty much every dive site extends from just below the surface to anything up to about 800 meters at our deepest walls...

    How much Nitrox is too much?

    Hi there, There is a question I would like to open up to discussion regarding Nitrox. I am a full time diving instructor and dive guide. For me this means that I do about 50 to 60 dives a month on average. I will normally dive for 6 days during each week and have one dry day, but...

    Post Dive Dizziness

    Dive Rite gear setup

    Hi there, I am about to buy some gear from Dive Rite, but as I have no access to a Dive Rite dealer I am ordering the gear and will have no chance to see it before I buy. Size will not be an issue as I am not ordering anything size specific, but just wanted to double check that I have all the...

    Drysuit Undergarmets for "warmish" water

    Hi there, I am looking for some advice on undergarmets for a trilaminate drysuit. The suit will be used in temperatures between 20C / 68F and about 24C / 75F. I know these temperatures may not sound cold, but when you consider that I will be diving in them nearly every day, 2 or 3 dives per...

    Mimic Octopus in the Red Sea?

    Is it possible to find the Mimic Octopus (Thaumoctopus Mimicus) in the Red Sea? Because there have been a few reports of them being sighted in Sharm El Sheikh. They look the same as the photos I have been able to find of the Mimic Octopus in the Western Pacific. I saw one the other day doing...

    Ras Mohamed & Tiran straits Jul-09'

    Shark and Yolanda is amazing in the Summer. Well acctually its amazing all year round, but June/July/August is the best. I could dive there a million times and never get bored of it (and I dive there at least twice a week!) Glad you had a good time, when I was working in Mexico (Yucatan) we...

    Lost Buddy Marker

    Not a cave diver but still very interesting reading this discussion. I know that some of you have GUE training, don't you guys normally dive in a team of 3? I'm just slightly confused because everyone is talking about them and their buddy, but in a team of 3 where would the 3rd person come into...

    Why Aren't Dive Tables/Computers Customizable?

    Speaking of "inexact science" what you also need to consider is a number of things with regard to the acctual pressure on your body during a dive. You need to be completely horizontal during your entire dive for your whole body to experience the same amount of pressure. A lot of divers spend...

    Is it time to sink the CESA?

    So you expect people to get certified without the ability to make themselves neutrally buoyant? I think hovering is pretty essential. I mean imagine you stop swimming for a minute to look at something on your dive, how to you expect to maintain your depth in the water, by kicking continuously...
