    First stage IP and dive below 100m

    Hello, If I am not wrong our standard first stage give an intermediate pressure of 10bar to the second stage. I’d like to understand what happen when you reach 100m or deeper so that the IP is below the ambiant pressure. Any reference to articles would be great as well. Yvan

    Trip Report Gozo

    Regarding diving Gozo sites from Malta, it is very easy as there is ferries between the two islands. I am always based in Malta and go for day trip to dive in Gozo. If you are around Valeta, you have 30 minutes by car then 25 minutes of Ferry. If you have just one day of diving, go for the...

    Is heart attack necessarily the end of diving?

    Hi There, Not sure if I post at the right place. I have a colleague that had a heart attack while doing Jogging one year ago. Despite this incident, he was in pretty good shape, I mean no particular issue as far as health is concerned. Now, he ask me if there is a possibility to come back to...

    Underwater video setting / Video light

    Just my 2 cents from photo experience. Your WB should match your light source. It is the way you tell your camera how to interpret Colors. U/W will work fine in the shallow and ambient light. Once you'll switch to external lightning you will need to change the white balance. You most probably...

    Backup Mask - Ever Had to Use While Solo?

    You could probably say the same for any back-up you carry. Personally, I prefer to have a back-up mask that I don't need instead of needed one that I don't have. One thing is sure, your strap will break, (your main reg too) the question is when :) So the point, is can you afford of not having a...

    Let's Hear about Your Bad Training Experiences

    This course is clearly where you need an Instructor that have really something to teach. If you go anywhere and you are already a photographer or fan of photography, then that is clear that you will be disappointed... Same apply to many specialties like Wreck, Biology and so on.

    What is your personal "Helium" Depth?

    If he is PADI Tec Deep Instructor, he will find the answer in the standard page 6-62 :) So there is a possibility of using Trimix on the last dive that is below 40m (130 feet).

    What is your personal "Helium" Depth?

    Rainer, let me clarify because there is 2 points here. 1) I dive with friends and we are all certified Trimix, then I will tend to limit myself to 130ft END. 2) There is course structure where at the TEC50 level (kind of extended range), the students are not certified Trimix, that's why I...

    What is your personal "Helium" Depth?

    130 feet if open water, good viz and no penetration. In a very cold and silty quarry, with very bad viz (1m) I raise that up to 80 feet. I teach Air down to 165 feet on Air (PADI Tec 50) but I clearly explain that this is before the student move on to Trimix (temporary step).
