- Part 1 of this series, how to read your instruments. The SPG mostly used reactively by keeping an eye out for when you reach the minimum pressure you planned for. But what if there is a way to know what your SPG will say before you look at it?
Here you can see parts 2 and 3

Thinking in bar/minute. You can train/learn that also by experience, notice your divetime and see how much bars you have used for that size of bottle (keep also in mind the everage depth..). For me roughly it's 1bar/min on a 12ltr, diving in the netherlands, so at about 10-15 meter depth.
This by far is the most useful info/guide I've seen from all the other dive videos. Thank you for this!
The T formula us our most valuable tool,many divers did not know about it and is valuable for field math
Great way to show that the SPG is there to confirm what you already know.
Many thanks for this video guys! Excellent!
1. Great presentation style. Love your mix of calm, little jokes, and serious!
2. Love the idea that gauges should be confirming what we already know.
3. Important point that math like this takes TIME & PRACTICE.
4. TOTALLY FUNNY that you low-tech paper taped to a high-tech monitor. Totally illustrative of the point of the video!
5. I do find it a little strange to assume that your watch (time) and computer (average depth) will keep working but your SPG won't. I mean, if you need time & average depth numbers from your gauges then you are still relying on your gauges. IN many cases (like my own) my time & average depth are on the same air-integrated computer as my SPG. And yes, I can guy backup gauges & computers.
5A: To be clear: I still find immense use in the notion of knowing all this in your head, by feel, by intuition and second nature after a while. I think the ideas are great. I'm just saying, it need to be acknowledge that, as presented, we're still relying on gauges.
Thanks! Great video! Keep 'em coming!!
Very interesting and crystal clear explanation. Thanks for sharing!
Great video Ben as always.
Glad you enjoyed it
Brilliant video I’m using it now cheers makes life simple.
Surrounding pressure minus 10% per minute for a D12. That's some useful info.
Awesome video, thanks for this 👍
Top content!
Great video ,thank you
Our pleasure!
Thank you for another learning opportunity
Our pleasure!
So on the Bar/minute consumption can I just use a simple conversion for Bar -> PSI to use with my PSI spg’s? I have that one BAR pressure is equal to 14.50377377 psi.
