So ssi will recognize that card and they can give you a digital card of it. The reason they won't give you a new ssi card is because you haven't done an ssi course, simple as that. But you can get the NASDS card online in the ssi app. What you should do is email your local ssi rep with a...

21 years old. Certified beginning of 2020 and about 600 dives

https://www.backscatter.com/Isotta-GoPro-HERO9-Underwater-Housing This one will do 200m 600ft and you can see all the screens. Some of the deeper ones you can't see the screens. And in this link you can see a whole range of options. Remember that the 9, 10 and 11 are all the same size and can...

10m without case. 60m with the gopro case and up to 300m with a custom metal case. (10m~30ft 60m~200ft 300m~1000ft)

But it's not??? @LandonL

It's obvious it wasn't in his hand then isn't it? Not in his hand - not relevant Something caused the gun to go off. In my experience of cheap guns with no safety, hitting the butt on a rock could cause that and would also solve the recoil problem. Now that is utter crap. A small gun is...

You worry about some people having to replace a 150 computer by making everyone buy a $500 computer. Barely anyone goes tech, let them buy a proper computer then and use the original in gauge mode. The mares Puck is as easy to operate as a shearwater. One press to cycle long press to select...

Does it? The website certainly doesn't reflect that. Deep 6 Excursion Dive Computer

Tap in the location box to type in a new dive site. Then just paste the coordinates from the subsurface map into the box. Done

Have you fully read the manual yet?

They do not use it because of helium shortages. It is used in very deep commercial diving to allieviate the concerns of HPNS from the high pphe but it can't have more than 4% oxygen or something otherwise it can ignite. Correct me if I'm wrong

For ean40 you need to compete the second final exam of the Ean e-learning as well as the first one. Also while science of diving does cover a lot of the theory it does not cross over. Then all the relevant analysing, marking tanks and setting computers in person. I don't believe you have to do...

Welcome from Picton! What are your local waters? Depends what you consider warm haha! Top of the north island gets a couple months of 20c+ each year.

Basically the dive number on a verified dive tells the app and awards how many you have. For example when I crossed over to ssi I sure as hell wasn't going to input hundreds of dives into this new app and verify each one. What I did was input my most recent dive, number it as it's correct number...

Too right. Correct that's why we talk about the economy of a car not the consumption rate (here at least) Perhaps but I still feel multiplication is easier than division. Unless I'm just doing the wrong calculation?

Actually it's usually litres per 100km. My car for example get 6.5l per 100km. That's pretty good because it's a small hatch back. Now the reason we do it this way instead of miles per gallon is because multiplication is easier than division. If I have a trip of 500km then I multiply 5 x 6.5...

This is what it looks like on mobile. Not very easy to see especially zoomed out.

A little tag next to the name of the original poster that says op or original poster. Like how yours says staff member.

The average diver doesn't do decompression let alone accelerated decompression so I'd say exactly zero litres. OK joke over. It entirely depends on where you are, round here I've never seen anyone use 100% it's usually between 40 and 70 percent. And rarely longer than 15 mins.

In case you didn't know cylinders have different rated pressures that is defined by the structure of the tank NOT the gas that is in them.
