Definitely not. You need to feel that the position of the fin is correct and you can’t do that without fins. I can back kick (just barely) in bare feet, but my technique, especially foot position and angle is much different than with fins. Practice really slowly and concentrate on feeling that...

The Fourth Element size chart has incorrect conversions from Inches to Cm. Not sure if that helps or not in your case. If possible I’d definitely try out a Proteus II Small Tall. I’m 187 cm, 85kg and the Large fits me very well. The arms and legs are very slim cut and take lots of pulling to...

The Suunto app just decided to update or possibly just recognize that my core was updated. I was able to get into the customization screen, but didn’t see an option to display Surf GF

They are in1% increments. Low has a range of 10-99%, High range is 50-100%.

As far as I can tell no. It looks like the IOS app hasn’t caught up with the new firmware yet so I can’t get into customize my display setttings. They did post a new v4 manual even though the link to it still says v3.

It will never lock me out in either algorithm since I will never skip a required deco stop. And if I did because of some emergency I’d probably take a few days off anyway. However, in Buhlmann it will never lock anyone out. I personally don’t think that’s a good criteria for picking an...

Eon firmware 4.0 dated Dec 19, 2024, includes the Buhlmann GF 16 algorithm for the Core models. This was previously only available on the Steels. I’ve just updated mine with Suunto link; it took about 20 minutes and the choice is now in my menu. I’m about to select it, restart and see what...

Has anyone got details on how to apply for the retiree waiver? Anyone done it successfully?

I did a week on the Infiniti and highly recommend them. Very safety conscious and were very good at grouping the divers into similar skill and air consumption levels. The boat is extremely well built and rated for any sea conditions.

Having been with many divers who lost cameras; the first insurance anyone should get is a secure tether that stays clipped to a D ring any time you are close to the water.

Nope, Horse Collar. Manual inflate plus a CO2 cartridge for emergency. BCDs existed but only as pictures in magazines. Same with Alternate second stages. In the words of my instructor “Those are for rich guys, and you’re not rich” Many regulators only had 1 or 2 LP ports. I remember an ad in a...

Nope, they were in general negative and had to keep moving and kicking to stay off the bottom. I took my original training in 1979. We worked very little on buoyancy. Skills were on our knees.

Very interesting, I immediately tried looking up my local currency but your calculator doesn’t include Canada.

Not about these regs in particular, but I find the bulkiest items to pack are the hoses. You could probably save a bunch of space by disassembling the regs before travel - though the most I’ve ever done is take off my dry suit inflator hose and replace with a plug before heading to warmer...

I never thought I’d use a quote from @happy-diver in one of my classes but this one I love! I’m going to use it on the next diver I see that goes totally limp and descends butt first, feet up until their tank hits the bottom. Also to the OP: whatever you finally end on make sure you have...

Definitely a hard decision here. It would make a big difference if I was guiding the in trouble divers or if I was just another diver on the boat, there to see the pretty fish. Just another diver myself: I’m doing whatever is safer for me. I might also be against you trying to swim to get them...

I’m not the OP but am an instructor and formerly a lifeguard and lifeguard instructor/examiner. I’m also a very good swimmer. You don’t want to turn 2 victims into 3. Not being there I can’t know if I would have judged the conditions too risky to attempt to swim to them, but it certainly...

I’d give the two points mentioned in your final paragraph much higher priority than your take away list. Stay close to your buddy Or Carry a pony or other redundant gas supply

Actually, the reason to adhere to the deco guidance is to prevent injury or death. This is still the case even on computers that will not lock you out if you happen to survive. That said showing an NDL at 6.5m, assuming the OP had been there some time or at least ascended slowly to that depth...

My scuba pro LP hose fits both my Scubapro and Aqualung BCDs, but my Aqualung hose will not fit my Scubapro BCD. The nozzle on the Scubapro BCD is about 1mm longer.
