Obviously there's more buoyancy in the suit before you sink. You may have added additional weight to counteract this. More weight needs to be counteracted by more air in the drysuit/BCD, especially if changing depths and more so if doing shallower dives.
Since when did a certification ever prove competence?
Thank you for showing us your card. Now do a checkout dive to demonstrate your skills and prove your competence.
BTW why do you have to be instructed to do or learn anything different? Put up an SMB - we have a speciality course for...
This, of course, is a wind up
Only a Revo diver would have 90 degree bailouts, lousy finning and rubbish trim. All other divers are perfect in every way and talk utter bollocks about a unit they know nothing about.
Hey, lets enjoy our differences. No! Be part of the borg, we have cookies.
Alas, that's what you get in the dive resorts; 3 or 4 days and buy a pack of dives for the rest of your vacation. So easy to "master", what's so hard with that?
It's quite some shock when you come to realise that diving's not like that everywhere.
And Revo added a Nerd because it looked good and was something to connect to those spare cells.
It is pretty neat to see at a glance all five cells. You learn their differences and reaction times. Obviously that’s if you prefer running the unit manually with the controller as a backup at a...
Point is more that a typical OW instructor would need to do a lot of work to get to the standard and practice required to be good with twinsets. If they're diving OW all the time, the skills are somewhat different.
And then there's the raw novices at the beginning of their diving careers, trained to follow-the-leader.
Have often wondered about the differences between conditions and whether or not this effectively constitutes a "technical" dive. Thinking that in the benign, clear, warm waters of some...
It's not about wasting Sofnolime, although it is a nice side benefit. It is primarily about safety margins.
I have no qualms about doing a couple of two hour dives without changing the scrubber. Similarly if I were doing deep wrecks ~100m on 4 hour+ runtimes, then I'd have no qualms about...
There are shore dives. But there is a fair amount of current too. Shore dives are much nicer in the north of the British Isles as the geology is more interesting.
Boat diving is primarily on wrecks. Lots of wrecks. Like thousands of them. Some of the wrecks around the Isle of Wight and...
You'll love the diving out of Swanage & Portland. Perfect for recreational depths.
And a dive under Swanage pier; the baptism of many a newbie diver. Literally walk down the steps and dive.
Most people dive drysuits all year round. Water's warm enough for a wetsuit from July onwards at...
The solenoid has its own battery and is also on the CAN-bus.
The unit comes from a manual background, so has an orifice (leaky valve) meaning the O2 levels slowly diminish. Many people (me included) run them as manual units using the controller as a backup, hence it's a "hybrid electronic...
