#askmark I would love to dive in Winter too, I don’t get cold quickly. But I would love to know which would you recommend: semi dry, neoprene drysuit or fabric?
Most divers here in the UK bypass semi-dry suits and go straight to drysuit training. Drysuits have more flexible temperature ranges and they’re more practical in the water.
Membrane suits tend to be the most popular today. Neoprene drysuits do have their benefits but, membrane are lighter, less buoyant and tend to suit most divers needs.
Lift bags are also handy as “hang outs” on deco stops
No sure I found that explanation convincing.
Lift bag for lifting treasure; DSMB for telling the boat where you are if you can’t come back up the shot/deco trapeze.
Most tech divers DO NOT carry lift bags.
#askmark I have a Hollis DSMB ( the one that comes with it’s own carry case you can attach to BCD ) If I remember correctly, it has a lift bag rating as well. Are there many DSMBs that can have that dual purpose?
I suppose any dSMB can technically be defined as a lift bag, they’re just not designed to bear loads so you might strain the stitches. And the dump valve is usually quite low down so you don’t have great control…
I can’t remember seeing too many ‘dual-purpose’ dSMBs. I think it’s just some larger capacity dSMBs can be used as a lift bag in a pinch
BRING BACK THE BOLTSNAP TSHIRT!!!!
He is not in same company as before
@scuba cro ok….. They can make a different one… I was just suggesting..
I still wear it from time to time, just not in front of the camera. I’ll see if I can create a new version…
@Scuba Diver Magazine no worries, you are a great person thank you for all the information you give us. But… When I see a double ender I always think of your shirt lol. Have a great day
Hi Mark, how do you prep diving masks with a UV coated lens to prevent fogging? Can I use the same techniques for cleaning clear lenses such as using a toothpaste or the lighter method? Not sure if I do it the same way will damage the UV coated lenses or not. #AskMark
You need to be very careful with treated lenses. The best option is to ask the manufacturer of the mask for their specific recommendations.
The traditional toothpaste and SeaBuff treatments can scratch UV coatings and sometimes even the glass itself. Whenever you’re treating a mask it’s important to do a gentle spot test in a corner first before you risk scratching the entire lens.
Pop the manufacturer a message on what they recommend for your particular mask and they’ll know what’s best to avoid damaging your mask.
