    Looking for Eco-Friendly Ways to Clean Dive Gear

    You do a lot more damage traveling to a dive site and compressing the gas. Fill your rinse tub, do what needs to be done and dump it on the lawn.

    Safety margin of backplate/ wing if drysuit floods or other problems ?

    Getting out of the water is where the real fun begins. it happened to my wife on a shore dive and we had break her down and doff the suit in the water. Having witnessed her situation I can't imagine getting up into a boat wearing a truly flooded suit.

    Cleaning BCD

    Great point, I rinse the bladder 3 times and do the inflate circuit on the final flush. Since that part of the valve sees mainly air I try not to inundate it with any more salt than necessary. If I fill it just right it will create a venturi effect that inflates the bladder as it fills perhaps...

    Stage Bottle or Backmount Doubles

    I'm nearly an exclusively a single tank diver. I do have a dive or 2 where I want a lot of air. For those rare occasions I have slung an AL80 shoulder to hip diagonally and it worked really well. Jumping to doubles or side mount for my infrequent need wouldn't make any sense at all. If you go...

    Neoprene wetsuits and Sun protection

    When we spent a week in Bonaire I was surprised by the burn I got on my legs between my shortie and boots just with incidental exposure between dives. If you can beat the heat and have fair skin keeping covered in the tropics makes sense.

    Trim weights

    Change with purpose.... You need what you need so set yourself up with some smaller weights adding up to your exiting load. At the end of a future dive when you are wet, your tank is down low and you are about 10 feet of water with an empty BC see what you can live without to stay down. That's...

    cold water exposure suit debate

    I have a Bare Reactive and it is a nice suit. it's only as hood as the weakest link and on a full suit it is the neck opening.I have a hard time saying it dramatically better than the 12 year old Arctic it replaced though the arm and leg seal systems are slick. I wear the hooded step-in vest and...

    Going from AL100, salt, no wet suit ---> HP100, fresh, 5mm... advice please.

    My best answer is that I would think so. Assuming you are correctly weighted as described what is it that you need to swim to the surface? 1) 100 CF of air weighs 8 pounds. 1 pound or so is factored into being neutral so an incident at the start of the dive offers 7 pounds of unbalanced...

    Going from AL100, salt, no wet suit ---> HP100, fresh, 5mm... advice please.

    I assume you meant (about 5 lbs more negative than an AL 100 when empty) An AL80 is ~4.4 pounds positive, The PST/Worthington Steels about 1 pound negative. That is ~5 pounds more negative than an AL 80. Faber has stuff ~6 pounds heavier that the HP100's I cited that is ~6-7 pounds negative.

    Going from AL100, salt, no wet suit ---> HP100, fresh, 5mm... advice please.

    38 pounds of lift is more than enough so you're good there. The empty buoyancy properties if the AL100 and HP 100 are very close with the HP 100 being about a pound heavier depending on brand (PST, Worthington) and specific cylinder. Some Fabers can be considerably heavier. Again it is the...

    Curious Question - Wave action compared to ATA

    That IP air is at pressure when it is contained, i.e. in the hose. Once it gets past the remand valve the velocity increases with expansion and there is some locally higher pressure as it diffuses in the case but this is in no way full IP. What you represent as full IP is more like force, the...

    tank fill rate

    The 600 PSI/ minute number is common. I think I have seen CGA guidance more like 300-400 PSI/minute. SCBA rapid refills have become quite common on the order of 45 seconds for aluminum and composites. See here. I have a LDS that ca do a 30 second fill. :( Pete

    Weight placement

    Personally put it all on the belt except for weight that needs to be higher up for trim. I dislike dealing with a heavy BC.
