yes I am aware of that, but thanks for clearing up any confusion that others
may have had.
Still I am interested in how many companies actually make this stuff.
While companies may own the designs for their regulators, there are many manufacturing specific issues that can come up..
how many companies actually manufacture regulator first stages?
Seems i read somewhere that only a handful of companies made most of the
first stages sold worldwide.
they are really not that hard to make (for anyone that can cast/forge
brass and bronze, has a multitool machining...
Awesome
I find this report very encouraging.
Diver called the dive, a bit of discussion and then headed out of the 'pool'. Lots of support in the water, when you noticed her gone. you, asst instructors and nearby divers join in. The various DMs and others performed rapidly and...
brass/bronze..
brass is copper and zinc
bronze is copper and tin
Brass, in all grades is unsuitable for seawater -- the zinc leaches right out. may take a bit. but the material deteriorates. you are left with (mostly) pure copper, which is soft.
Bronze, well it depends. some bronze is only a...
What to take for safety gear kinda depends on the dive.
I dive shore dives along the ca coast and boats in monterey with some (small amount of) gear, boats in catalina with more, and on a trip to palalu (several years ago) a whole lot... Monterey dives are in an area with much activity...
Few years ago i had a dive computer fail suddenly on the last day of a multi day live aboard. Missed the last dive, because of lost deco info. so now on live aboards i dive two computers (on all dives).
guy onboard told me that was all wrong, i was 'wasting' a computer. just use one the first...
My dad was an expert carpenter. He showed me everything. When he died i inherited his tools, and added some of my own. now i have all the tools and know how to use them. but i never spent the time practicing to be really skillful. Now i can build stuff, but its always off just a bit (and getting...
Hopefully one of the MDs on this site will chime in on this, but in my first aid classes, we were told to only use 1 of 2 topical antiseptics on an open wound, either Povidone-iodine or Quaternary ammonium compounds (such as benzethonium chloride, found in Bactine). All such compounds will cause...
I use my pony (19, 30 or 40 cu ft) if:
- diving over 80ft
- diving with a buddy that i don't know well
- diving with any of several paranoid buddies
- diving under kelp, or any other obstruction
this takes care of almost all of my dives except training/checkout/refresh...
I bought 6 regs off e-bay, 2 brand new apeks (from a brick-and-mortar dive far from me) and 4 used scubapro mk10 with g250 or g295 seconds. All were professionally examined and rebuilt as needed. The new ones needed nothing... the 4 used regs are set up as pony/stage bottle regs. All have...
I went through the process of selecting a mount for a pony bottle recently.
I tried three options: a 'pony tamer', pony bottle bag, and a diverite sling setup.
I really liked the idea of the pony tamer but...
I boat dive often. they provide the tanks. we switch tanks between dives...
Over the years i have heard several reports on this.
Air force and navy searched extensively and didn't find it. Used all kinds of (at the time) high tech stuff to look for it. Ten (or so) years ago there was another search, using newer stuff and trajectory prediction software. No joy.
The...
