That's a valid question but fortunately, my Horse Collar BC has the same "controls" as a more modern BCD. An overpressure purge valve and a pull purge in the corrugated hose. The only real difference in controls, is that mine has a CO2 trigger inflator. However, unlike most of the other inflators, mine is in good shape with a new cartridge, the safety wire clipped into the trigger and the pull ball is up under the pocket flap. I've heard of them being popped off accidentally but it never happened to anybody I knew.Something to consider: Will anyone diving with you (or near you) know how to handle your gear during an emergency? Does this matter to you?
A few years ago, I began diving a double-hose regulator (a U.S. Divers DAAM that had been upgraded with a 1st gen VDH Phoenix nozzel). Eventually, I added a second stage (a Scubapro Balanced Adjustable) to my DH reg. Even though I dive solo almost exclusively these days, I nevertheless decided that having a typical "safe second" available for anyone who is unfamiliar with buddy-breathing using a DH reg, is prudent.

Nah, I wasn't a badass but I was in better shape than I'm in now! Even so, I cheated a little carrying my tanks up the ladder. i would set them down on the next step, go up another step, lift them up a step, etc. etc.If you’re that big of a badass why do you need any sort of BC at all?
Just dive like these guys, cold water in 7mm wetsuits, no BC backpacks only diving to 100’ chasing bugs and Halibut. Even the gals can do it!
I doubt too many of them had to lug twin 72’s up a high dive and then jump off and put everything on while being harassed with a blacked out mask.
There's a few up on Fleabay right now but plan on a full rejuv! The bladder in mine is still in excellent shape but I've heard you can make your own from the same stuff waterbeds are made from. There's one company that I found that makes new ones but they're black only. I like bright colors. I have actually considered buying a cheap leaky one to disassemble right down to the individual pieces of material so that I can duplicate it with newer material.I wish they were still around as much as they were, Easier to dump a belt, than get those pocket weights out. Easier to take the tank off too after existing the water! I'll keep looking and find a great combo!
I'm going to try explaining a lot of entries to this thread. In saying this, realize that in the 1970s I was actively trying to get a different front-mount design out into the diving community. It was rejected by several companies. I called it the Para-Sea BCD, and it answered all the questions you pose above. I patented it, and this allowed for the separation of the BCD from the Scuba unit. It provided pockets to allow the air to travel from the neck to the pockets, which were close to the center of gravity of the diver. I patented the Para-Sea concept, but had no takers.How often do you drown compared with diving with the thing?
A BCD needs to be on your back (assuming backmount) so you're more stable in the water.
A wing is best for being flat in the water.
A front-mounted BCD will be unstable if you've a lot of variable weight, e.g. multiple gas cylinders (or considerably larger volumes than was common in the 1950s), heavy reel+SMB, etc.
In other words, innovation made horse collars unnecessary as there's better technology. Do you use a slide rule or a calculator?
If you find an old AP Valves one, send it to AP and they will give you a refurbishment cost. It will come back like new - except for the faded colour.There's a few up on Fleabay right now but plan on a full rejuv!

They still live on in the form of the snorkel vest.I still have two Seatec Sunfish horse collar BCs. One is NIB in reserve, the other is in fine shape and I use it from time to time. I enjoy the large front pocket, I disarmed the CO2 cartridge. And I will interject right now, popping the cartridge at depth is a non-event.
I use the horse collar for warm water shore diving where a swim out and back might be required with snorkel assist, example of a place I use it at, St Andrews Jetty State Park in Florida or the Destin Finger Jetty or Commercial Pier shore diving Fort Lauderdale. Since I am in minimal exposure suits I need minimal lead and thus getting a good trim is relatively easy as little or no air is entered into the horse collar, basically as if diving sans BC but with flotation assist for the swim out, back or if I get tired, lol. When you young folks get older and you will get tired occasionally and want to take a nap or at least catch your breath for a bit .
As soon as exposure protection suits are added, lead is added and the horse collar sucks as it tends to rotate me head up and level trim is a challenge.
For most diving that needs a BC, which is not all diving, a wing and back plate rigged single tank or multi-tank Hog is far superior. Level trim is easy regardless of exposure suit, none or a full suit, the wing is the thing! My first wing was Scubapro circa 1976, I also have had and worn to shreds two Seatec Seahorse wings. Then called back inflate. They were wings.
