I have two Halycon BC's both with butt dumps and never have used this method , dumping air out of my shoulder manual inflator with left hand held high . Since not using them cave diving , I should convert them to a shoulder dump . I wonder if Halycon has parts to plumb into the manual inflator hose or something else . Good Times. Rumdumb

@Eastwest,
My very first BCD was an orange taco-pocket-style SP Stab Jacket (SSJ) I purchased new in 1987. It had a single over-pressure relief valve (a.k.a. dump valve) on its right shoulder.
I replaced that SSJ in 1993 with a black classic SSJ, which has a right shoulder dump valve and another dump valve low on the back. So, this "new" SSJ has two (!!) dump valves that can fail!
I am fine with the single dump valves that each of my wings has. Truthfully, for the recreational diving that I do here in MO and AR, I rarely use any dump valve during a dive. Rather, I most often use the low-tech approach of dumping air through the power inflator or AIR 2.
FWIW.

It sounds like a bad ideal to me, but if you want to do it, Remote Exhaust Inflation Assemblies. (Why would you want to ascend vertically in the first place?)
Sorry to be a princess, but I don't like having to roll to my right and go slightly head down to vent from my wing. I put an inflator "pull" dump valve on both my warm and cold water wings. I don't need to break trim, and since the inflator is bungeed to my left "D" ring, I just give it a gentle tug. An additional benefit for cold water is that the exhaust bubbles are closer to your hood and you can hear them. No way when I'm wearing a 10mm hood can I hear the wing butt dump
OP
I ascend on a 45% angle most of the time because l have a load of gear , big scooters , big reels and game bags hanging from my side besides the anchor line is on a 45
@JohnN ,
I always recommend against an inflator pull-to-dump valve. If you pull on something, you just might pull it apart!
My SSJ has a pull cord leading up to the right shoulder dump valve. We were taught (in my NAUI/YMCA open water course in 1986) to NOT use this pull cord--because the cord (or its attachment point) might break just when you really need it to work! Instead, if we needed to dump through the shoulder dump valve, we would reach up and back for it with our right hand and directly trip it.
These days, I dive wet in at most a medium-thickness wetsuit with an old-school PST 72. Recreational profiles. I don't put a lot of air in my BC (whether SSJ or wings), so I don't need to be doing much exhausting.
