Rear Dump Valve or Inflator Hose Dump?

[tstormdiver]

Rear dump. It is the most convenient. I rarely get out of the horizontal position, even when teaching students.

I was talking to a friend who said he never used his rear dump valve on his BC/Wing, that the rear dump was only an OPV. Me personally, I frequently use my rear dump as opposed to my inflator hose because to use the inflator, you have to right yourself.

What do you do, and why?

I use rear dump almost exclusively whether I'm in my single rig or my doubles rig. At the surface on the ocean dives, I may use the inflator hose to dump but once I'm under the surface, it's the rear dump for remainder of my descent and my dive. I use the rear dump because it's easier to control the amount of gas I'm dumping from my wing, at least, it is for the way I dive.

I use both of them randomly on ascent.

Almost always use rear dump.

I mostly use my inflator hose. I dive with my hands out in front of me, and it's a very short distance from there to the inflator, but a much longer sweep backwards to the butt dump. If I am carrying additional tanks, I have to get my hand between them and my body to reach the dump. Because my wings have a fairly large upper arc, there is always gas available to the inflator without changing trim much, if at all.

The one time I used my butt dump a ton was when I dove wet in Mexico. For some reason, it seemed really easy to do it then.

I will use both as the situation dictates (going up hill on a scooter and I use the hose, for instance). My default is to use the rear dump, however.

inflator hose at the beginning of the dive, mainly because I'm floating upright at the surface, after that its almost exclusively my rear dump valve.

I find the hose dump easier to control. I just hold it open and raise or lower it to control how much air I dump.

an effective "old school" technique which I highly doubt is taught anymore. where is Thal?

I seem to have "issues" finding the string on the butt dump with 5 & 7 mm gloves. I like using the inflator directly,or the pull to dump (shhhhhhhhh!) that I have depending on how I need to execute.

what ever valve is at the highest point ....

I dive a horseshoe wing without a crossover, and I actually added another butt dump to prevent having to roll the wing in a horizontal or head down position to trim.
