First dive with new BP/W

[tomboyy]

Well just got back from a sunday afternoon dive with my new DSS BP/W. Air temps 40-45 degrees water temp 70 ish.... diving the return at the nuclear power plant. those reactors must get hot to keep the water temps that high It's a pretty shallow dive 30-50 feet, I over weighted to start at 24 pounds ( really over) 18 belt 6 back plate.When it was over with I started dumping weight and ended up at 10 pounds in my belt and could hold a 10ft depth at 600 psi easy. Gonna work it some more next weekend and plan on doing the "grave yard" at Jocasse... where part of Deliverence was filmed . I found out a 5' primary is way to short... I can't remeber where I read that 5' would work and why but apparently it made sense when I was reading it. Going to 7' before next dive.I can also say that I didn't care for the 13 or maybe it's 15 inch, inflator... feels way to short and I can barely put my mouth on it and it seems like the inner tube that the low inflator hose goes thru would affect the dumping of air but I guess it didn't as I experienced no problems..maybe thats something i'll have to get used to or maybe I'll increase its length.. all for now.

Tom,

Glad to hear you are having success with your new rig.

IMO 5 ft primary hoses are not much use. I expect that you will find the 7' hose much easier to use.

The inner tube loop on the left shoulder strap above the Dring should be used for only the LP hose, not the corrugated hose.

Before making any changes to the corrugated hose make sure your plate and wing are correctly positioned on your back.

As long as you can orally inflate, the hose is long enough. It's common for new BP&W divers to find the corrugated hose "too short" Most discover after a few dives that it's "just right"

well that saves me a phone call - I was about to call about how that was supposed to work; I'm loving the new DSS bp/w I got - great product

5ft is fine provided you dont try to route it like a 7ft hose. It should go pretty much under the right arm pit then across to left shoulder and behind neck (as opposed to 7ft where its down to waist buckle or under a light and around).

Unless you're about 6ft5+ a 5ft hose on a single should be fine.

 

[tomboyy]

I did mount it under right arm around left shoulder like you described and it was way to tight.Might have something to do with having a chest thats 48-50 inches. either way 5' is to small.

 

[DA Aquamaster]

Yep, with a large chest you'd need a 6' hose and to be honest a 7' hose would not be too long.

Normally the extra hose goes under the can light, but as long as you are diving a BP/wing any extra hose can just be tucked in the waist belt on the right side even if you do not have a can light. The shorter 5 and 6 ft hoses really only apply to jacket BC's where you can't really tuck the excess in the waistrap on your right side because a strap, if any, is inside the BC.

Just get a 7 ft hose and call it good.

I agree with Tobin that the short inflator hose will "grow" over the course of a couple dives and will eventually feel fine. You need to be able to orally inflate (both on the surface and under water), but since you hardly ever do it that way it does not have to be super easy to do nor do you have to be able to do it while looking straight ahead.

My abroad single tank wing ive just gone back to 5ft as keep finding the 7ft wont stay tucked in the waist belt at all and has a habit of "self deploying". Its ok in my drysuit with 3 underlayers here though but the wetsuit is a bit more slippery.

Short inflator caught me out with my first wing but since then ive realised although shorter it is in fact exactly the right size. Using a longer one now just feels too long.

I tried a 5' hose with the DSS BP/W (not that it matters which BP/W) and I thought it was too short as well. I'll eventualy get a 7' hose. They're kind of pricey!

I'm still thinking about the corrugated inflator hose. It's probably long enough but the low pressure hose is way too long for my regulator and it pushes the corrugated hose somewhat. I ordered a shorter hose from somewhere but actually received a standard hose - not much help. If I could get a Miflex hose if might be a better solution.

You can get standard hoses of the correct length (and miflex). Not all dive shops will stock short hoses though - better off looking and ordering online.
