HOG 38 v. 58

[mathauck0814]

Looking at doubles wings for a set of LP85 tanks. Specifically between the HOG 38 and 58 # wings (not interested in other wings at the moment so please limit feedback to those two choices).

Diving a SS BP with SS STA and LM 21W can light, and potentially an occasional 40cf deco bottle in a whites fusion drysuit, would the 38# be sufficient lift to account for catastrophic drysuit failure or would I be left wanting more oomph from my wing?

LP85 are -7lbs full, add SS BP (-6lb) and you are at -20lbs at this point. Add about -6lbs for regs and manifold, you are at -26lb.

At empty they are close to -1 lb. So you have about 13lbs swing to account for and you are at -13lbs. How much do you need to sink you in your drysuit? If more than 13lbs then you will need to add that in led and this will add to the above -26lb.

You don't need STA for doubles.

Right (duh). Sorry, that's what I have for my singles setup. You're correct that I wouldn't have that in doubles. Dove this last weekend in fresh water with 6lbs of lead (in addition to the BP rig). So it could be pressing right up against the ~13lbs you mentioned in salt.

As Tobin always says, your wing has to do two things -- float your rig at the surface, and compensate for a disastrous buoyancy loss from your suit. I can tell you from personal experience that a 38 pound wing WILL float LP85s at the surface, with a can light and steel backplate.

With respect to your dry suit, how much weight does it take to sink you in it? If you add that to your 26 pounds negative that iztok is calculating, you'll know just how negative you could be at the beginning of the dive with a fully flooded dry suit. (In practice, you never actually lose ALL of the lift of the suit, even with a complete flood. Unfortunately, I know.) Subtract the wing lift from that figure and look at the result -- if it's more than 10 lbs, you may be in trouble if you have to swim up your rig.

A 58 pound wing will be much larger than you need, and probably will be annoying to vent, since the small amount of air you need compared with the capacity of the wing, will end up "taco-ing" the side pontoons.

I was diving a HOG 58 with LP 85's this weekend. Also carrying a 30 cu ft stage and at times my GF's 30 cu ft stage as well. In addition to a Salvo 12 watt rebel. I sell the HOG wing and frankly for the set up you described I would hesitate to go to the smaller wing. On the St Lawrence I saw a number of people diving with twin 40's. The 38 would be great with those. I'd also consider it with my dbl 72's or al80's. The price of the 38 and the 58 is the same so for the peace of mind and the reality that if you decide to go to bigger tanks like 95's the 58 will be more than fine for that.

If you want to save shipping on the wing visit my web store and ask for a quote on one. I am an authorized HOG dealer.

As I said I was diving the wing this weekend and there was no venting issue. I also found zero taco effect with my 85's. the wing was a little wider than the tanks themselves but so was the DSS LCD 50 that I sold when I went with HOG.

Check out the description on the HOG page or on my page. Chris from HOG/Edge is a NAUI technical course director and based the design of these wings with that background. If you are heading in the tech direction consider that at some point you will be adding stages and perhaps bigger tanks.

I dive HP119 doubles and have aforementioned 58lb wing. I might have been good with 38lb but to be honest I just didn't know better when I got the wing.

This is a picture of me (FB) from yesterday in my mostly HOG/EDGE gear. (wing, regs, hood, gloves, SPG, mask and strap)

I have HP119 and HOG 58 wing.

Thanks guys, I think that answers the question. At the same cost I just wanted to pick the better piece of equipment. It sounds like I'd be diving at or around 100% of the lift capacity of the 38 so the 58 would be better (wouldn't it be nice if there wasn't such a large jump??). I'll look around and see what other options are in the middle but with an eye toward the 58 (I have the HOG singles kit which is why I figured I'd look at their doubles kit, great stuff).
