Proper wing size

Me and the GF are in the process of buying gear. We have decided to go BP/W. Found a good deal on some used stuff but worried about the wing size. The used ones we found were a 44# and #45.

Most of our diving is going to be in fresh cold water under 60* so we currently have (and will be quite sometime before we will change) have 7mm full suites with 7mm outers with 5mm boots and gloves. I am about 240# and she is about 160#. We dont have tanks yet but due to price (going to need 4 since dont live near a dive shop) we are looking at AL80's. No plans on doing doubles any time soon either.

We do plan on doing some traveling to salt water a few times a year. Half will still be cold water and half will be nice tropical places so I am sure we will have less gear on.

So will the 44/45# work or is that too much for what we want?

That one post will be worth the time to create one. Just be careful posting there, many advanced divers... They are territorial! but plenty of good solid info.

Doubles or not isn't an issue since you should have dedicated wings for singles and doiubles anyway

Also your body weight isn't a direct factor - how much weight do you have on your weight belts?

45# is probably going to be more than you need for a single AL80 but I'm not clear on what you mean by 7mm suits with 7mm outers... sounds like a lot of neoprene (and you should get a drysuit)

Here's a link that doesn't need a log in: http://www.scubaboard.com/forums/bu...ems/158370-ultimate-wing-lift-calculator.html

The short answer is that the 44#/45# wings are probably too large. Generally speaking, you don't need that much buoyancy for singles, and wings with that much lift are often too wide and will taco too much around your tank of choice. A wing that's very wide will make venting of gas more difficult that it needs to be.

Wing should do a few things:
1. Offset the weight of the gas in your tanks so you can be neutrally buoyant in the water
2. Adequately float you on the surface
3. Adequately float your gear on the surface without you
4. Compensate for loss of exposure suit buoyancy

Since you're in PNW and you're diving 14mm, point 4. would be valid reason to get a large wing. At 60', your wetsuit isn't as buoyant as it was at 33', nor at the surface.

For the tropics, the 44#/45# will definitely be too large. It's diveable for sure, but very inefficient. But that's one of the benefits of a BP/W. Many of us of have small < 20# wing for tropical diving.

...it's something of an urban legend that a 40 lbs wing is 'tropical overkill'......not all wings are created equal, and my Oxy Extreme 40 lbs single wings are VERY streamlined (no dreaded bungies or 'taco-of-death syndrome) and they give me extra reserve lift for contingencies.

The 2 wings are DiveRite REC wing (45lbs lift) and Zeagle Ranger (44lbs lift).

I was not sure about what things were required for determining lift so I listed all I could think of. Dry suites are out of the question at the moment since there are 2 of us that means $2000-$4000. I keep calling the outer piece an "outer" but Bare calls it a "step in hooded vest", Dive - Products - Wetsuits - 7mm Elastek Step-In Hooded Vest - Men's

She was wearing 28 lb weight and I was at 34 lbs.

I am just worried about wasting money on a item that we are not going to be able to use. If they are useable without too much negative effect (size, drag, ect) then I feel comfortable buying them.

In the linked thread below, amongst quite a bit of other noise, you can find a fairly detailed discussion of several people's opinions regarding wing size (among other things). Personally I think the proposed wings are larger than optimal, even more so given the fact you plan on diving Al80's for your local diving.

Both of those wings are not very good for singles. The rec wing is a fantastic doubles wing if you have the older narrow doubles. The ranger wing is a funky wing and I would never buy one.
With a SS plate you'll negate the tank and a bit of the suit. The Halcyon 40lb wings are overkill for the tropics, but that doesn't mean they're bad wings. They're cut is really nice, and the same with the HOG 32lb wings. The Rec wing is wider at the bottom to accommodate doubles and tacos really bad. What you really should do is call tobin at deep sea supply and talk to him about wing size. You also should go to the pool with your wetsuits and do a proper weight check.
Have one in the pool fully dressed, and the other will add weights to a belt. Start with 20lbs and add 2lbs at a time until when they have fully exhaled they start sinking. Don't do this with any other gear on and that will give you the true amount of weight that you need to sink you and your exposure protection. Take that weight, add in about 10lbs and that's your wing lift. 10lbs factors in use of steel tanks which you'll want, as well as keeping your head above water and an extra 3lbs so you can float.
While you're at it, I know it's expensive but invest in steel tanks. You're throwing money away and throwing your back out by diving AL80's in that area.

That last one especially is worth the drive. Those will remove about 5lbs of weight off of your belt and give you almost 30% more air. The 8inch diameter tank will also help in the wing aspect because the wider tank will help minimize the taco effect.

That is a good 40lb wing. Call Edd and see if he can put some black friday package deal together for you since you're buying two backplate sets.

That is a good deal, not gonna lie. You get the DSS wings and plates which are kick ass, and John is a great guy to deal with.

Also good, but get the voyager wing from diverite if you're doing that one. Both are great quality.
