I'm a Fish!
I use a Beauchat Master Lift Pro at the moment but am interested in possibly moving over to a harness/wing BC. I will also be using this in the Pacific Northwest for drysuit diving.

Can anyone explain to me the benefits of a harness/wing BC over a jacket style? Is it needed only for tec diving, or can it be used for recreational diving also? Is a simple Backplate/wing/harness configuration best? Or the Trans Pac or IQ type harness type? Is it worth is to buy the SS backplate over the Aluminum even if I plan to mostly dive single tank to begin with? Do I need more than a 40 lb. wing for single tank use? Any info you could provide would greatly be appreciated.
Thanks
 
I honestly feel that the choice of BCD is a personal thing. I use a Halcyon BP/wing setup... after using jackets, and other bac-inflation BCs (all rentals), I decided to go the BP way with my very first BC. I'm very happy with it... although I found it quite expensive (US$550)

In my opinion, there is no right BC for tech or rec diving. Out of years of experience, most divers find certain needs underwater... these needs translate into the kind of BC you end up using.

I like the BP setup cuz it feels like Im not wearing a BC at all. Although I have had a need for pockets, and wish my BC had some... so that might be a drawback for some people... yes you can add pockets... and you should have pockets on your wetsuit... but that's not the point.

If you've never felt constricted by a stab-jacket BC, then I say stick with your current config.

The advantage of a BP setup is its modularity... you can just buy different wings for different uses ... single tank, doubles... tropical...or cold water diving.

Some BP manufacturers like OMS have a cross-breed... with their IQ pack... it's a padded harness with the BP slipped inside... it's quite comfy... some people like it, some don't. I didn't care for it much after trying out a bare BP underwater.

Basically, the BP wing arena is pretty much a DIY area. You can mix and match MOST (not all) parts from different manufacturers. A cheap SS BP, with generic webbing, Halcyon buckles, and an OMS 95# can be assembled if that's what you need. You can later change the wing to a smaller Halcyon 27 for singles... or get the OMS IQ pack if you want a bit more padding...etc...etc..

BP became popular since most wreck/cave divers use their tech rigs for OW dives as well... a lot of them liked the fact that they didn't have to switch rigs anymore... not for anything, but jacket BCs have more POTENTIAL problems in a tech environment...and are more difficult to service in the field should anything go wrong.

Thing of a BP and wings as an F1 car... streamlined, bare, performs well, not much comfort, but easier to repair in the field (have you seen them do a pit stop to change bumpers, spoilers, engine parts??? ;) )

Think of jacket BCs as an everyday sedan... plush, comfy, more drag than an F1 car, takes longer to service (must be sent to a shop) ... and actually, not as safe as driving an F1 car...even though public perception makes F1 cars seem more dangerous!

I know the analogy isn't perfect... but it's the closest I could think of. The F1 car is built around simplicity... they cannot compromise safety, or performance... just like a BP/wings. It may not have all the trimmings, pockets, and dump valves of jacket BCs, but then again, that's less systems to worry about.

The reason why jackets usually have a lot of dump valves is cuz they trap air... the air cell is an odd shape that in most positions, air gets trapped even when nothing more comes out of the inflator hose.

Anyway, I'm drifting... with regards to what plate you need... depends on how much weight you're using now... if you need way more than 8#-10#... then get the SS plate. If you're using somewhere from 4#-6#, you might want to consider the AL plate and just get additional trim weights.

Whether to get the IQ pack or something similar... or a plain BP... that's really up to you. :) I decided to go with the bare BP setup... if in the future, I decide I want more... I can just get the IQ pack after and use my same setup :)
 
I didn't ask the otiginal question but....your answer was very informative. How do your feel about the Zeagle Ranger / Tech? Based on their design and your views, it would seem like either of these would be a good compromise. I have been looking at the Ranger LTD. They are simplistic but still able to adapt by changing bladders, attaching a BP etc.
 
I have a Ranger (non-LTD), a DUI, and a Halcyon BP/Wing. Originally I thought about trying to use the Ranger or DUI with the various add ons for tech diving - looking back I'm really glad I didn't.

While in theory I have nothing against converting a recreational BC for tech use, I'm much happier in my simple bp/wing than my friends are who have done recreational conversions and/or used cross over bcds.

I know this is just an opinion, and I'm not backing it up with a lot of 'why' - please take it as just that.

The simplicity of a straight bp/wing is very nice.
 
I don't see anything wrong with Zeagle's new Tech BC / BP offering... unless it's more expensive than Halcyon's or OMS's rig. Then that would probably be it.

Honestly... it's a piece of metal with a balloon bolted to the back... how complicated can that be??? :lol:

Metal grade (resistance to corrosion)
Cordura nylon grade
Urethane coating grade

and basically over-all build quality should determine the rest... all the BP wing rigs should perform about the same... minor differences in hydrodynamics and streamlining shouldn't make THAT big a difference unless you're using an oversized wing.

IMO (remember, MY OPINION ONLY) as much as manufacturers want you to believe that hydrodynamics plays a big role in our diving, it doesn't. That huge thing we call a tank negates almost all our ability to slice through water.

Just like those Honda Civics people see with huge-a$$ tail wings... these wings do work... ONLY AT HIGH SPEEDS. Fact is Aero & hydrodynamic efficiency usually kicks in LAST in over-all performance... which means that at the speeds we divers swim at... hydro dynamics probably makes very little over-all difference.
(keeping your junk from dangling around, wrecking corals, and getting tangled however...that's another story)

Swimming at olympic speeds, maybe it'll save 1/10 of a second... at diving speeds... hmm... maybe 1/100?

Anyway... if you like the way the Zeagle (Tech or BP) looks and it's priced fine, then why not?

If you're really after the Ranger (This way my 'dream' BC way back as well) ...I might have a few comments... now that I've learned a bit more about them.

First... Rangers are expensive. They usually are within the Halcyon/OMS price range already... so why not go for the real tech rigs? They aren't uncomfortable at all... and I wear a 1mm suit..no additional padding.

Second... the soft pack of the Zeagle... way back then, this was something I wasn't too fond of...it packs well for travel... but a hardpack always keeps your tank more secure.

Third... (R.I.P.)cord system... it's a neat idea... I actually give them an "A" for effort. But it's not very safe since it actually doesn't take much to tug the cord and accidentally release your weights... the handle is a T-bar that can get tangled...now if you're not going for the ripcord system... their other velcro weight thing isn't that great either... it's like Halcyon's weight thing too..which I'm not too fond of either.

Forth... oversized bladder, well, unless you really NEED 45# of lift. More lift is NOT always better... If you're properlly weighted... then you won't need a lot of lift. This being said, a small bladder actually is safer since a runaway inflator will never make you shoot up since you don't have that much lift to begin with. AFAIK, the US military uses Zeagle as well as Halcyon... soldiers do need more lift... hmm... guns...ammo... explosives... communications...etc... you get the point. And remember, none of their equipment is made for JUST DIVING. So they do NEED the lift. The nice thing about BP is that you can just change the wing to suit your diving needs. For most divers, around 30# of lift should be enough. Again, check your buoyancy... you'd be surprised at how much easier your dives get once you get it down! You move faster with less effort, use less air, lug less gear, have a lighter rig over-all, and don't have too much clutter while diving!

Fifth & last... too many pockets... although, BP are the extreme opposite and have no pockets as standard... the Ranger just has too much gunk dangling around... the weight pockets... the roll-up pocket... the Ripcord weaving throughout the thing...etc..etc..

Unless you're doing a job underwater and need a lot of equipment... one pocket should be enough... standard pockets can usually hold a slate, spare mask, finger spool, and dive tables. The roll-up pocket is the most annoying one..if you use it, the thing just dangles around like an old sock... if you don't use it... then why have it? You'd be better off with a small canvas bag and a lift bag.

I have nothing against Zeagle or any other BC for that matter... I have a few gripes about Halcyon's designs as well... this just proves that you can't please everyone.

Like I said, the beauty of a BP rig is the modularity... you can mix and match MOST brands (please check the parts first before buying though) and put together a real CUSTOM BC. :)

There's nothing special about the Halcyon AL plate I got... except it has the H logo... and I'm the type who likes matching stuff... but honestly, I could get by with any AL plate that fits the wing.

I personally like the "O" shape wing over the "U" shaped ones... for the simple reason of air-trapping. It's not really a big issue... I was just happy that the lift size I wanted came in an "O" shape. No other wing maker had an "O"... at least not here anyway...OMS's "O" wing isn't out yet.

I was gonna get the OMS IQ pack to mate with the Halcyon wing... but it cost more than the Halcyon harness... and when I finally got to try the Halcyon harness, it wasn't as bad as I thought... in fact, it wasn't bad at all... I even cancelled my order for the neoprene shoulder straps since I found that I didn't need them!

But remember, what works for me, may NOT work for you... try on as many styles as possible... borrow some rigs if you can as well. I borrowed an AL plate before buying one since the dealer was telling me to get the heavier SS plate (6# vs 2#)

Since I was able to borrow a lot of rigs before buying mine, I already knew what worked for me! I now dive with just an AL plate... no STA, no weight belt, 2# tank trim weights, and a sausage balloon stuffed in the MC storage pack. Feels like heaven to me... compared to the jacket BCs and my friend's BP rig (which had a lot of D-rings, and other stuff clipped to the straps)

Oh, another tip... don't judge comfort in the shop!!!! What's comfortable in air, may flop around underwater. Things are usually tighter in air... so just cuz something feels tight doesn't mean it'll feel that way underwater... conversely, something comfy on the shop will usually be loose underwater.

In keeping with the whole "keep it simple" idea, here's the simple answers.

The benefits of the bp/wing over any regular BC are: fit, adjustability, stability, streamlining, and buoyancy. In other words, they're easy to fit to anyone of any size, they're basically infinitely adjustable, a large metal plate strapped to your back is the most stable tank platform imaginable (has your tank ever moved on your back? it won't with a bp.), it's extremely streamlined, and they add *negative* buoyancy instead of *positive* like a Zeagle Ranger.

Yes, a 'simple' bp/wing config is best. The transpac does nothing other than remove several of the advantages of the bp/wing.

If you're diving cold water where you're going to be wearing 10 or more pounds of lead, get the stainless steel bp. Depending on the type, it will give you between 4 and 10 pounds of negative buoyancy. A "standard" Halcyon plate lets you remove 6 pounds of lead from the belt. An aluminum plate will only set you back $31.95 if you want to get one in addition to the stainless.

No, you do not need more than 40 pounds of lift with a single tank. I wear a drysuit with a 36lb Pioneer wing and could probably get by with a 27lb if I had to.

Halcyon and Oxycheq both make great single tank wings. A million people make plates and will sell you harnesses. The easiest way to do it is to buy a complete package from either Halcyon or Oxycheq.
 
I think you would find the backplate and wing to feel much more streamlined underwater. I have a BP and Wing and a Seaquest
Pro QD which is not quite a tech BC but pretty heavy duty.
I find the backplate and wing to be much less cumbersome undewater. The backplate also has the advantage of flexbility and you can use it for recreational diving as well as incresingly
more challenging dives.
As far as cost goes you can do a backplate and wing for less than a tech BC if you are willing to mix and match.
I dive the S&W metals backplate and harness and a dive rite wing. The combined package priced out under $330. I believe the majority of the Tech BC's are that much or more.
I also feel the backplate feels much more stable underwater. You have to be willing to do your research and shopping. The new Oxycheq wing looks quite nice and if you paired that up with an S&W you would still be close to the same price point.
Good luck and have fun.
 
One other comment - one friend of mine bought a zeagle bp/wing and we were somewhat dissapointed when we saw that the wing attaches using little clips around the outside of the bp instead of being bolted through the center.

Call it a reluctance to accept a new idea, but I like the center bolt connection.
