BCDs Vs. Current

[Nick_W]

I've had so many people tell me that X doesn't affect drag and Y doesn't affect drag just because as humans we are not hydrodynamic as it is.

Gonna throw int the BS flag on this one.

The difference between a drysuit and wetsuit drag is EASILY felt

The difference between 8" tanks and 7" tanks can be felt (doubles)

The difference between your stage bottle hanging down a couple inches and up tight is majorly felt.

True 'nough we are not very slick creatures in the water, but we are not talking about wind drag, drag in the water is much much higher so every bit counts.

If you don't beleive me try it, especially swimming into hard current.

I've seen people dive single tanks on the zeagle tech, they loaded up with INSANE lead to keep the wing from tacoing around the tank AND made their own bondage wings by putting surgical tubing around the bladder in spots.

Wrong tool for the job in my opinion.

You can throw a BS flag all you want. If I can ever find the dang thing I'll throw scientific research right back at you. If you start dangling large items way down away from the body yes, you'll start to feel a difference not only due to drag, but also because stuff down away from your body moves around more than stuff you keep in tight.

Sorry, I'm blowing the BS whistle on you being able to feel the difference between 7" and 8" tanks. You may feel a difference, but it isn't due to drag.

Clearly there is a difference between a wetsuit and a drysuit. Would you like to compare any more apples with my oranges? We weren't talking about wetsuits and drysuits.

Like I said, if I can ever dig the thing up again I'll post it here (and save the dang location ) and you'll see that when it comes to the wings, the effects of drag are so minimal that I would never even dream of using that as a reason to tell someone not to use a certain wing. Not when there are plenty of other perfectly good reasons not to use it.

Throw all the science you want at it but when I look at how far I get in a cave compared to my SPG and feel how much harder I'm working, thats all the facts I need.

OK.... lets set this mis information about Zeagles Tech and Tech Pac correct.

To start I have dove dang near every kind of bc design from jacket to bp/w to hybrid back inflate to early 1970's steel plate and canvas webbing....so my comments are based on experience.

I am guessing that many of the respondents here on this thread have in fact never dove the either product, let alone even seen one....some folks just don't like Zeagle just as some hate Halcyon or Dive Rite....many 'hear' or read from scuba forums incorrect information....the same goes for just flat ruling out 'all' larger lift wings.

Actually both gear platforms are well designed and manufactured for serious diving....be it sport or technical. *I persl. dive Zeagles Tech Pac which is a full on technical bc....no way around it.....I have many dives on it as well as a Tech in all sorts of dive situations, neither have ever failed to preform at the given task and dive, nor does this special designed wing create excessive drag in the water.

Do these 2 products fit the need of a recreational singles Al80 diver....probably not in terms of the best solution for that type of diving. ....can it be dove with an Al80-yes. The systems are set up for 'large' single configurations (in my case a large HP130) or doubles (in my case steel). I mainly dive my Tech Pac with steel doubles and many times in accompany of multiple deco/stage bottles and other gear.

The units 65lbs. wing is designed with what in essence is a wing strap....hmmmm, the wing has an adjustable strap which is to be used to pull the wing down to help correct any 'tacoing' of the wing when the bc is dove in a singles configuration....it does work very well. It serves little purpose will diving doubles as the taco effect is not at issue.

I have only dove this Tech//Tech Pac with an Al80 on 2 occasions.....again its diveble but is not really the idea behind diving this system. Does a 65lbs. wing trap gas.....it can as do most other wings regardless of size (thats one reason for dumps).....this particular wing has 2 dump valves in addition to the inflator dump.

In terms of having to carry massive amounts of wt. that is just another wise tail......the Tech Pac dives and preforms just the same as any quality bp/w configuration....it is streamlined....but all dive gear creates drag of some sort.

There are many types of bc's,,,bp/w configurations on the market....select what going to be best for your diving conditions and indv. needs...be open to change and modification. For the record, I like bp/w's and other manufactures bc rigs....I am not on Zeagles payroll..lol...I just believe in the product and its designed performance.

The Zeagle Tech and Tech Pac are not going to be the gear for everyone, nor do every diver require such platform....but if you do they are fantastic choices.

I offer an open invatation for anyone to dive with me ....or give my Zeagle Tech Pac a try.

Just my .05 worth of input.

Happy and safe diving!!
