I purchased a Zeagle Escape and am using the Zeagle 24lb wing. I normally dive a Ranger but wanted something lighter with less lift and much less packing bulk - headed to Bonaire on the 27th. Problem - just got the BC set up, tried in pool with camera. When I adopt a head down vertical attitude, the knob on the end of the string that activates the pull dump on the bottom of the wing drops behind the bungee cord that serves as a retractor for the wing. Happened twice and I can replicate it on shore. When I complete the rotation and go head up, the knob sometimes completes a loop around the bungee cord. When I inflate the wing, the obvious happens, the bungee tightens, the loop tightens and jams against the knob, which prevents the loop from self-unwinding. and the string partially opens the dump valve, preventing, at some point, additional inflation of the wing. I can't fix it with the BC on - tend to make it worse. Not good. The bungee arrangement on both the 24lb and 35lb wings passes across the top of the dump housing.

Any ideas? Four have occurred to me. The obvious - take the Ranger - no bungee, long strings on the pull dump, smooth wing housing for the bladder. Biggest downside - more lift than I need, small bubble rolling around in big bag.

The draconian - cut the string back to the housing, forget about the dump.

The more subtle - open the dump housing, remove the string and knob, replace with a much longer string with no knob on it. Can I do this easily? Dealers don't like to endorse end-user mods like this.

Or cut the knob and tie another length of string on making the cord longer but still having a bump that could snag, not to mention come loose. Not a good idea, I fear.

This probably has something to do with the way I move through a rotation that is unique to me as I've never seen a post on this issue; however, I recall reading on the DIR page that they require that the pull dumps on their gear have no knobs that can snag. They also won't use bungeed wings but the bungees are covered pretty well with the wing body on the Zeagle design and shouldn't snag easily - I don't do any penetrations - , not wrapped around the whole thing as some vendors do.

I'd hate to toss the Escape as a travel BC, too late to learn another system now anyway for Bonaire trip. I find the Zeagles very comfortable and customizable to fit my over 50 shape.

The Ranger's 44lb wing doesn't use bungees and has longer strings. Actually, if option three above is viable from an end-user standpoint, I'll probably modify the Ranger this way, too, so nothing can snag.

Any thoughts or suggestions? To me, a longer pull cord, maybe thicker, with no knob is the way to go if I can safely make the mod myself - no time to send things off.

There are several options that you can consider. The first and best in my opinion would be to get rid of the bungeed wing and switch to a non-bungied wing. 2 reasons= 1. can you manually inflate your 24# lift wing fully? 2. that would immediately eliminate the problem and it couldn't remain a problem

regardless of what you are going to do, I would cut the ball off as this is sure to help. Know the location of your dump and be able to touch the dump, not look for the ball.

hope this helps
 
Thanks for the notes. The bungee doesn't completely encirlce the wing but appears to serve a retraction/streamling function. I'm going to try removing it today and see what happens in the pool - If it flaps badly, I'll be back to using the Ranger, I think, with it's smooth wing.
 
Yeah, I agree with Divesherpa, get rid of the bungied wing. They are nothing more than a gimmick that create a lot of problems. I know a guy that took the bungies off his Dive Rite Rec wing, so that may be an option too for you. I'm not familiar with that wing, so I don't know if that will work for you.

Good luck.

Tried several things at noon in the university pool. Removing the bungees works fine, don't look like Rodan flapping through the pool at all. Also, putting a knot higher in the cord past the knob to keep it clear of the cords - that works, too - it can't flip around the bungee, if I were using the elastic cord at this point. Thanks to everyone who had a suggestion.

The 24lb wing is just the trick with a .5mm suit - in the pool I only needed about a 1lb of lead (if that much) to sink on exhaling with a full tank. The camera rig will take care of that. Obviously more will be needed in salt water (I use 3% of all geared up weight as a starting point then remove weight if I'm okay at 700lbs or so at 15-20 feet for the safety stop). Also, the small wing had no tendency to "face plant" when filled at the surface yet kept me clear of the water to below my mouth. One other thing I've found - if the water's warm, I jump in with the wetsuit on but not zipped, no gear, then zip it up and put the gear on. I guess if I put it on and zip it tight over dry skin, air must be trapped somewhere, probably the small of my back as I tend to be a bit swayed.

The Escape design pulls the weight pocket/gear pocket assembly further towards the diver's front - it's easy to remove and replace the famous yellow weight pouches for in water adjustment. The outer pockets are really small but can easily be opened in the water. As with the add-on rear weight pouches on the Ranger, the built in trim weight pockets on the Escape can easily be accessed for weight dumping or replacement in the water - longish arms help.

The Escape shares the PFS sizing system with other Zeagle BC's. There are adequate attachment points for a camera/strobe/tray. I like to clip off both ends of the tray so the Motormarine IIEX system doesn't dangle.

The BC folds up into a rectangle about the size of a ream of typing paper and seems to be a solution to the carryon problem - I can get the BC, a reg and mask, a bathing suit and some clothes, film, and the .5mm suit in a slightly smaller than max legal size carryon bag. For the record, the Ranger will also fit, but with room left only for a mask. The material on the BC is light - 420 versus 1050 denier fabric. Swimming seems quite a bit easier with the Escape than the Ranger but I have no way of scientifically confirming this. If one wants to, the Zeagle accessory full lumbar pad fits the Escape as well the Ranger - I use it with the Ranger in quarry dives around home as I generally wear a 7mm suit with commensurately more lead because of the thermocline temp drops.

The Escape, from pool dives only - Bonaire will be it's first open water use, does not appear to hold the tank as rigidly as the Ranger. The stock upper band on the Escape is a light webbed quick release strap. The soft back of the Escape is about half the thickness of the webbing on the Ranger and can be folded quite easily. A camband could be used but I have to keep remembering I bought this BC for light weight and easy packing. The tank mounting difference does not appear to produce a problem, based on rolling and flipping in the pool. The tank doesn't shift or slip after a giant stride entry. The strap/waist geometry, as with the Ranger, seems to effectively shift weight from my shoulders to my waist.

All in all, a good solution in these days of reduced carry on luggage.

Best wishes for a safe holiday season to all.

This is the first (EVER!) complaint that I have ever heard on a Zeagle BC. I am certain they will want to address your problem.

Is to get rid of the ball on the dump valve and just use a knot at the end of the cord. None of Halcyon's BCs have balls on the dump valve. They are not included with the BC for that very reason.

I had a similar problem with my ScuabPro RecTec.

I just rethreaded the bungy to not use the last loop on that side and the problem went away. I want to keep the Ball thingy because it is easier to grab with 5mm gloves on (I can feel it!)

My $0.02 (Canadian).
