Colkan Eagle

Anyone have a web site or email for these folks?

Colin is at: cw@colkan.com

No website as far as I know. He's strictly been a word of mouth advertiser. His major work is with industrial users.

His Mark-16's (15.5's), BTW, are state of the art and are priced accordingly. They stand now as the most expensive rebreather available to the civilian. Worth every penny.

Hi Dave,

If you had to choose between a Sport KISS and a Colkan Eagle, which would you choose and would it be a tough choice? Reason I ask is that I just heard the price of the Eagle versus the SK, and have become very interested in getting one, especially since it will be available relatively locally.

Hey isn't the rEvoII in this price performance area also?

Hi Fireman,

From what I've read on DiveOz following the recent OzTek convention, the rEvoII is around the AU$9000 range just like the Pelagian, while the Eagle is around AU$7000 much like the SK.

Cheers.

IMHO, these 4 should be in the same price range.

You'd be giving up your preference for OTS lungs by purchasing either, mate. You sure that Andy Fritz at rebreatherlab couldn't make you a custom Pelagian with a manual add instead of an ADV?

Marek, While I am not Dave I will have a crack at this

having an SK in the house I'm definitely looking to get a Eagle assuming the depth rating is what I am looking for (min 80m). For wreck diving it's profile is better than the SK and the unit is more abuse friendly when bumping through wrecks. Rachel lost her O2 recently in a wreck when going through a passage way (damage to HP line) as the SK is pretty wide and the chance of pod damage is also always present.


One of the nice things is that the O2 gas side on the ECCR runs at 16 bar, the MCCR version was to be set at about 9 bar to give 80m depth range, but theoretically you could reset the valve to 16 bar and have a MCCR O2 delivery with 150 m depth capability, since the control is just a set and forget needle valve.

Also been working over the reliability given the point Dave mentioned on the use of upstream valves for certain functions and I think this unit will be rock solid from a reliability point of view, plus the quality of the construction. One thing I quizzed Kane about was the stiffness of the chassis as that is what will drive the life of the hard fittings and he indicated the chassis was pretty stiff with no flexing so the hard piping should be very reliable. This unit is incredibly neat and tidy inside.

Hoping the can get it to market shortly. They have been working on this project since 2003, so like all rebreathers is taken a long time to get to market

Direct from the horses mouth Colin Said, "digital electronics are "flakey" at best, we will be replacing the digital system with an analog one" This was quoted from Colin, I was in the room during the seminar, I am not commenting on things I have not seen. also they had not provided a place for a 4th cell, but alluded they may be doing that. Are you or are you not? simple question.

If the software hangs (assuming its digital and they dont go to analog) the LED can burn green all day and the CCR could be not delivering gas, this is a "bad" alarm, you only know that it works WHEN it works, not the rest of the time. If its analog, the transister can fry and stick a solid green out there too. A flashing type HUD that is delivering information on each loop of the software subroutine is much more effective as an alarm as it also informs you continously that the software is still running. the smithers type coding does this, as well as actually reading all three cells value. Just cause its what you grew up with, doesnt mean it the best, sorry dave

again, according to Colin, the backlight sucks juice and will significantly deplete the battery, I asked why it was set up so that you couldnt turn the BL on during the dive, he retorted with "dont you carry a dive torch?" Sorry that was a salesman talking around the poor design features and you, dave, are defending a poor design. Question, if this was something alien to you and not your best remembered design from the warm fuzzy past, would you be defending it quite so much? There should be a way to turn the BL on During a dive, not have to decide it Prior to the dive, that is just plain lazy design and stupid. How about a tap sensor? Colin said they didnt want any switches to pierce the hull of the PO2 meter, but then they put this silly hole in the back for calibration that REQUIRES the diver to break the seal into a unit that is NOT potted (I asked) every dive that either needs calibration, or you decide to change the state of the Backlight.

Not a bad thing for the diluent side

this is however a bad thing for the oxygen side, with 200 bar on the manual inject valve, how much oxygen do you think is going to flow into the rig when one hits the button at depth....hmmm, Im dont have the flow rates or hose diameters, but Im going to hazzard a guess and say more than I would like, a lot more.



Not sure if we are talking about the same thing here, this is not the old analog millivolt scale with the thumbwheel. Pic added. Couldnt get it to light up, cause it required a .4 PO2 to come alive, great for testing the unit right before a trip when you might not have any O2 to run the loop up. (sarcasm added) So it may be a great secondary, Right up until it floods cause someone was in a hurry and didnt screw the plug in correctly. How hard would it be to add one peizo switch (draeger oxygauge) a tap sensor (rEvodream) so one could activate controls w/o breaking the seal?

I have pointed out quite a few problems with this unit, I was the red headed stepchild in the crowd, Colin was not happy with the questions I asked and tried very hard to brush them off, rather than explain with logic and design principles, he weaved and dodged like Bill Clinton at an inquiry. I wasnt tryin to shoot this down, honest, but I tend to ask questions and when I dont get good answers, I tend to start digging deeper.
