Thanks Mike! I hope to get a lot of posts with ideas like yours for this section. It gets really frustrating reading the reports showing the high volume of visits the forum gets daily but participating and contributing seem to be up to only a few of us......BigMike wrote:I spent a lot of time in the pool when I first started diving with a double hose reg. Being comfortable with the way that it breaths when in different positions is much, much easier in a pool environment than anywhere else. You just can't throw it on a tank and dive at your favorite spot like any other reg. That's my 25 cents (adjusted for inflation) . Mike

- Ok, I get the rig is position dependent, but how "bad" is it? I often dive slightly tilted upwards and every now and then must go into an unusual position to get the camera to a better angle. Is it possible to do that with a DH or does being "heads down" make breathing too difficult to be sustainable? Can I swim/stop/shoot sideways? If I roll over my back (to shoot the boat from bellow, for instance), does the regulator have a tendency to freeflow or will it freeflow for sure?

- How "self-serviceable" is a Kraken unit, considering I'm thousands of miles away from the experts and have never seen a double hose? Doesn't seem impossible to do, I just don't want to need a phd in engineering.
The Argonaut regulator is based on sound, reliable and proven design principals. Anyone with experience servicing diaphragm first stages, especially Conshelf based first stages should have no problems servicing an Argonaut. There is no set time between service intervals due to the inherent reliability of it's design. My personal Argonaut was last assembled almost two years ago on a patio table in Cozumel. I have used it myself on dozens of dives and loaned it out to several other divers who used it in fresh and salt water with nothing other than rinsing done to it. The high pressure seat is actually closer to 4 years old and still holds a constant IP pressure. I am taking it back to Cozumel in November and have no plans to do anything at all to it before the trip.
- Is it nitrox compatible out of the box?

- How does it fare in cold water?
To add to Hermans Info......Double hose regulators by design have always been renowned for their use under the ice and in cold water because the majority of the first and second stages are isolated from the water. Here is some more first hand info from Jim.

- How do you keep it clean after diving? I understand some water will enter the mouthpiece and be exhaled through the left hose, so how do you remove the salt after the dive? Is it any "harder" than a modern single hose reg?

- How do you handle surface swims? Is a plug necessary to swim over your back at the surface?

- How tough are the hoses? Do they handle crowded boat dives well?
Boat crews have a difficult job and are always pressed for time. mis handeling any piece of equipment makes it more prone to breaking or failure. The Argonaut Kraken and hundreds if not thousands of other double hose regulators go boat diving every year with no problems. Can it happen, of course but with normal care the chance of damaging hoses is minimal.
- How do you remove it from the water if your BCD doesn't have a handle (and of course the boat doesn't have stairs)? More often than not I've seen boat crew just grabbing the first stage/tank valve and pulling it up to the boat, which doesn't sound like a very good idea with a DH reg.
Herman got it right
- And last but not least: I get the backplate is better to keep the can close to you. With that being said, is it still usable on a jacket BCD? How noticeable would be the performance loss?
You have purchased the best setup for diving any double hose regulator that we have currently and my advice would be to stick with it and leave the jacket bcd to the students and rental fleet.
