market response to new Cis Mk6

mverick

If they can, think EXPANDABILITY. Be able to buy a basic unit and upgrade with diver plug in's. Start with a Kiss style. Have plug in pod with a O2 solenoid and computer in it. Have Plug and play larger scrubbers. Or even dual plug and play scrubbers. Plug and play Back mount counterlungs. And has to be able to travel with it easily. Be able to plug in direct a VR3, Explorer, Shearwater, F1. They do the homework so it is EASILY integratable with other units instead of making the consumer do the work. And Hard piping for everything. So, you insert your tank and screw in the din and no other soft piping for failure points.

Come out with something like this and strength and you'll be sold out.

Hello mverick, just a thought about hard plumbing, I think it's only possible on BMCL units like the MKs/Boris. Unless you forgo manual add O2 and dil add buttons on OTS CLs, you will always needs some lp hoses...

dantheman

Absolutely. This kind of thinking is waaay underrated.
All you have to do is look at the most popular (non-flamebait)
threads here: mods. Mods for this, mods for that...

Could be done but it needs thinking. Have part of the backplate extend over the shoulders and put add valves at your shoulders. Right for rich.

Think whole system. NOT, what's already been done. Pretty much every Rebreather out there is nothing more then an upgraded copy. Most still look like they were made in someone's garage. Now, maybe a well outfitted garage with a lathe and a mill. But, still a garage.

Oh, I wouldn't want any of the Additions externally accessable. One or 2 o rings to seal the unit.

You just gotta think out of the box.

The idea of hard plumbing has it's appeal, but it is definitely going to add weight and require the shell to be very rigid, no flexing. So the bp extending over the shoulders sounds heavy, uncomfortable and restrictive for an OTS CL unit. I'm sure it's possible, but I'd guess this is part of the reason why it's not been done before. And there are definitie benefits to having say the dil add on the CL, right next to your inhale hose.

Might as well get a Boris or MK and skip the OTS CL, that's what I'd do if I thought hard plumbing was a priority...

Actually, it has been done before.

Some of the Shadow Pack IIIs have been build with ss pipes rather than hoses of some sort and yet the unit is still small and light weight. It all depends on where the injection points are. Obviously injecting into front mounted CL is much less of an option, the Shadow Pack has all injection points into the head. The manual injection is triggered by levers, not unlike the the buttons on the MK, located towards the bottom of the unit on either side.

The advantage of that solution, aside from pressure proofing, is that the loop can run either way yet tanks can be on the "correct side" (unlike the PRISM) and O2 can be injected before the scrubber/dil behind the scrubber (unlike the Meg). A further plus is that hoseless CL are more streamlined.

Thanks for the info Stefan, I learn something new on here frequently, frequently from you. Do you have any pics of the unit? Does it have 4 hoses or 2?

Not sure what you mean by either way, do you mean that the piping for both side is identical?

And what are down sides of the design, what's the catch?

Ok Stefan, I found some pics at Divematics, but not sure what I was looking at, the old Shadowpack looked like BM CL-like I remembered seeing before-and the newest 1 had OTS CL, but said it was an O2?, yet had 2 cylinders? But then there was a pic of the unit with what looked like some electronics strapped to the back. Didn't see any levers for man add, and the newer unit looked like it had regular LP hoses for the gas supply...

One on each side, following the rich=right (O2) and lean=left (dil) that most everyone is accustomed to, OC or Rebreather. Piping isn't identical as in a mirror image of the opposite site, but it connects to both the automatic and manual dil on each side.

More expensive and time consuming than just cutting and crimping hoses, Schrader style add valve hard to be implement, fitting different tanks/valves may be a problem.

Don't have the page open, and don't have the time to look for it. most likely the full size dorsal mounted O2 unit. Shadow Packs can be configured as

- O2 rigs (2 O2 tanks, demand and manual add valves as shown)

- active addition SCR (needle, demand and manual add valves, also with two tanks using the same mix)

- CCR with solenoid/manual add valves for the O2 and demand/manual add valves for the diluent (picture of that ought to be in the gallery somewhere, as well as in the 2004 DEMA report on Janwillem's website)

Electronics are in the handsets, not the head. If memory serves me right one unit on the website has some sort of comm system attached to one of the straps that hold the lid ... white box I think it was.

Thanks Stefan! More stuff to digest...
