Boris is around

Mark Chase

Surley the advantage is the Boris is cheeper and dosent require you to have an engenearing degree and an electronics degree to own one . I looked at a MK15.5 and was all excited untill i found out how much it would cost to get it working and realised i didnt realy have the knowladge to do it my self

I stoped working out the cost of getting one working at arround 9k

I doubt few if anyone that has a MK15.5 is sitting on a machine that needs to be 'completely' rebuilt.

The only thing that cant easily be DIYd is the electronics - and they can be repaired by Kevin or replaced with a HH (Just like you are thinking of doing on your inspiration ) The rest is just Swagelock.

Im sure when it comes to the far more common (hundereds made) MK15 that yes, quite likely there are many out there in terrible condition (man I have seen some real dogs!) - but remember many of these are decades older and only a handfull of MK15.5s were made (20 or so I believe)

There are Inspirations out there that were made BEFORE my MK15.5 - so dont assume they are all old units that are falling to pieces

For me the open concept of the engineering means I can carry out field repairs so I have more confidence when away on an expedition that Im going to be able to repair and get it diveable myself.

The mandatory factory service intervalls may be a pita and expensive (at least for the Cis I hear), but that was one elaborate piece of equipment ... 3 setpoint controllers, dual depth sensors, dual audio alarms, four displays and five batteries ... that's a lot of bits and pieces that have to work together to keep you alive and well.

Plus some other bits like the gas management block that also needs maintainance from what I understand. The mandatory intervalls and related lockout afaik were added after production started. I remember Martin Schärr in CH selling two MK-5p and posting that his didn't have that mandatory service lockout.

The Ouroboros is a bit less elaborate, but shares some of the electronic and mechanical features of the Cis. Like pressure transducers for the digital display integration of gas contents (on the Cis two where standard and two more for additional backgas were optional). I for one have no idea what kind of adjustments those things may or may not need.

Anyway, it's a new rig, and if they want to get the units back into the factory for a thorough checkup after 200 hrs that's probably not a bad idea. It's life support equipment, remember. Nobody thinks twice about something as simple as a tank having to get viz (annually in the US) and hydro (every 5 years) or regs needing annual rebuilds.

Yes because his units had older software versions and not the latest. That was the compromise.

Kevin G. was involved in the Cis too, wasn't he ?

Fair enough about being a new design unit, and I am sure new things are being added/fixed all the time as they learn new things. But every 200 hours isn't fun to ship a heavy, large, expensive unit to UK for people living outside of UK in particular - not mentioning about the cost of shipping and maintenance.

I sold the first Explorer because I didn't want to have to ship it back to the US every few months since it was at the beginning and new software updates were popping up all the time. Plus the cases were having problem, etc. Fed-Ex/UPS the unit a few times will cost 1/2 as much as the unit...

For the tanks/regs, they could be done locally and doesn't cost anything but 1-2 days at most. And most people even do their own reg servicing.

Guys there is two ways to dive and to be honest with yourself:

- you can avoid a sensibable 200h maintenance (easy you remove the batteries for more than 1h) by then accepting to take some risk on the unit and maybe crash yourself ...

- or you get it send back to delta P and they will give it a good MOT check up and then you'll dive a bit more in peaceful mind.

Food for thought

I think I missed this - but, what is the price of the unit? 10K?

iani

Basic unit is £8k, offboard gas connectors add another £270 or so. I believe there may be 4 or 5 units available now.

Thanks for the information. (Newbie Question) I guess we can say that this is at the high end of the spectrum for RBs? I wonder if there are any US Divers using them besides John Chatterton?

jont

Have there been any issues with the unit?

Put it this way - don't buy one as your first rebreather.....
