Differences between 'Boris and Sentinel?

Marvintpa · 29th October 2007, 14:03

Not sure information has been out long enough to get a good answer on this, but does anyone have a good idea what the differences are between the 'Boris and Sentinel and how those affect actual diving? (tough when virtually no one has dived a Sentinel, so I'll apologize for that in advance).

Differences I'm aware of:
-Boris two counter lungs, Sentinel one (what's the effective difference?)
-Boris radial scrubber, Sentinel axial (what's the effective difference?)

Does the Sentinel have the ability to take other sizes of tanks? Or do they go inside the cowling like an Inspiration? All the pics I've seen so far are cowling-less.

What material is the Sentinel cowling made of? I'm gonna guess it's not carbon fibre.

Thanks in advance.

In few words (Note I never dove a single CL CCR):
Ouroboros more performance at depth because of the scrubber.
Single CL = more WOB but it is compensated with cannister size, etc.
Single CL = less loss of heat, less points of failure, ...

As option there is a OTS CL without shell, easy to travel with and I suppose multi size tanks then.
More infos soon.

Differences I'm aware of:
-Boris two counter lungs, Sentinel one (what's the effective difference?)
Less dwell time with one CL
-Boris radial scrubber, Sentinel axial (what's the effective difference?)
Radial believed to be more efficiant

What material is the Sentinel cowling made of? I'm gonna guess it's not carbon fibre. Correct guess but neither is the Boris

Thanks in advance.

What IS the Boris cowling made of?

Glassfibre, I think with a carbon-fibre look covering

The back cover is Carbon Kevlar according to ccrb last time I checked.

We have 2 Boris' and both back covers certainly look like being made of carbon weave to me. What makes you think it's glassfibre?

Sorry, I was wrong

...well, I did say "think".,., but I know what "thought" did eh?

I "think" it's the first recreational Rebreather to come with a BOV as standard. If I got that right, then Kevin Gurr is to be highly applauded - that simple action, IMVHO, will save lives.

Hmm, how about Kiss and Pelagian then?

I thought for both of those the BOV was an option?

Happy to be put right...
