Tibby,

Couple comments...

- Your purchase of a Meg with APECS 2.5 if definately not a bad one but there was a lot of great stuff at DEMA that will be further reported on as the RBW Staff gets back on the ground.

- The Sentinel is an quite a piece of engineering. The CL's are completely protected in the case. Kevin has taken his experiance from the Boris and has really taken it to the next level with things like automatic calibration etc.. (The head senses when the scrubber has been removed and will automatically calibrate the unit based on air.) There are also various options for scrubbers and OTS Counter Lungs... The only two things that I was not excited about with the rig was the BOV (Size) and the "Thickness" of the rig. This is due to the large diameter of the scrubber.

- The CIS is also a very interesting rig. From a technical perspective they have a very inovative approach to cell calibration and redundancy. There is a nice white paper on their website outlining the approach. Their overall focus is on "simplicity" and along with it they bring some rather inovative ideas. I agree that the unit is not as robust as some it may need to be but I would expect that will evolve.

- KJ and GG have done a very nice job with the new HH CCR. There are scrubber options other than the 7.8 lbs version. Both larger and smaller. The configuration is very flexible when it comes to 02 injection allowing for anything from MCCR to full CCR or a combination. It's also nice seeing the focus on providing a BMCL option to those that want something other than an OTS option. As far as the electronics go, as previously posted, deco is avalible on both the primary and secondary today. I would expect that anyone considering the Meg will also give this unit a very hard look.

- On the C02 front, I agree with you. I was hoping to see more movement here since last year.

While I did spend two days on the show floor I am definately looking forward to all of the interviews that Stuart and the team will be posting shortly.

Dive Safe...

Hi Mark,
Thanks for your reply and clarifications. It appears I am speaking too soon about the new stuff (not enough info). I'll keep reading. The GG BMCL is definitely interesting. I do wonder though if it's worth the trade off form the convenience and WOB of OTS to the clutter-free comfort and streamline of BMCL. Either way, I'm not ready to try that yet, gotta' dive some more to find out.
Cheers,
Tibby
