Hollis PRISM II & DEMA 2007

***caveseeker7*** · 4th November 2007, 16:23

Ron, am pretty sure the unit shown at DEMA was just a Topaz with some slight modifcations, a change to the inhale plenum and DSV to change the loop direction, counterlungs and tanks reversed to match the flow, probably some Oceanic bits added as well as some color here and there. More a proof of concept and test bed than even a prototype.

Same old, same old, some people will bitch that it's not the finished final product yet.

Personally, I like the idea of the reversed flow and the tanks/gas addition being on the traditional sides, rich O2 right, lean dil left.

New DSV I can't comment on, other than that I miss the brass connectors, they were beautifully made and very much a PRISM trademark. They also balanced the DSV perfectly underwater. For a good BOV it would have been worth dropping them, for just another DSV it's a shame. Even if machining them was time consuming and expensive compared to molding.

I also believe that there will have to be new material used for the production process as I doubt that Oceanic/Hollis wants to build as low a volume as SMI has in the past. For low volume Pete's molding process works well, but IMHO the injection molding is a more likely process for future PRISM2 production. As long as those materials end up stronger than the current composite it'll be two steps forward, better build quality and shorter production times. Even with stronger materials, the cowling (hopefully not with that 70s paint scheme) needs to be stock in my opinion.

The displays, if correct, are good news. I like the analog gauge very much, but am fully aware that a digital gauge is a much more solid proposition. Personally I would like to have both and use them depending on the dive/destination. The digital also makes a perfect backup for the analog gauge.

Am curious if the actual electronics will change, I like them for their simplicity.
Counterlungs with drains, elbows instead of T-pieces, the radial scrubber,
all very good stuff I hope will remain unchanged.

I spent a fair amount of time at the Hollis booth listening to the various conversations. I heard all of the above items on loop direction, new MFG processes etc, with the exception of any discussion on a change in electronic displays. I was kind of hoping that they would have mentioned something more exciting like electronics that would intergrate with their new "HUD" mask.

Reguardless... Great show all the way around!

Mark,

How about a recap about their scooter and LED lights ?

Well, in the past at least Pete was working on what I consider an ideal setup that should work either with a wired display or Oceanic's wireless, including the mask-integrated display.

He wanted to add realtime deco (RGBM) by transmitting the pO2 data from the cells via IR from the head into an optional battery cap that would contain the additional electronics/power supply for the deco computer and display.

That would keep the setpoint controller and the deco computer completely separate from one another. Aside from changes to transmit the data, the current electronics could stay as they are, yet deco could be computed with actual data from the loop.

Shouldn't be a problem to do it wireless and utilize the data mask.
Would be a very nice setup.

Though I still like the idea of a FFM better ...

Im pretty sure the scooter was a relabeled X scooter, looks like oceanic is going the way of OMS, as in Other Manufacturers Stuff. But I still like the datamask, wish they would make it compatable for PO2

While I'm convinced that the image on the Hollis website front page is indeed a "photoshopped" X scooter, the scooter that Hollis had on display at DEMA is not an X Scooter, or Re badged X scooter.

The X uses a brushless DC motor and in a slightly smaller package offers similar thrust and burntimes at ~36 lbs ready to dive.

The Hollis scooter continues to use the Oceanic / Mako brushtype motor, and is spec'd at 60 lbs.......

It is not an X scooter as official announcement was already made from X people.

Looks like Hollis merged the ideas from the X and Suex together to make their own version.

I was hoping that someone actually looked under the hood could comment about the manufacturing quality, etc.

I looked........... the build quality looked good, neat and clean. But the ergonomics were off. The handle seems small and thin, a long dive on that will be a pain. The version at DEMA had a 3LED light in the nose. Too wide of a beam in my opinion and will produces more scatter than comfortable in particle laden waters.

Missed the boat on that one too

Thanks... looks like the Suex hull retention idea.

Any chance that you took some photos of the handle and back end ?
