All the stuff you relate here with the added bonus of the "most complicated interface in dive computerdom". Excuse me but I do believe that there are more important things to be keeping track of on a trimix dive than trying to figure out the most complicated interface ever strapped on a wrist. What advantage does this $1900 monstrosity offer over a bottom timer, tables and a solid understanding of deco that only comes from experience? This is pure geek stuff, hoypaloy which adds nothing to your dive but more complexity, task loading and failure points. Jim ------------------------------------------------------------------- Learn About Trimix at http://www.cisatlantic.com/trimix/ From: Ray Blanchard <rkbl@uf*.ed*> Date: Wed, 23 May 2001 19:36:09 -0400 To: Tom Mount <TOM.MOUNT@in*.at*.ne*> Cc: Alan Crew <alancrew@ya*.co*>, FLTechDiver@mikey.net Subject: Re: Trimix Computers Hi Alan, Tom & the rest of the list, Thanks for the informative posts from folks regarding trimix computers in particular the Abyss Explorer and the Phoenix VR3 as well as the limited application of the NiTek3. While not a trimix computer diver, I've been following this area closely for several years and dreaming of owning one. This past DEMA show, however, was especially interesting in regards to the VR3 which is the only trimix computer that I've seen in private individuals' hands (see Z's post regarding the Explorer). Prior to the show my information was limited to that from OMS, the U.S. distributor of the VR3, and a friend who dove one and found the user interface rather complex. While visiting the OMS booth at DEMA, I spoke at length to Kevin Gurr and another member of the VR3 development team and discovered that OMS's literature on this computer fails to do justice to the VR3's features in a big way. Since Tom with his hands-on experience didn't expound on them, here are a few of the highlights that are not on the OMS brochures: -Phoenix has a web presence ( www.vr3.co.uk ) including an electronic copy of the VR3 user manual -PC interface comes with the dive unit -user changeable standard batteries -never locks out upon deco violations -dive simulation mode allows contingency tables to be generated from the dive unit on its own -capable of complete gas control/programming even while on the dive -back lighting -adjustable conservancy/safety factor -reed switches (mentioned) mean no case penetration for buttons. Overall this unit appears to have tremendous flexibility but that also makes for the most complicated user interface that I've seen on a dive computer. Still, while I'm not a technophile, I think that I could learn to use this computer and I definitely would like to get my hands on one. The 2 biggest down sides to this unit are that OMS is marketing the OC trimix model with an MSRP of $1900 and second, as Tom mentioned, it's conservative because it's based on the ProPlanner algorithm. I know that some of my trimix diving friends down here in FL find ProPlanner to be a little too conservative for their tastes even when it's set for zero conservation (for some reason they want to get out of the water faster ;-) however, Tom's recommendation for a special order may resolve this issue. Of course the biggest point I've encountered for this trimix computer is that it's in production and available now.
