>>>>> individuals'
>>>>>>> hands (see Z's post regarding the Explorer).  Prior to the show my

>>>>> VR3,
>>>>>>> and a friend who dove one and found the user interface rather

>>>>>>> another member of the VR3 development team and discovered that OMS's
>>>>>>> literature on this computer fails to do justice to the VR3's

>>> 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

>>>>>>> conservative for their tastes even when it's set for zero
> conservation
>>>>> (for
