how much does an upgraded Halcyon pvr basc unit cost?
What upgrade does this PVR-BASC unit have ?
There were 2 different versions of PVR-BASC style units:
- The original unit with depth-compensated valve
- The less-expensive Halcyon-2 unit without the valve
The original retail cost of the first version was around $8000-9000, and probably was a couple of thousands less for the Halcyon-2.
However, keep in mind that Halcyon prices are always over-inflated!
About 1-2 years after it was introduced, people were dumping the first version for $5000-6000, and the second for $3000 range. Another 2 years and Halcyon were offerring to take them back as trade-in (for Rebreather-80) for $1500-2000 for the first version.
There were probably around 30-40 units made, and AFAIK, no one is diving it anymore. Halcyon stopped making it years ago, and only a handful of IANTD instructors teach the unit.
Personally, they are POS (i.e. too big, too cumbersome, not enough gas saving unless diving really deep, etc) and not worth anything
IMHO. There are units out there that I wouldn't take for free, and these fall in that category.
Just my personal opinion...
