Thanks for your comments and opinions. > I just bought a spare reg and some other SP odds and ends, which came with all the original paper, including several vintatge SP catalogs. Looking through them, I've come up with the theory, that at any given time, Scubapro has two concurrent lines, the "sensible" line, and the " novelty" line. For example, in 1984 you could have bought a Mk 1O/G250 (or BA) for $310. Or a sonic Mk7 and an Air1 for $540. And $47 would have bought you a K valve, or $150 would have bought you a DCAR reserve valve with a weird built-in pressure guage. The punch line, of course, is that if you'd bought the MK/10/G250/Kvalve combo you'd probably be still using them today, and they'd still be as good or better than just about anything else you could buy. The Mk7/Air1/DCAR you'd be hard pressed to give away. So when Scubapro innovates, I yawn, and head the other way, at least, until the smoke clears. How to tell the difference between legitimate innovation and novelty? Time, mainly, thought if something looks radically better than just about every other piece of gear in it's category, odds are in won't last. >Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'. >Send list subscription requests to `techdiver-request@aquanaut.com'. -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
