[net.rec.scuba] Summary of Regulator Inquiry Responses

rjnoe@riccb.UUCP (Roger J. Noe) (10/15/85)

About three weeks ago I asked the readers of this newsgroup for their opinions
about the quality and relative value of regulators that are now commonly
available, especially those made by some of the larger manufacturers.  I
also asked if anyone knew of objective published evaluations.  I got a
number of responses on both topics.  It seems the only place one is likely
to find published evaluations (except those of the kind which always say,
"it's the best regulator in its price range" like in Skin Diver Magazine)
is "Undercurrent", a sort of 'underwater' (like underground) newsletter.
It's not a slick publication but then it's entirely paid for by the sub-
scriptions, since they accept no advertising.  Their address was very
recently posted to this newsgroup.  The drawback with Undercurrent is that
the writers/editors are anonymous and sometimes a little irresponsible
with their criticism.  They also apparently have not done many reviews of
regulators in recent history.  But they are a lone, independent voice.

The remarks that follow are unattributed since no one elected (bothered) to
include explicit permission to post attributed comments.  For the sake of
simplicity, I have done the same thing with opinions posted directly to this
newsgroup.  The "---" lines or my comments separate different responses.
Responses have been edited for form and relevance of comments.

I got quite a few responses which said exactly the same thing.  Indeed, after
trying several regulators made by well-known manufacturers, I found it very
difficult to tell most of them apart.  There are statistics published by some
manufacturers, but I think these differences are so fine that only breathing
machines can tell.  I may think differently doing salvage work at 100 feet in
water that's at 2 degrees Celsius, but I do not plan to do much sport diving
under those conditions.

I don't know how much can be said about a line of regulators based on a rented
one.  With the bad treatment they get, I'm just not sure any experience would
be representative of the line.

The environmental protection referred to is offered by a great number of manu-
facturers as either standard or an upgrade, intended mainly to prevent first
stage icing.  This is really only needed in cold water (a must in ice diving)
or when there's a lot of sand or silt around.

It sounds like most people have had very good experiences with the regulators
they bought.  While there are variations in cost, reliability, performance,
and maintenance I got the distinct impression that I would be satisfied with
whatever major-brand regulator I chose.  As you can see, the Tekna, U.S.
Divers, Oceanic, Dacor, Sherwood, Mares, and even Poseidon regulators all
got some enthusiastic responses and no complaints that could be said to be
indictments of an entire line or manufacturer.  What surprises me is the
total absence of Scubapro regulator owners.  I was almost sold on one of
these, too, until I decided it was just too much money for more performance
than I would reasonably need.  It's like stereo amplifiers, the total harmonic
distortion on most of these at a decent price (not K-Mart blue light specials)
is well below the level that can be detected by human beings, and you don't
buy a stereo for your cat.  (Or do you?)  I fully expected to hear something
from someone about what a breakthrough the MK-V first stage was years ago
and how their A.I.R. II makes such an excellent octopus/power inflator.

Anyway, I suppose if you've read this far, you'll probably be interested in
what I ended up getting.  It turned out that a store about a mile from
where I work which also does a heavy mail-order business, Berry Scuba, had
a sale on the Dacor Pacer 900 and Oceanic DataMax Console combination.
The package price was under $300!  I liked the regulator since it was made
by a well-established company located in the same metropolitan area (Dacor
is in Northfield, a suburb of Chicago) and the Pacer line has a good reputation
as a balanced system.  I briefly thought of substituting an XL instead of
the Pacer second stage but decided it wasn't worth the bother.  I do like the
900 first stage very much.  As far as the DataMax goes, this was exactly the
kind of thing I was looking for, so I don't have to strap eighteen things to
my wrists and arms.  There are a couple other companies which make consoles
very similar to this one, but I was especially impressed with the completely
automatic bottom timer/surface timer/repetitive dive number indicator,
mounted in the depth gauge.  Considering the price and the quality of the
package, I think I got a very good deal.

I thought another few days about an octopus and saw a sale on the Dacor Pacer
Aero second stage for $55.  Until I saw that, I was leaning to U.S. Divers
for my octopus.  If I owned a BC, I might have gone for the Scubapro AIR II.
It's going to be enough of a hassle attaching a rented BC power inflator
to my first stage every time I go diving.

Thanks to all who responded to my query.
