Up here, of the Sherwood regulators, the Blizzard is
prefered for cold water. Personally, I use US Divers ARCTIC.
However, try yours out in a 30 foot test dive. If it
free-flows, then it is no good.
Be warned, though, that your use of it can affect
its probability of free-flow.
If the air temp is below 32F (0C), then do not breath
through the reg unti lit is under water; then keep it
under water.
This means, when doing a scissors entry, entering without
the reg in your mouth !
Also, you descend before putting the reg in your mouth.
Slightly different to your training, perhaps, but these
techniques really do help to avoid free-flow.

I have been diving with the Sherwood classic for about eight years
and bout 200 dives. I have never had a malfunction. the spectrum
of my dives has been small inland michigan lakes, the great lakes,
the caymans, cozumel,bonaire. I have done about eight ice dives
with it including the certification for the specialty by PADI.
I have it serviced annually at the local dive shop. I have used other
regulators and I always come back to my Classic. I've never
had a free-flow with it in any conditions. I think so much of this
regulator, that when my wife decided to become certified, I bought
the Classic for her. It is a fairly easy regulator to service also. I
hope that this helps as far as another opinion goes.

Never use a reg that is designed to freeflow from the first stage 0-)

Come on now,
The Sherwood Dry Air Bleed system is a proven design that works and is
patented. It is used in cold water situations as well as warm.
When serviced properly, the positive purge system uses less than two breaths
per dive.
Good diving!

Then tell me why, when I was using brut on a pony that was not used, It
loses 100 psi an hour. 100psi /hr is more than 2 breaths. I've heard the
line of BS before.

I have left a Sherwood Blizzard on an alum 80 for 2 days. Lets see, 100
psi/min for 48 hours; thats 4800 psi in a 80 alum. I don't think so. Maybe
its time to service that reg.
Steve McGough
My guess is that the regulator is not serviced properly.
Hooked up my complete Oasis system last night with pressure gauge and Shadow
Plus.
12.5 Hours represented a change in tank pressure from 2600psi to 2250psi - a
loss of 350psi in about 12.5 hours.
It was hooked up to a 13 cf. pony bottle last night.
As for the about 20cc's per minute, I'd have to do some figuring on if that
was the case during the 12.5 hours.
Good diving!

Huh? Not quite sure to what you're referring here.....
Is it a tongue-in-cheek refernce to the Dry Air Bleed System or and actual
reference to Sherwood's SCUBA design philosophy?
I didn't see any <<< ;-) >>> that's all.....

I'm not sure what the metric translation is, but in English measure, your
Sherwood is bleeding about 16 cubic INCHES per hour. That's the equivalent of
one breath of air lost every 4 hours.
I did the same experiment. My Sherwood bleeds a little faster. I'm loosing one
breath of air every 50 minutes.
Considering the absolute 100% reliable performance I've gotten from Sherwood
regulators over the past 14 years, I think I can put up "shorter" dive times
caused by the loss of one breath of air from the cylinder.

Just out of curiosity, did either of the experimenters
above (lost one attribution, sorry) measure temperature
differences during their 12.5 or 1 hour tests?

Good question Mike,
I guess that since it was in my dining room for the entire time, the
temperature on the floor where it was located experienced about a 7 degree F
change in tem from 70 to 63 back up to a high of 70 in the am.
The tank was in that same temp range for almost 8 hours before I started the
test.
Good diving!

We have the Oasis IIs and Shadow +s and lose aroud 15cc/hr at the
surface. Temperature is a good point but the more important item is
depth. As you know, at 10m we would lose 2x as much, at 20m 3x, etc. I
would not trade our Sherwood first stages they are solid as a brick!

I still think it is higher rate of loss than being admitted to here on this
NG. The one factor that isn't in the equation is the air used just to
charge the reg from the pony bottle. If you give a little so will I. I
will leave the patented freeflow alone.
At the beginning of this post was someone that wanted to use this reg for
cold water diving. That I won't leave alone. You shouldn't use this brand
of reg for anything but pool or warm water diving. They belong in water
+50*F. In all my diving the only 2 regs that I haven't seen freeflow is my
18 yr. old usd conshelf and an Odin.
You can put a Dacor reg in warm water and you may survive the dive. This is
cold water we are talking about. There is no exceptions to the rules of
using regs. This is your life support. Buy the best that will perform in
cold water and you will know that it will work all the time in warm water.
I'm flame retardant... Give me your best!

Yes, 73 degrees at begining and end of test.

Don't flame it if you havn't tried it. You can add the Sherwood Blizzard to
your list. I've used it under the ice many times. Occasionaly with very heavy
breathing from workload. I've had to knock chunks of ice of the regulator's
exterior in order to change cylinders, but it has never free-flowed. Of course
that could also be attributed to the fact that I keep my Blizzard serviced
regularly, too.
