I got to put my hands on the pack @ Puyallup. I liked it. I understand it was just a prototype, so that's going to mean there will be some subtle changes to the production models. But, I liked how it felt on my back, and I am OK with how the bag deploys. I had some suggestions that were intended as constructive feedback, and they appeared to be taken as such. Most notably, have the deploy handle able to be set to either side. This would not be difficult to do when designing, since the shoulder straps are hollow for a drinking tube anyway. Some folks have a definite preference what side their handle is on. Personally, I could care less about a water bladder, but that's me.
Now, to the more important stuff:
I put the BCA and the Snowpulse product in the same category in this aspect: you can deploy and refill the unit.
Why this is important: I work in an emergency profession, and it influences my attitude. Anyone who does this, trains, trains and trains some more. In an emergency, you DO NOT rise to the occasion, you shrink to your level of training. (this is NOT HOLLYWOOD) Therefore, I'm not going to purchase a piece of safety equipment such as this, and just put it on and go play. If you think for a minute I'm not going to stand in my garage, on my sled, in all my gear (helmet, coat, all normal riding layers, gloves, goggles, and full pack) and pull that handle at least 15 times before I plan to trust my life to it, you're nuts. That's why firemen practice putting on their masks, why cops draw and shoot at targets, why soldiers field-strip and clean their weapons, and SCUBA divers practice regulator failures. I've never been in an avalanche, I don't ever want to be in one, and I don't ever want to have to rely on that backpack. But if I do, I want to know I can find that cord, and pull it with my eyes closed, standing on my head, and whistling dixie. I strongly suggest anyone who buys one of these does just that.
I want to thank BCA for putting the effort out to get a product to market that is at the $500 price point. THANKS!!!!!!
While I'm OK with trusting someone else to fill the little tank in there, I want to make sure the person making the connection is trained in what to look for as far as a proper seal.
If BCA wants to inspect the o-rings after every deployment as part of a on-going quality control and durability study, fine by me. I'll BUY 25 o-rings, and label each one after each deployment, and mail them back to BCA with the serial # of my pack. I'm actually 100% OK with that. I'm glad to help them bring the best product to market they can. And if it's recommended the o-rings are a one-time-use-only part, I'm OK with that too.
One of the reasons I like the BCA product, is because they focused on making the refill so easy, we as riders are less likely to 'wait' to pull to cord, "cuz it's gonna cost me $100 to recharge it"
Since the bottle is filled with dried, compressed atmospheric air, as long as it is filled to the proper pressure, and the seals are intact, it's fine. If you're going to fill it someplace else, I'd recommend a SCUBA shop for fills, as those folks are used to that process being a bit more critical than if your paintball gun won't shoot.
While all that ramble is just my opinion, I tried to share why I have that opinion, and persuade others to practice with their new piece of safety gear!
Have fun, and be safe! Come home laughing with the ones you love.
