Still seeing ZERO reason I would want to have a battery in my pack, and a setup that deploys much more slowly... all while supporting the people destroying our ability to do the sport which is why we have the bag in the first place.
Some good points, backcountryislife, that folks can consider when making a decision.
Like many have pointed out, my biggest issue with these bags is the stance the manufacturer takes on motorsports. When one looks down the list of anti-motorsports companies, there are so many brands on the list, one can almost not own anything outdoors/backcountry related unless it is specifically from a motorsports company (and they don't seem to make very many tents, skis, hikingpants, etc. Ha.) Definitely a varying degree of anti-motorsports funding and support among them as well; some are worse than others. But that support is definitely something a person should weigh when making a purchase.
Regarding these packs deploying more slowly, that is just not the case. So folks don't get misinformation, please note that the jetforce deploys the same speed or faster than canister packs (and, as mentioned, has one additional pro which is the ability to continue pushing air if needed, such as with a tear, that a canister does not).
fill times:
jetforce - about 2 seconds
BCA - about 2 seconds
ABS - about 3 (and sometimes 4) seconds
If anyone is interested, a quick look at the many available deployment videos online will give a good representation of deployment speeds and also good "walk throughs" on each pack type.
Some people don't like or trust batteries, which is fine. I've always seemed to have good luck with them provided one is treating them right and replacing them at prudent times and, for me, don't see these using a battery as being a con. The pro is you don't pay for a canister refill upon practice deployment; which is a pro shared by the air systems if you have a refill setup like Backcountryislife. Yes, battery replacement down the road is a cost, as is the air refill station or going to a scuba shop or firestation for refills, or paying for nitrogen refills/hazmat fees. All have expenses, including the initial cost of the pack. So much to be calculated if one is interested.
Tons of good info in this thread from everyone. Nice to have many heads thinking through the pros and cons of the various systems so folks can sift through it, helping them compare and contrast on what's right for them.
As has been discussed, the most important aspect is training. Intro classes are free, so start there. But spend the money on an "in the field course" before you spend money on any avy pack. The hands on education of those courses is great and will potentially help you make better calls each day you are out and that might keep you from having to deploy your bag as a last resort.
