Now the cylinder is ready to be filled, using the same procedure as the Snowpulse 1.0 system. Once filled, screw the cylinder back onto the backpack’s puncture unit, secure it to the pack with the velcro strap, and zip up the cover. You are now ready for your backcountry skiing or ski mountaineering.
As an extra benefit, the new system is compatible with ABS cartridges. Though this is officially not recommended, I’ve tried this and it works fine. Thus, when the new and significantly weight saving ABS carbon fiber cartridge is approved by the US Department of Transportation (yes, still waiting, though it’s available in Europe) you’ll be able to use it with your Snowpulse (who are also working on a carbon cylinder but are a year behind). Another bonus is the added flexibility if you are unable to refill your Snowpulse cylinder but are able to obtain an ABS cartridge, which are about 40 grams lighter.
