In a dangerous situation, the avalanche airbag must be triggered quickly and reliably. The Airbag 3.0 Trigger Test Tool allows you to trigger your airbag without having to use a cartridge. You can use the tool to familiarize yourself with the airbag system and practice deploying it. Simply screw the tool into the release mechanism as far as it will go, put on the backpack and pull the release handle. A clear “clack” noise confirms successful activation.
