It always makes sense to test the products before an emergency occurs. And the Airbag 3.0 Trigger Test Tool is ideal for testing the avalanche airbag before use. Because in a dangerous situation, the airbag system must be fast and reliable. With the Test Tool you can trigger the airbag without having to use a cartridge. So you can train for releasing before the next ski tour and get familiar with the situation. Simply screw the tool into the release mechanism as far as it will go, put on the backpack and pull the release handle. The successful triggering is confirmed by a distinct clicking sound.
