Using this ACCESS 240 avalanche probe is a breeze. When an emergency occurs, grab the pull handle and quickly pull it to extend the probe. Thanks to the cone inserts, the tube segments will fit together easily. The FLASH LOCK system will lock the probe in place with a simple knot. Once you've located the victim, snap the pull handle onto the tube so it's out of the way while you shovel. As for maintenance, after each use, make sure to clean the probe to remove any snow or debris. Store it in a dry place to prevent the aluminum tubes from rusting. Check the Kevlar tension cord regularly for any signs of wear and tear. If you notice any damage, it's best to replace the cord to keep the probe working at its best. And always remember to test the FLASH LOCK system occasionally to ensure it locks properly.
