Using this dive case is easy. Just place your Garmin inReach Mini, inReach Mini 2, or inReach Mini Marine Bundle into the case securely before your dive. Make sure the case is properly sealed to keep water out. When you're done with your dive, open the case and take out your device. Then dry the case and the device with a soft cloth. Store the case in a cool, dry place. Don't expose it to extreme temperatures or sharp objects. Regularly check the case for any signs of wear and tear. If you notice any damage, it's best to replace the case to ensure continued protection for your device.
