Can I adjust the length of EVO underwater?
The EVO has a water tight seal, but cannot be unlocked, opened or adjusted underwater. Once you unlock the collar the water tight seal will no longer be waterproof and water will enter the bottom section of EVO. The pole will no longer float for the time being once water gets inside.
If water does get into the pole, just let it air dry after use with the extension lock opened and the water will dry up. EVO will float once all the water is removed.
