Do Superstick Telescoping Push Poles Float?

Our push poles have some float-ability, but there are some factors that can effect their ability to float. Float-ability increases the more the pole is extended. Always store your Superstick Push Pole so the duck foot is somewhat facing downward. This will eliminate any water from possibly draining past the lock and between the two poles. Over an extended period of time a little water could trickle in there (if the pole is kept in a position where the foot is elevated above the lock). This certainly could adversely effect the push poles float-ability.
Our testing results:
Type of water- our push poles float better in saltwater than freshwater. They float in saltwater while fully retracted, but better the more they are extended. When fully retracted, they float right at the surface. When extended, they float above the surface. 
There is less float-ability in freshwater especially if the push poles are in the collapsed position. If dropped from a height of 4 feet above the water, they have the tendency to take up to a minute to surface just to the water line. If in a swift current, we have found them to drift up to 50 yards away before they surface. If extended, they have more float-ability and usually surface within 20 seconds. 
One customer had an experience where one flew off his boat and lost it while running through a rough harbor. We received a call from someone who found one weeks later floating a couple of miles away. We believe it was the same Superstick Push Pole. To prevent this same type incident, please review the “Installing Your Push Pole Mounting Brackets” instructions under the “Tips | Techniques” dropdown. 
Hope this helps!
