Visibility in Open Water. The brightly-colored Swim Buoy is a swimming safety float that exceptionally visible to boaters, jet skis, paddlers, and surfers. Improve your visibility to avoid getting decapitated by a jet ski or a speed boat. Swimmers in black wetsuits are virtually invisible in the open water - Swim Buoy will display your prominently in the murky waters of the Loch Ness Lake - even the Loch Ness Monster will not confuse you for a tasty harbor seal.Safe Place to Float and Rest. Because of the natural buoyancy, swimming safety float can be used as a flotation device. You have reassurance that in case you cramp up or simply need rest, you are able to grab the float.Very light to bring with you on a paddleboard or kayak trip. While the Swim Buoy does not replace personal floatation device (PFD) or a swim life vest, widely used by kayakers and standup paddle boarders (SUP& 39;s), the Swim Buoy is very lightweight (only 10 oz) to bring along for a refreshing swim workout in the open water. Add a bike blinker inside the float and your aqua-visibility quadruples or maybe even quintuples.Improved Monitoring of Athletes. If you want to keep an eye on your swim buddies or make sure that other swimmers are still in the race, spectators, officials, and lifeguards alike will appreciate the ability to see the swimmers from afar with the swimming safety float. If you put your cell phone in a waterproof phone pouch, you can have your phone sharing your GPS location too to track exactly how far you swam AND to broadcast your location in the water.",
