This is the same pump as our other pump with the added value of having a paddle support and a compass added . With the paddle support added to the pump it allows for the pump tethers to become built in paddle leashes as well as other benefits. This is not just a water pump it has two built in leashes to help keep your pump tethered to your kayak. It also has a tethered spout plug to keep out the debris that could enter to foul the pump. Spiders and other bugs love to hide in ordinary pumps and may surprise you while under way. This pump will eliminate those fouls and surprises. It is also designed to float with the plug in or out of the spout with the aide of it's space age floating HDPE plastic components and marine grade inner foam inserts. By design it will slowly lower it's profile in the water to keep the wind and waves from pushing it away from you should it become loose from you. It will never sink. High visibility yellow will help it be seen. Truly a PADDLE LOGICAL design.
