This fully-encapsulated unit provides the greatest return. The model 210-5 weighs under 4 pounds and is only 20" long, ideal for boats with limited space. The USCG is using them aboard their new inflatable rescue craft. Any boat can be seen by radar using the Blipper, even at 30 degrees angle of heel. Plastic coating prevents chafing of sails and rigging. The Blipper is secured to the mast with mounting brackets, or sent up the flag halyard with provided stainless eyes. The equivalent echo area is calculated at over 6 meters squared.
