Lalizas 72076 Radar Reflector, Tube Type Lightweight and compact design offers almost no wind resistance and will not interfere with sails. Eyes on both sides allow the unit to be secured snuggly to the shroud. Radar reflectors are useful to enhance your boat’s signal on the area’s radars. They reflect energy from the radars and thus enhance the signal of the vessel. This is very useful, not only on emergency cases but also on situations when visibility is low and other nearby vessels cannot see you.
