The Davis EchoMaster are made of stamped aluminum sheets with locking corner rivets. Echomaster radar reflectors return the same signal as reflectors costing hundreds of dollars more. 12-1/2" diameter heavy gauge marine grade aluminum plates provide 13.2 yd² of reflective surface. Tough injection-molded, captive corner latches assure minimum angle error and provide optional mounting points.
