Echomax Passive Radar Reflectors comprise an symmetrical laser cut aluminium or stainless steel reflector enclosed in a robust polyethylene case. The design maximises response whilst minimising windage.

Suitable for vessels 9 to 15m. The EM230 model has been successfully tested by QinetiQ to ISO 8729-1999, and meets RORC,ORC,ISAF 2012/13 and WCC requirements of 10M2.

Echomax reflectors use a symmetrical arrangement of interacting corners. Whilst its centreband response pattern is maintained at 15° tilt RCS is -5dB. To counter this, and avoid 'mast shadow'.

Pass a bight over the yardarm via a dead eye. Return bight through reflectors eye and secure taking lines through bight. Take tails through reflectors bottom eye and then to separate cleats via loops at --xx--.


Yachtsmen will be aware of the need to trim the reflector when on the reverse tack, failure to do so will result in compounding the angle of heel rendering the reflector inefficient.

Note: Reflector trimmed to leeward 15°. Mast heeling to 30°
