Takex 11m Reflector Active Beam External

This is very high quality and made in Japan. Comes with a ‘resistor’ (=diode) so can be run off 24Vac.
Not that easy to aim across a 15ft drive. In the end I held the target and gradually walked back from the sensor to the target mounting point, readjusting sensor aim a few times as required. Once on target, easy to optimise. Only been up 4 wks but looks good.
