The searchlight should be used on my yacht. Whether the range of the searchlight will be sufficient, I can only say after the 16.04.2016 (watering the ship after the winter camp). I hope the beam goes far enough. Specified are 800/100 meters.rnNow, it should be noted that the mounting instructions of the searchlight is very incomprehensible and a test commissioning was possible only by correspondence with the company SVB.rnDesweiteren is to say that the manufacturer urges the installation of two fuses, Unfortunately, these are not included in the scope of delivery and of this fact, the buyer learns only when he has received the goods. A quick, safe installation is not possible.rnAnother small flaw is that the screw holes on the control panel are different sizes. I had to drill four of the eight holes.
