I was having trouble with my Raymarine Radar and I contacted Langer Krell for warranty repair. They came to my boat the next day and determined my radar had to go back to Raymarine to be fixed. It took a while for Raymarine to turn it around but as soon as it came back Langer had it on my boat the very next day. Unfortunately, the radar didn’t last long as my power source ended up being the problem. Bobby Krell himself called me and assured me they were going to get the problem fixed and have me up and running before my next trip. It was no easy task but Langer Krell kept true to their promise and bent over backward to make sure I was up and running. Great outfit… I highly recommend!
