I have a Bottomline HR , That came with my boat. I still have it, but I had to send it back to them 2 times. the first time the power button went bad, and they charged me 89 bucks. The second time was less than a year later, same problem. that time they fixed it for free, and upgraded some internal parts. besides that its a champion. I like the big screen, with extra large #s, you could read it from across the boat.
