I was the proud owner of a LMS 337 C DF Lowrance GPS/ SOUNDER until it had probs with the brightness control , going from black to full brightness every second. Not the kind of nav aid u need around reefs at night. I contacted Lowrance and didn't have original receipt as unit was fitted in boat when I bought it.I had contacted original owner for proof of purchase, but he could only say he bought it about 2 years prior.I passed this on 2 Lowrance and after sending them my old unit they sent a new replacement, the latest model the 525c df. When companies back their products with fair treatment of their customers, I'll give them a plug. I speak only for myself, and without favor or profit, to let companies know that good customer service brings customer loyalty, and yes, give me a good product with good backup and I'll be back!!!!!![]()
