I bought in to all the hype a year ago about the Lowrance products and spent close to $7K worth of equipment including a HDS8, 10, broadband radar, fuel flow, gps antennas, structure scan, etc. The last year has been a total nightmare!!!!
1. My units were turning off and restarting on its own, usually at the worst times
2. My units would turn colors, red, blue, black
3. I had constant clicking on my vhf
4. Interference on my TR1
5. VERY slow redraw

I called Lowrance over and over regarding the problem. Most often I would sit on hold for over a half hour only to have some rookie tell me that they are new and couldn’t help me but a manager could call me back. I can’t tell you how many times I was told a manager would call me back and never did. Therefore I was on my own. My mechanic spent countless hours rewiring the boat, changing out cables, new circuit breakers, new vhf antennas, etc.

We narrowed the problem down to the HDS10, when the fuse was taken out the clicking on the vhf stopped. More calls to Lowrance, more messages left and no return call. I finally ran into a tech at the boat show and he told me that there has been a bulletin out for over a year regarding my exact problem and that the NEP1’s (network expansion port) was defective and needed to be replaced with a new NEP2. So I call Lowrance and again get a newbie that says “what is a NEP?”. Anyways, months go by and I get the new NEP2 but the problems are still there so I say f**k it pull the NEP and wire direct, problem solved. Now I cannot get Lowrance to call me back regarding the return of the NEP, I have logged 11 messages over the last 3 weeks and still no return call. I spent over $3K in labor trying to fix the problems caused by Lowrance, trust me it is not worth the hassle. How can all the people I talked to about my problem not know of a bulletin put out by their own company?

The HDS products are awesome when they work, but the customer service and product knowledge of the reps SUCK big time!! I wish I would have bought Garmin or Furuno. Again let me say the customer service at Lowrance is the worst you can ever imagine and their reps know nothing about their products.
