I keep records, My HB units play out in a couple of years.
My latest HB units last about 2 +- years, they are hooked up correctly and the battery power is 12.3/4 volts. Is it just me or are other people having the same problem??? This makes it hard to invest in the new units. I know I will get a lot of flack but It is serious money to me. I am retired and would like a unit to last a few years. Please, do not right that your units last for 20years, and so forth. I am talking about the new super units. P.S- I do fish a lot and put some hours on my HB units. P.S - My Ray Marine is 5 yrs old and going strong.
