Humminbird Matrix 67
I have been using a Humminbird Matrix 67 for a lot of years out of a kayak for my offshore trips. The unit has worked great over the years and has been threw a lot. I keep it clean and it keeps working. The last trip out the unit was not showing bottom and said That I was in 1220 feet of water, when I was in 30 feet. The GPS works great and helped saved the trip by putting us on marks in 220 feet. I think that it may be the transducer. Love to here what you think. Thanks.
