HUMMINBIRD 587 CI HD COMBO

[steelydan]

while trolling on seneca the other day my depth on the screen kept reading between .8ft and 4.5ft deep. i was in 190 to 230ft of water. every 5 min or so it would read the correct depth for a min or so. does anyone know what is wrong with the unit or have an idea what to do? please help.thanks and tight lines.

I went thru this with my 788ci , you will need to change some setting. Go into advanced mode and change from fresh to salt water. Take a look back at my post and you will find a detailed plan of what I had to do to fix it. Also it could be the transder going BAD if the color is starting to fade some.

Similar thing happened to me. check the sound coming from the transducer. it might be bad.

That happened to me also with the same unit but noticed that we had the bottom set for a max of 60 feet and when went over 60 feet, the graph would show the difference between the max depth we had set and the actual depth. In other words when we were in 65 feet of water the graph would register 5 feet, 68 feet of water, the graph would register 8 feet. I think it's a setting you can adjust.
