Question about Eagle Intellimap 640c Marine GPS GPS Receiver

1 Answer

Eagle 640c Fish Finder dosen't read corectly.

Start up normal, when on auto depth range and sensitivity gives me a normal picture as I move from shallow to deeper water. Once over 50 to 80 feet of water the unit flashes the last depth and changes to 0 - 5 ft range and shows no top or bottom. Once back to shallow water comes back into the proper range. Temp and all Radar functions work normal.

I had the same problem and got the transducer changed. It now works perfectly. That could be the problem you are having... bad transducer.

Hello! Do you have the PDF users guide for your unit? I'm looking at a copy in the troubleshooting section...I don't want to cover information you have already looked at or tried...Since I do not know if you have that manual I'll give you a few items to check...

Measure the battery at the units power connector...Must be at least 11 volts DC...In portable mode it uses 8 D cell batteries= 12 volts
Make certain the Transducer is securely connected...
Did you use the in-line fuse supplied with the unit?...
Try the Manual Depth Range...First turn off Auto Depth Range...From the sonar Page Hit MENU...Down-arrow to Auto Depth Range...Hit ENT...Hit Up-Arrow to Depth Range...Hit ENT..
And the Depth Scale Range appears...Up-Arrow or Down-Arrow to select a different depth range...Hit Exit...The minimum depth the unit can read is 5 feet...

The depth reads 98 to 100 feet.


I need more details about the problem you are having to be able to help you.
My best guess is that your unit will only disply data between 98 and 100 feet?
If thats the case check the range setting on your unit. It may be set to only display that range. You can set it to auto and it will automatically adjust the range from zero to just over the maximum depth it is currently reading.
