I have noticed other members have done this and thought it was a wonderful idea. I was fortunate enough to be able to get a nice new Lowrance unit for my rig so I have a good used one available. It is in real good condition with all parts included. It is a Lowrance LMS 337c DF, sonar/GPS +WAAS Comb, six years old. It has a seperate [not built in] LGC2000 GPS Receiver, adapter plate to mount unit and receiver together, also antenna mount to place receiver away from unit [possibly an unobstructed location], the T connector to connect the receiver to the unit and extra cable if receiver is located away from unit. It comes with some Lowrance maps in it and has a Navionics chip for the EAST. They are both six years old but have lots of good info in them. The complete operations manual is with it and the original box it came in. Will have to pack some items in another box, just can't stuff it all back in there and there are some extra items. I would like it to go to a veteran, current service person, policeman, firemen or someone who could use a little help to better enjoy the great outdoors, fishing and relaxing with family and friends. If you are interested or know someone who could use it please contact me.
