Respect the budget or sleep aft says She Who Must Be Obeyed. Received donation of near new Lowrance Globalmap 3300 with the appropriate chart card, an X48 , some NMEA cables and a GPS antenna. Question is whether it is rational to go through the trouble of installing these dated devices, or wait and save for a used newer device such as a Humminbird Combo unit.
First off it doesn't appear to be that dated. However, this is coming from a geek who is usually 3 gernerations behind the times. Why not use it until you can afford "better".
It seems to have all of the features including NMEA connection so you should be able to send to your autopilot and VHS radio DSC emergency functions.
The only function I don't see on yours that is on mine is the depth sounder and fish finder. Your manual is available online FYI.
BTW I noticed this week that my newer GPSmap does not have the shipping lanes delineated as my older unit did. Could have used it on way back from Catalina.
I had an oil tanker in front of me and a cargo ship behind me. It would have been nice to know when I was out of harms way.
