need a kind GPS GUY!!

[lroberts]

If you get the Humminbird GPS capable unit and receiver all you need from there is the chip, whether it be Navionics or Hotspots map. I would get the newly updated 2009 model. You will need a chip for each unit...if you have multiple GPS units on your boat. For instance, many guys have one up front and in the console. Good luck!

Check out the BBC website for electronics, one of the guys there also has a yahoo forum that he uses to discuss and teach the Humminbird. Also, if it is a side imaging unit bfhp (bass fishing homepage) has an area dedicated to electronics and a gentleman(LTBAMA) posts pics all of the time with explanations on what the indications are.
