I have a Lowrance 17M. it takes all the navionics charts and can use
mapcreate 6 to make your own charts.

We have a 22' boat. Already have a GPS, the basic
hand held Garmin - no mapping - no color screen.

I'm thinking I'd like to get a hand held unit that
has charts/maps with depths. I'd like it to have a PC
interface.

Any good models you can suggest?

What features, etc. should I be thinking about?

Thanks,
Gary
