I ended up getting a Garmin GPSMAP 545s Marine GPS Receiver and also bought the chip to go with it so I'm happy.

I e mailed Garmin with a few questions and they got right back to me.

I was actually looking at Lowrance, but just to many problems.

So I did it...now we find out if it works. My old Impulse 4040 was a good easy to use touch screen unit that was a little ahead of it's time...

Good fishing and see you at Sekiu for Halibut, I haven't been out there for 4 years.
