looking for new GPS
I like it. Garmin 162 fixed mount with external antenna (decent sized display, will accept blue charts if you want, has a nice GPS data display and tides), with Garmin GPSMAP 76 (or 76S) will accept same blue chart and similar technology. You get redundancy, same manufacturer (so similar user interface) and still under $1K. About $350 for the 162 and 300-400 for 76, depending on model.
