Looking at making the switch to Garmin. Only Garmin have run is a dedicated GPSmap for livescope.
If I am looking to run a 12" & (2) 10", one being for livescope. What's the advantages/disadvantages to running the GPSmap non-touch screens vs ECHOmap Ultras? Other than touch screen with ECHOmap.
What's needed for linking?
Is the steady cast heading sensor worth the extra cost?
