Keep in mind, too, that most of these receivers use the same chipset. So the GPS performance is going to be similar, if not identical, with fast 10Hz updates and 32-channel, high-sensitivity receivers. Mostly be concerned about physical characteristics; type of mount available, cable compatibility with your existing infrastructure, and the ability to update software via a compatible chartplotter, if possible. For the cable issue, I chose the Simrad over the Lowrance, as it comes with a detachable, fully NMEA2k compliant cable which is longer than the Lowrance’s (I believe attached) cable. And as far as the current draw goes, anything under 100ma is negligible. The Simrad also gives you the heading sensor, which the Garmin does not.
