Garmin Vs Lowrance
I had a Garmin 89 for years & recently got an airmap 500. The AirMaps menus aren't as intuitive as the Garmin & the LCD contrast is poorer which makes for harder reading because they also use a smaller font than the Garmin.
The airport runway orientation feature on the Airmap is nice but, if I had my time over again, I think I would go Garmin.
