What additional features does Navbox Pro have for VFR flight which justify the much higher price?
Main one from my perspective is that it has a GPS interface... so I can easily knock up a plan, print the PLOG, and with a few extra clicks I can also have the route in my GPS-III, which obvisouly avoids making silly errrors with Lat/Long etc. It also lets you see your track form the GPS when you return, but I use
www.goflying.org for that these days.
