I just purchased an Oregon 450 and I'm somewhat new to TOPOs, my old unit was a Magellan sporttrack, got me in and out with other features. I want to load some topos for hunting and was wondering what program would be best. Do i need garmin topo, Delorme 9.0 as my base or can the TOPOfusion program do it all for me. Needs would be topo detail, aerial photos, waypoint marks and tracks. Any insight? Thanks Scott for the email response!
