BaseMap does have some features I wish On X had - like giving you a compass azimuth when you want to go to a waypoint instead of "984 yards SSE."
The detail of their satellite images is better than On X as well. However, their land ownership isn't as up to date.
I promise this isn't a boomer anti technology post.
I have basemap, gohunt, onx, scout to hunt, and probably some others. I hunt multiple states, doing usually deep in expedition type hunts. So, e-scouting is important. I simply don't have time to drive around western US to scout. I don't even know what states I'll draw, which gives me less time.
Hence why I still opt to use a paper map. I have onx in a garmin series GPS for land ownership.
All my scouting on gohunt just gets transcribed to
the map and/or the GPS, so everything satellite related is done at home and not in the field. As if I would have signal.
Azimuth can be determined on the map. Declination is on the map if shooting an azimuth on the compass. So no need for true north, just a standard grid to magnetic. Map holds my notes as well. For me, it's easier this way with more accuracy. Once I'm boots on ground and going where I mapped out, the satellite imagery isn't really relevant anymore. I've already executed a decision.
