We purchased new property a coupe of years ago that is still listed under the original owner. I think they only update their database every two years. Like most of these kinds of software, OnX takes a bunch of non-proprietary data and reorganizes it into a palatable format. Farmer Dan hit the nail on the head. The problem is sh!t in, sh!t out.
With that having been said, I can get to within a couple feet of the survey markers using their maps. I also like the trail mapping feature - it reminds me of Alltrails, which we use out West when we're hiking the National Parks. Great way to navigate in the dark, particularly if you've forgotten to replace the battery in your headlamp or you lost the markers on the trees. And my buddies like that I can share landmarks (stands) with them, so they know where they're going.
So I will weigh in on the positive side, with caveats. I'd be PO'd too if I were Bill, though.
I'm offend! If you would have, first, at least read my couple of posts you would have been more well informed! Then, you would maybe understand why "....they suck" and, perhaps, have expressed your indignity with more enthusiasm!
The only problem with it, and I have it as well, is the property lines are not very accurate. Both my house and my property (in two different states) are considerably off. Especially my property. According to it, I own a good bit of my neighbors land which is awesome!
I feel like they really hone down property lines out west because that is their bread and butter while the East gets little effort.
Same with me in Ohio. My property was just surveyed about 18 months ago and if I stand at the corner post it shows that I am a good distance onto my neighbor's property. It also is out of date by a couple years in my area as well. It still shows the previous owner on a 30 acre piece I bought 2.5 years ago. This may be my county's fault and not OnX, but just be aware it happens.
We bought land from the government. It took me three months of emailing/calling OnX but they did get the map changed so it no longer shows public. HuntStand has been more difficult, still not changed.
