How accurate is ONX?

I like it, but the property lines can be a smidge off-- see my pic below-- the red lines are where onx says the prop lines are, but if you look at the sat imaging, you can clearly see the fence lines/prop lines are a bit off.
Sometimes roads (mainly dirt/fr County roads) are off too. On my map pic below, that dotted white road is 3 properties over, so it's not even close to where it should be)
I've also noticed it takes them some time to update property owner info when a transfer takes placeView attachment 307982
Fence lines are not always property lines
 
Remember they will give you a general reference. These maps are not survey grade, as stated earlier they get their data from county and states offices that have GIS programs which can be off.
 
I prefer Basemaps , especially now it's linked to my Sig Kilo8k. Makes perfect sense and has been a feature I've been looking for after several hunting experiences tracking animals .

I use OnX for offloading and don't think it's super user friendly like basemap is
 
Three years ago I wanted to start big game hunting, and my buddy had me buy GoHunt and OnX and showed me how to use them. I've hunted 8 states since then and it's the best money I've ever spent.
 
I'm a big fan of OnX, don't know anything about Basemaps. Have been using OnX almost since they started. The complaints I hear on this thread are certainly problems I have encountered. The compass can be off, sure. I carry a regular compass in my pack. The phantom roads are probably roads that were on the maps during the initial survey although I am willing to be corrected on that. We were told, in Montana, that the property line is the fenceline not the actual property line. The warden pointed to a fenceline that was a quarter mile off of the property line and fenced in part of a state section. So, with my personal residence, and a cabin halfway across the state the property lines shown are exactly as surveyed. That being said, I wouldn't hunt anywhere in MT without OnX, even if I was miles deep into national forest or wilderness. Found it helpful for access points, elevation change, ranging, keeping track of wallows and rubs, crossings, trails, etc. My favorite place to hunt/hike is in South Central MT. Access is a narrow corridor between private land that just touches a public road. There is no way I would hunt or hike in there without knowing where the property lines are. We have been able to access previously unknown tracts of public land with it. It is a great product and I have had great luck with customer service. Can't recommend it highly enough.
 
Three years ago, on a Nevada pronghorn hunt, used OnX alot.
In one case, we lost the two-track road we were on. It just disappeared, having not been driven on in years. Yet, it was on the paper map, and OnX. Walked out about 50 yards and moved around watching the OnX map road. Eventually, crossed it on the map, and looked where we stood. There it was, right on the money! We could barely see it, but OnX had it all along.
But the best was two pronghorn bucks vying for a harem of does. They went back and forth for 5 days, from two private property meadows. The big one chasing off the smaller, then returning to the herd. Then on day, I went around a mountain on BLM land, stopped at the base, and watched the show. Finally, the big one chased of the smaller way past, and far from the herd, into a third huge meadow way north. And OFF of private property. OnX (and paper maps) confirmed that I was well within BLM, and that the two had just cut across a corner of BLM.
On the bigger buck's return, he met with 168 grains of Nosler. Right in the BLM corner.
I believe fully in OnX and my experiences with continue.
 
It's worth it. Try it for a year or even the free trial period and if it's not for you don't renew. Very valuable in around private but also for access and satellite imagery/topography. I mostly hunt public land but occasionally a private access issue comes up and onX will give you the piece of mind needed to continue on without worry. I switch between inreach's Earthmate and onX and find onx features to be superior. The new 3D desktop version with map overlay is also amazing and worth checking out if you haven't. It's like google earth with trails roads and topo highlighted. Extremely valuable info espescially if your not familiar with a certain area. No brainer.

Keep in mind fence lines are not always accurate property boundaries either. On some property I own the fence line on 2 sides are 30ft off the survey pins.
 
I use avenza with downloaded Forest service topo maps for navigating in NF and State/dnr lands, no need for cell service. I have OnX hunt and offroad and the property lines are close enough to use common sense to decipher where you should and shouldn't go. Offgrid map downloading is a pain. Ironically the property lines are the same as the county property line maps, they are both just as far off compared to the actual property lines since they do use the county maps to show boundaries.

I don't find downloading the offline maps to be difficult at all. If you don't mind low resolution maps you can download maps 100 miles wide.
 
I think OnX on phone is a must product for us hunters. It show unit boundaries, state land that is closed to hunting, Forest, BLM and who owns the private as well as all the other mapping features. Best part about the phone app is it is continually being updated unlike the chips or other programs you can buy. I have found them to be accurate for the most part, but it will show some roads that aren't open or trails that don't exist. Best and worst hunting device ever. Makes it hard to keep secret when everyone can find water holes (important in the SW)
