My buddy and I went scouting this weekend and we were both using the tracking feature on our devices. I was using onX on my iPhone on airplane mode, he was using a 1 year old garmin 64 gps that’s basically brand new. At the end of the day his gps said we covered 11 miles and my iPhone onX gps said we covered 8.5 miles.

Anybody know why there was a difference or which one was correct? Was the iPhone measuring 2d distance?

I have no clue, but how was your phone's battery life? I'm planning to use only OnX on my iPhone and curious about keeping battery charged. Thanks.

My mt biking experience has shown me that it is usually the phone that is off vs a Garmin. Your experience may differ.

Battery life is fine. I was on it all day and it used 25 percent or so. The google earth is nice but I’d you want to “shoot” a line and walk to a waypoint the gps is way easier.

Ive been wondering the same thing regarding iPhone battery life when Bluetooth pairing to an InReach.

I have an inreach. On airplane it lasts forever connected via blue tooth. Same deal tho, the more you use it, the more it’ll drain.

My Garmin 64 also logs more miles than my phone, I have no idea which one is the more accurate reading

I wouldn’t be surprised if the iPhone is measure distance on a plane? Someone has to have the answer.

My Buddy's Onyx app on his phone said we covered 17 miles, when we killed and packed out his bull in NM in 2016...I hope to Hell it wasn't an underestimation!!!

I think it has to do with the accuracy of your gps receiver. The early gps units from the 90s were especially bad and have improved tremendously. Back then if you stood still the gps thought you were moving around within a 30-50 yard circle. Current gps units will show you within a 10' circle when you're standing still. Of course, there will always be some degree of error.

For this reason some gps units will show you to be covering more ground than you actually are. If you're moving quickly (vehicle, bike, etc) you'll have less error, but if you're hiking and hunting with frequent stops the gps will add more error and show extra mileage.
