Very bad
Don’t get does not work even with calibration!
Level
To me is the best tool
Percentage slope is helpful for golfers who use AimPoint
I would probably use it sideways for measuring slope on a green. Make sure your phone doesn’t have a lens sticking out. A reason to keep an older or cheaper iPhone.
Greg superintendent buildings in Brooklyn great idea and engineered Well . Thanks
Convenient and performs well!
Not good
Calibration never ends
