GC2 outdoors

[Keyser]

Has anyone used GC2 outdoors and tested how accurate it is compared to actuall ballflight?

[mthunt]

Yes. Lots of times. Extremely accurate

Testing outdoors for carry accuracy is hit or miss simply because your ambient conditions and topography may or may not be the same as the ones used in the ball ballistics computation.

That said, on a calm day the carry distance is accurate. I'd note it may be hard to tell with longer clubs since you may or may not be able to accurately see where the ball landed and measure to that spot taking into account up or down tilt of the land.

I've had mine outdoors with a Trackman for a side by side comparison.
When you set Trackman to have no wind, they are near on identical.

Ive heard from a user that randomly he'll get shots that are up to 30y incorrect laterally.

30 yards? I use mine outside all the time. I've never seen that once. The user should get his device fixed.

Same as trackman except on spin whereas GC2 is always lower for some reason.

The reason is most likely that a GC2 has much lower published spin error tolerance then a Trackman.

I'd think that this would then be a +/- thing, not a constantly lower by some range thing.

Either way, I'd expect them to be close.
