Package deal Square HE and SC 4 golf launch monitors for sale in Layton. The Square is for indoor only. The SC 4 is for both indoor and outdoor. Play simulator golf at home and see your shot data out on the driving range. Ball speed is accurate on both. The Square works great with GsPro and comes with its own simulator software as well. I used the Square for a year and a half playing GsPro in my garage. Third party leveling stand and reflective tape included for the Square. The Square includes a swing stick that can be used inside the house in any room. The swing stick is also good for children and beginners because you don't hit a ball when using the swing stick. I recently bought a Square Omni launch monitor and no longer need these. Try them out in my garage full golf sim if you want to.
