4 Club Difference in Distance

Hello All,

This is day 2 of owning a brand new R10. After months of anticipation and high hopes, I'm pretty disappointed. 

All of my clubs are 20-60 yards short. I am outdoors hitting into a large net. I've moved the unit forward, back, up, down, tilted down, and titled up (Re-Calibrating after each significant change). I've also moved the hitting mat, removed the hitting mat, and finally moved the net without any success. I updated to 4.0 via Garmin Express but made no difference. I tried Home Tee Hero and the E6 driving range as well but the inaccurate readings continued. 

What else can be done on my end? I really want to make this work and believe it is user error but as the hours of experimentation/frustration go by, I'm thinking it's a dud unit. 

I understand taking it to the range is an option but I bought it for the backyard so that seems rather futile. 

Appreciate any and all suggestions!
