Why do range balls hit off mats typically go so much higher than the same balls off turf? This happens to me frequently and I don't know why. We have good mats at my club, but the balls balloon. When I hit them off grass, no ballooning.

Probably more difficult to get the dynamic loft lower on the mats.
Just my guess.

When I'm striking the ball well on the range (always off mats) the ball impacts the face in the center, both horizontally and vertically. When I hit the ball well off grass it's centered horizontally, but lower on the face.
More weight below the impact spot off mats, higher launch and typically further. Off grass the ball flight is a little more penetrating.
Just thinking out loud.

The ball jumps more from that rubber based matt than from the ground. So that part of the pressure which is downwards gets it bouncing.... and once again confuses radar systems  |

I suspect the ball might jump a little more right before first touch. Must be nice to practice with Pro-V1s all day long like the tour players on grass.

Doesn't this Phantom video provide the explanation?
The mat is softer than dirt, so the club face gets under the ball easier, making the impact location higher, producing higher ballflight.

Part of my thinking was that there is less resistance from the mats than the grass.
Look at Mike McNary's overtaking rates off grass vs. off the matts:

Absolutely. Hopefully I'm not hitting the ball THAT fat (it was a flop shot in the vid if memory serves... so a-ok there), but I have almost no chance of hitting the 3rd groove when practicing off mats. I think the vid helps to explain why. I've never heard anyone talk about it though... I've talked with some really good golfers at my range and no one seems to factor it in when looking at traj. EDIT: "Lob" is in the title, missed that. My memory serves after all.  |

I've only had one person ask me this question before. I just said that it's most likely due to the range balls which are designed to spin a lot more than your normal golf ball.

The video posted by Jeffy is helpful. I don't think it's the ball. I can take range balls off grass without the ballooning effect. Really noticed it the other day warming up.

It just doesn't explain why it launches so high even I make good pressured contact with it. I still think it's that tight and flexible base that makes it bounce. At least with those matts that we use here it's not at all possible to get that happen that happens at video. They feel more like hardpan than grass. |

What "gets bouncing"? I'm not understanding.

What "gets bouncing"? I'm not understanding. In good shot there is always part of the force against the ground as the club is mowing downwards. Also there is some pressure against the ground when ball changes its shape at impact. That's why it's also acting differently from different lies. |
