I went to the range today and hit a large bucket of balls and measured my clubhead speed with my swing mate meter.

With the Swing Mate speed device, it told me my clubhead speed was 112-121 mph with a driver. I had a Bushnell range finder and shot the trunk of a group of trees at the back of the range at 256 yards. I was consistently flying the ball into the tops of those trees.

Later today, I went to a golf shop to buy some grips and they had the same Swing Mate swing meter in their indoor hitting room. I couldn't even come close to what I was swinging outdoors earlier. I only swung 99-108 mph indoors.

Which is right? Why such a massive difference? Does the psychological effect of hitting inside slow you down?

My carry distance is about 275 on average with a well hit driver.

I swing a lot faster outdoors, probably somewhere between 5-10 mph.

I wouldn't be surprised if it's a variety of factors, ranging from lack of a proper warm-up, odd environment/setup (mat, ball teed up differently, etc), and if I'm focused on the #'s vs. a clean strike with a good ball flight, my mechanics start to break down. My backswing also tends to be a little bit flat, so even the stupid wall that's behind me will sometimes come into my mind when I'm hitting in these bays.

Also could be that they were different swing meters, assuming I read what you wrote correctly. One might not have been calibrated the same as the other

Yeah, Im just guessing they're calibrated differently.

They might be calibrated differently, but I think most people are going to swing faster outdoors. I've used the same portable device indoor and outdoor on the same day, and I swung at least 5 mph faster on average outdoors.

I believe I read somewhere that Bubba Watson has the highest recorded club head speed on tour at around 128. If you are swinging 121, you are a beast.

I used to love when people used to come into the golf store and say they had a swing speed of 110-120 and our Velocity would pick them up at 95-98. Granted its not perfect but when you see it so many times gets very hard to believe. Probably your device
do you have an x flex in your driver?

It's kind of surprising that Watson, Woodland, and Dustin Johnson can't get it up to 132-135 when they really need it. I wish they picked 1-2 par 5s per week on tour, and the broadcast showed the monitor readings.
