Simulator Club Gapping Service

[BTatHome]

I've had a response back to my query now. You're right the smash factor and ball speed are standard figures and should be ignored - the reason is that to get these readings requires the HMT system at an extra £5k! Primarily the system is for club fitting and the GC2 clubhead speed reading is accurate to 0.5mph - can't say I blame them for not wanting to spend the extra money.

Yeah I seem to remember reading that they use special balls with dots on them to read ball speed, hence why they require specialist extra kit.

as stated in the later reply the club head speed is being measured and the ball speed calculated.

Btw surely your driver will be the highest speed, simply because it has the longest shaft, unless your description of 'further down the set' actually meant driver rather than wedges

What I mean is the clubhead speed will be reading lower the further down your bag go go ie with your wedge if you are hitting 100mph ball speed then dividing this by 1.45 will give you a clubhead speed of 69mph where the smash factor should be closer to 1.23 so divide 100mph by 1.23 (assuming a good strike) and you get a higher clubhead speed of 81.3mph. The further up the bag you get, up to a 3 iron which should have a smash factor of 1.45 (assuming a good strike) then the clubhead speed on CG2 will be closer to your actual clubhead speed. Once you go past a 3 iron the clubhead speed on CG2 tends to read high. As for example you have a driver ball speed of 150mph then CG2 will give you a clubhead speed reading of 103.4mph where it should be nearer to 100mph (150mph divided by 1.5) again this is assuming a good strike.

Are you sure it's that way round?

If the software is calculating ball speed from club speed x 1.45 then your iron distances are going to be way out because a decent hit with a 6 iron will be club speed x 1.3 ish.

If the club speed is being calculated from ball speed / 1.45 then club speed will be wrong for irons but at least the distances will be right.

This isn't right. Indoor Trackman uses balls with a silver dot to measure spin. The GC2 measures ball speed without any dots or specialist balls and calculates an estimated club speed. The HMT will measure the club speed and other parameters.

Good point. It must be as the camera is focused on the ball to get the launch conditions information (spin etc) and not the club.

When I had my fitting done last year (before they had the GC2) the initial shaft information was sourced from the Mizuno dna device (as a starting point only). I guess that they don't really need the clubhead speed information after that. I recall that the fitting was then concentrating on what the ball was doing in reaction to the club/shaft combo I had in my hand (and the dodgy swing I was putting on it of course :fore

Here's a link to the bit of kit that they use: http://www.foresightsports.com/products/performance-simulation

The range at Maidenhead I use offers this service. I've been tempted on several occasions. They do a four club gapping service or you can do the whole bag.

Interesting, do you know how much they charge?
