Launch monitors

Hey

I went to my golf shop the other day to play on their launch monitor with my driver and would like input on this deal.

I am using a cobra sz 400 10.5 reg.flex (best club I've ever hit)

Launch angle was 8
Swing speed was 106
Carry distance was 267 with draw
Ball heigth was 37 yds.
Center clubface with 1-2 deg. outside-to-in

Do these #'s seem right ? 8 deg launch with 37 yds height? They had a chart that showed I should be at 12 -14 deg.Anyway, he said don't mess with anything.LOL- but that still didn't answer my how I'm hitting a draw with a slight out to in path with a low launch angle and a fairly high ball flight.

Just a curious question for the pro's

The launch angle is always less than the loft of the club, a 10 deg driver for example would normally create an 8 deg launch angle. Physics has an answer for this and I would need to refresh my knowledge if you wanted to know why.

The flight of the ball is also reliant on some complex physics. for example a hit near the toe or heal will bend the flight, an open or closed face combined with the hit position bends the ball flight differently.

Hey Brian

Congrats on being a grandpa,

So are you saying I should leave this part alone like the guy in the shop did?
Are these decent numbers not to worry about?

P.S.
At the range today there was a guy hitting balls for the first time-he made some good comments on my swing -so we chatted for a bit-watched him hit some balls-big time SWAY.I said I don't like giving advice-BUT I will give a tip.(And that was keeping the weight on the inside of the right foot.)(Which has helped my swing tremendously).
Any way that tip helped me and I was glad to pass it on and hopefully help someone else.

P.S.S.
He did hit the ball straight

Hey dawg,

Those are some odd numbers you've put together - 8° launch giving up 267 yards? That can't be all carry, can it?

As for brian, he's talking about gear effect - why hitting the ball on the toe produces a draw, and heeling it produces a fade (assuming that the face is square to path at impact).

It's got you showing a pull-draw, and getting ~270. Does this match up with what you do in real life?

I think if anything I have a push draw-and I can believe the carry distance-short to some but works for me(I try to swing within myself).

I have a strong grip and am thinking I hold it off after impact and not release until half way up.The driver is probably the club I can trust the most-just hang it out the there to the right and watch it come back in about 10 yds.

I'm not saying you're short - I'm saying that the carry is incongruent with the LA from what I've learned - espeically at a few notches over 100. I've got a similar swingspeed, and carry the ball 240 on the course (GPS verified). Now, I've had some animal swings and some 300 yard drives, but swinging within myself and getting a decent ball flight, 240 is my average carry. My SS is 105-108.

Now, granted, I hit down with the driver (I have ~ 10° LA and play a 14° driver), so I may be over-spinning the ball causing distance loss... but 37 yards?

I mean, if it's working for you, don't change! That's message #1. Message #2 is 'you can't always trust a sim!'

I say it too often: If it's golf club shaped, you can play with it.

For the record, I'm a club doctor, not a swing doctor.

Hey LP

I think I will go back today just to double check some things-what do you think would be ball height for those #'s? Is 37 yds. too high or low for the carry it said? I don't know alot about this and you're right about not always trusting these.My biggest thing was the 1-2 deg.out to in path with a center hit producing a draw.Maybe I do alot of manipulating the club-I dunno

Thanks

It's tough, as we don't have too many vertical references in yards. Nobody says 'that house is 20 yards tall'.

Also, after re-reading the first post, the guy is a bloody idiot. In a proper driver strike with a conventional driver (ie no GRT) two things should be true:

Your Angle of Attack (AoA) should be positive. This means you're catching the ball on the upswing. Combined with this, you should be hitting the clubface mid-to-high. This adds more loft and reduces spin. Both of these things should be increasing your launch angle (LA). Therefore, your LA should be greater than your stated loft. (Also bear in mind that tolerances are +/-1°; so your 10° driver could very well be an 11, or a 9).

The other thing about most monitors is that path is relative. In other words, you could be swinging square, but if you setup open, the monitor will read it as out to in. Setup closed, it reads in to out. (This are for impact-type monitors). For ball flight monitors, again, you still need to setup square to it's read path.

Hi Dawg,

Thanks for the comment, I am proud to be a Grandfather but am not so keen on sleeping with a Grandmother Looking forward to coming over to Chicago in April and holding the little man.

Your driving distance is very commendable, nothing to be concerned about there as long as they hit the fairway. Glad you were able to help someone else.

They had this thing angled to the left because it was on the right side-and I remember having to adjust my stance for this-so that could be the reason for the out to in path-plus I found out that this monitor is not the greatest machine.I do hit the ball high for me and the carry I think is close.But I need to go to another place and see.I don't remember the spin rate-but anyway I will check some place and get back with ya.

Thanks

Low:
At the back of Golf magazine there's usually a column about 2 dudes that have bought new clubs. They usually show the trajectoy and distance between the old setup and the new. I'll look a few up and we'll see if these figures add up.
I'm always suspicious of launch monitors especially at a golf store. Like they're going to program the things to come up short? I don't think so! If you're buying clubs, always bring the old set for comparison, with a notebook of your distances over the last little while.

Just watched Tigers's swing and spec's at the end:
Clubhead speed: 132mph!!
Ball speed: 180mph!!!
Trajectory: 7.4*
Distance: 295 yds
