Hey guys....my skytrak came in yesterday and I set it up. leveled to the mat and aligned to the center of the net. The issue I am seeing is with the numbers coming from the device. I dont mean "oh its 15% shorter than IRL" I mean I am seeing REALLY weird numbers. Over 10K backspin with a 5 iron. well struck balls going 100 yards. I have had the same results with my 7I. this is in daylight, but under a covered area. Note a couple of really strange ball speed to club speed numbers. I think the height of the ball flight is also extremely low. Can yall take a look and let me know if there is something I am missing? Any suggestions are most appreciated. The Mat is the 6x6 home turf that is part of a package deal from Skytrak and I am using a less than stellar golf ball. Can a mediocre ball make that much difference? Do I need to call Skytrak support?

Speaking with them first is always a great shout, you bought their unit so use there support team to guide you its what you pay for better to take advice here first I would say.
Numbers are completely out from what I see here, Bright sunlight can interfere with it out doors but speak with support and they can check your system for you -
Try it when it’s dark out and see if the readings change. Then you can rule out sunlightComment

Even in the shade sun reflection from objects will cause what you're seeing. Best is put the top of a box of balls over the SkyTrak like a baseball cap and try again. Make sure there are no reflective surfaces behind you.[url]http://www.24-7.golf[/url]

Just wanted to update. I flipped my setup around completely. I had a white refrigerator behind me and in the line of site of the Skytrak previously that I believe was causing some issues. This also places the unit in a more shaded portion of the covered hitting area. I also placed the unit on the mat instead of beside it and only need a small piece of cardboard to get it very level. I also believe the unit doesnt deal very well with lower club speeds. I am 6'1" 175lbs but I dont swing very hard. I think there is some over penalization in the algorithm for slower club speeds. Since one of my largest goals with the unit is to learn to increase my club speed, I started swinging harder today along with these other changes. The numbers are much better now and I do not think I have a defective unit. These numbers are still short of actual, but by an amount that is reasonable and the thing certainly knows when I strike the ball purely and when I do not. it definitely knows when I hook it, or swing from out to in. So I am building some trust now. My biggest issue now is that it occasionally reads crazy backspin(i.e. 11k backspin with a 5 iron). I think this could be some of the really crappy balls Im using right now. I went and and ordered some bridgestone e12 softs and will try to consistently use the same ball.
thanks for all the input. here is today's practice with the 5 and 7....I also did a bag mapping which was very informative and tiring as I did 10 swings per club

Those numbers seem reasonable. With skytrak just ignore clubhead speed it is calculated NOT measured. Most important numbers to concentrate on are Ball Speed and Spin (back). The issue I see is the spin is quite low for a 7 iron. The carry distance is accurate and as you can see the unit is calculating significant roll out to get you to 147 total yards.
General rule of thumb is approximately 1000 x iron used ( 7 iron would be 7000 .. give or take 500 I would say is reasonable). Now the mat, your ball striking and of course the ball will affect these numbers. Skytrak does not do well with colored golf balls and may exaggerate spin over 10,000 with a 5 iron. Large logo bridgestone in white is a great ball to use. Just face the Large B logo towards the unit.
Btw don't get too hung up on distance. Hitting in a sim is like golf in a vacuum. No wind, no elevation changes, no humidity, no flyer lies, etc. Most people think they know how far they hit the ball but those are assumptions. Par 3 145.. guy may hit 8 iron to center pin. lands and sticks left front of green. Wow... green in regulation and 15-20 footer for legit birdie look. Problem is we are conditioned this way and when we sim on a launch monitor that 8 may read 135 and you get deflated. the reality is that's what you really hit the iron.
Skytrak is really accurate, just concentrate on flight and shape. Good luck

Well put! I wonder whether we sometimes get so caught up in numbers that we lose the feel of a golf swing. Before we had all these great systems to allow us to see shots indoors we were on the range hitting balls no spin data no club data and just the flight and strike and the outcome to decide if we were happy or not and what changes we made to improve that result. data is very useful if you understand how to apply it to your own game to degree everyone can play better golf and improve just getting better at what they do well and improving what they dont.
So many ways to play this game! How do we really know what is accurate? Every system says something a little or a lot different but often the end result is about the same.
Most do not really know how far they really carry a ball out doors so how can they be sure what is correct indoors. In a simple term, if you hit a ball outside that on average has a particular shape and flies a particular distance and this is seen on a 500 buck system or a 50,000 buck system would you class one or both pretty accurate?
A big benefit of having a sim is the facility and ease to hit more balls and make more swings more often and providing a system does not show the opposite to what you do outside then or something completely different then its a useful tool to improve your game.
Personally and being a pro for over 20 years I know what my average club speed is with any club in the bag. Could I tell you what my average ball speed and spin rate is No! Much of club speed is down to the ability of the player, I know I can work on that and I can control that to a degree. I could change ball tomorrow and get something different, Equipment plays such a big part in ball speed and spin and changes so much as do we the player over time.
If i can use a system that does a good job of replicating a shot that I am used to seeing then being able to repeat that and more often is most beneficial.
More intricate info is great for professionally trained people to advise on best matching equipment to a players needs and characteristics.
With regard to the above, it is said that the 7 iron seemed accurate but spin quite low and ignore the speed as its calculated but the shot outcome seemed accurate.
The club speed is calculated so ignore it.
Whatever the the factors were that gave a pretty accurate result for the player can still be taken into account to improve.
Lets say the club speed calculated was 80mph and the player wants to increase speed then at least they have something to use to see an increase whether totally true or not so for this it is still quite useful.
If the player wants to work on that and told ignore it focus on ball speed an spin then they lose that reference. You could in theory lose ball speed if the equipment is not suited.
This is why people have ball fittings for example where ball speed would be very very relative in that scenario.
I love tech and love the benefits it can bring used in the right way and with the right understanding of how to apply it.
I have seen posts talking about what sim is most accurate and posts saying X is more accurate than Y but i think it is subjective to the individual as we do not really definitively know which is the most accurate.
I recently ran a low cost, mid cost and high cost together and saw each one replicate the shot I hit very well. Each one gave a different spin, ball speed and club speed, 1 unit looked and head and ball, one was ball only and one was head with calculated ball and they were not that far off each other in terms of data but launch and flight were very close distances in carry to within 3 yards (9feet!) of each other. Would you class any as inaccurate? how do you decide which ball speed, club speed etc was the closest to the real thing. If I were 160 out and hit all 3 to within 9 feet I would be pretty satisfied.
Every system has its pro's and cons and glitches, units such as Skytrack have made having the ultimate golfers toy for many achievable and sometimes I see comments on here that would put a major downer on people who have spent what they could to get something they want to enjoy only to believe that they have still spent a large some of money on something that some may personally class as rubbish.
In general, If any system shows near as damn it what you hit on course and gives you data whether it totally correct or not, it is still very useful to gauge improvement and offer a base to work from.
I originally purchased a mid cost system that gave me pretty good and realistic outcomes close to reality. I was fitted for a new 3 wood with a top and well known brand for the fitter to swear blind the data was bang on even though I never carried a 3 wood past 210 yards! I think i was 11 years old when I hit a 3wood past this on a regular basis but he swore blind it could not be wrong as the data from the system was the most accurate on the market.
I say, if you have a system that replicates what you do pretty well then enjoy and use it to best effect you can instead of doubting everything about it as you will not get any enjoyment from it and you will rob yourself of the chance to improve and enjoy your game more.
Golfers of all types try and seek perfection and I see this also when it comes to golfers and golf sims, irons , woods, putters, the list is extensive well good luck with that one.
If anything was perfect it would never need improvement and the fact that things change all the time in search of improvement says that nothing is perfect
If we asked everyone what would there perfect sim would be like and do for them I wonder if we would all say the same, hell tons of of money is spent on ProTee software and tons still only want to play and use Protee 2.0!!! old but still has useful features.Last edited by PROTEE UK; 06-14-2019, 11:17 PM.

Lynchdpm nailed it. Skytrak is more accurate than you'll want to initially believe. Unless you've been meticulously measuring all of your carry distances, most of us have been using our total distance as the reference on how far we can hit.

Also make sure your laser dot is about 12" from the unit base.Comment
