Our true simulation uses highly scientific methods to capture impact data. Sixteen advanced optical sensors accurately measure your club through the impact zone capturing shot impact conditions and then instantaneously transmit this data through the USB cable to the software.
OptiShot has been expertly tested and is within these performance standards:
- CLUB-HEAD SPEED - +/- 2.0 MPH
- FACE ANGLE - +/- 1.5 DEGREES
- SWING PATH - +/- 1.9 DEGREES
That said, the most common cause of inaccurate or even zero swing results is lighting but Let's go over everything involved below.
Practice Space & Clubhead Design
OptiShot is basically a set of infrared emitters and detectors. If there are any other sources of infrared light in the room, then the detectors will have a hard time reading its emitter's infrared pulses. Examples of things that give off too much infrared are the Sun, incandescent light bulbs, halogen light bulbs, and even space heaters. Fluorescent and LED bulbs are the best provided they are not "daylight" or "natural light" or "full spectrum." I should point out that OptiShot will not work in dim light or darkness either.
Next we should look at the club heads themselves. Generally speaking the simple, clean, and reflective design of irons are better at reflecting OptiShot's infrared pulses back into it's detectors than the more complex undersides of some drivers on the market. Matte finish, gun metal, angular bevels, and cutouts do anything but reflect light cleanly down, rather, these surfaces scatter and diffuse the light.
If your lighting is properly set up and you are still having an issue try running OptiShot with the Swing Pad connected and turn off or at least dim all the lights in the room and observe the infrared sensors. With the exception of the Green/Red status light, every second bulb should be steadily glowing faintly red. If some are out that should be lit then the Swing Pad should be replaced.
You only need to calibrate for those clubs such as the driver that might be returning very wild hooks or slices.
When you calibrate we save your calibrated swings and attach them to the club in the club set. On each step it validates each swing to make sure the calibration is good. If we have a moderate number of swings that appear 'out of range' we warn you that we didn't see consistent input.
What is 'out of range'?
In the case of square swings - if we see a swing that is very open or very closed.
In the case of a open face - if we see a swing that is closed
In the case of a closed face - if we see a swing that is opened
How can an 'out of range' swing happen?
The exaggerated curvature on the bottom of some woods creates a curved reflection. (Picture an upside down U.) That can cause some swings to be 'out of range'.
Asymmetrical surfaces (wood with more curve or recesses on one side than the other) can cause swings to be 'out of range'.
The final step of calibration may also warn you. This message has a recalibrate, accept, cancel option.
This step analyzes all the swings for variance. If we statistically see too much variance in any of the square, open, closed steps. Then we warn you a final time.
Do these warnings mean that your calibration is invalid?
The calibration may still work and often work very well. It means that sometimes that club may give you a false reading. The more warning messages you are getting the lower the 'grade' for the calibration.
How do I fix it?
The best way to fix it is to ensure that your clubs provide a consistent reflection.
When a swing comes in for a calibrated club the face angle calculation uses the calibration data to calculate the 'true' face angle. Let's say that a club reads with a slightly open face when you in fact swing it square. (This could be due to a number of factors including offsets and other irregular reflections of the club.) After calibration what used to read as slightly open club would register as square. In a similar way the open and closed face angles are adjusted to the 'true' face angle registered in the calibration.
What about Offsets in the Club Sets?
If calibration data is available for a given club, it does NOT use the club offsets in the face angle calculations.
Correcting Hooks, Slices, and Distances
If all of the above checks out and there is no issue and armed with a solid understanding of your swing and the ball's flight in the real world, adjustments may be made in the software to bring its swing results inline.
To correct for an inaccurate face angle and hook or slice you will need to adjust each offending club's offset setting until the swing results are inline with what you would expect to see in the real world. Please keep in mind that the offset setting is merely a tool used to correct inaccurate face angle readings and is not meant to specifically represent your club's actual offset.
To begin you will need to create a custom club set.
Customizing Club Sets
To get to the place where you may customize club sets, launch into either Practice or Play mode. I suggest Practice mode driving range because of the marked distances. Then mouse over the bottom right hand corner to open the Club & Ball Menu and click Manage Club sets. Select New and give your new club set a name. Then click your new club set and click Edit. From there you may edit each of the club set's clubs.
Use the Previous and Next buttons to select the actual club you are using, take a few swings, and observe the results. If your club face is always open you could try setting the club's offset to something dramatic like -1.5 and observe the results. Then dial in that number bit by bit until the ball flies true. The goal here is to get the results to be what you would expect to find in the real world. Once you are happy with the results, move on the the next club.
Speeds and distances may also be adjusted until they too match what you would expect to see in the real world. If you know your speed for a particular club, then that should be tweaked in the software first. If you do not, then just skip editing its speed and go straight to editing the distance.
Select the actual club you are using, take a few swings and observe the results. If the results are not quite what you would expect then make an adjustment to the club's Speed Adjustment percentage up or down from 100% until the speed feels correct. After your speeds are in line you would then observe the distances each club returns. Chances are they have fallen in line, but if they are still off simply follow the instructions above as before but make changes to each club's Distance Adjustment percentage instead.
Once you get going with all of this, changes can be made quite rapidly and can even be done on the fly during a round of golf with friends.
