Frequently Asked Questions

Q:  Can I use Slopegraide only with my Apple Watch or do I need to have my iPhone in my pocket?

A:  Yes you can!  As golfers ourselves, we know how much distraction phones can present to yourself and others on the golf course.

 

With this in mind, we designed Slopegraide to have the ability to be used with either an iPhone or an Apple Watch.  

 

However, you will need to calibrate the Slopegraide sensor first using your iPhone.

Q:  Can I use Slopegraide while playing on the golf course?

A:  Yes!  The clip attachment is designed to keep the sensor in the same position when affixed to your belt, belt buckle, or golf apparel.  However, the sensor may drift out of its calibrated position with excessive movement, such as running or jumping.

Q:  Is Slopegraide legal for use in tournament play?

A:  No.  Any electronic device that measures slope is prohibited in a stipulated round of golf.  

 

HOWEVER, if you are playing a practice round for a tournament and the pin locations are marked on the greens, you can use Slopegraide to capture slopes of interest as long as you write them down in a notebook sized no greater than 4 x 7 inches.  

 

See the USGA Frequently Asked Questions section on Green Reading Materials for more information here.

Q:  Can I use any belt buckle to mount my Slopegraide sensor?

A:  No.  There are some belt buckle designs that are NOT compatible with your Slopegraide sensor, as it will put too much stress and strain on the mounting clip.  The mounting clip will more than likely break if you attempt to mount your Slopegraide sensor on any belt buckle that does not have a flat back.  If you do not have a flat, plaque-styled belt buckle, please use the body of the belt next to your buckle to mount your Slopegraide sensor.  

 

If you have a traditional leather belt, the middle loop at the belt buckle is an acceptable position to mount your sensor.

Q:  I'm getting inaccurate readings in the Slopegraide app.  Do I need to calibrate my Slopegraide sensor again?

A:  Yes.  It is possible that your sensor was bumped or has drifted away from its calibrated position.  We strongly do not recommend running or jumping while wearing your Slopegraide sensor in order to keep it in its calibrated position.  It takes no more than three seconds to re-calibrate your sensor.

NOTE:  It is also important to keep in mind that calibrating your Slopegraide sensor is the first thing you will do before each practice session on the putting green and round of golf.  Your body posture and clothing will change from day to day, which means that the centered position of your Slopegraide sensor will change as well.

Q:  Does the Slopegraide sensor have to be positioned at the center of my midsection?

A:  For best results, we strongly recommend that you wear your Slopegraide sensor as close to the middle of your midsection as possible.  See the diagram below for further explanation.

When the sensor is worn on your midsection, a level is created with your waistline, your two legs, and the ground you are standing on.

The Slopegraide sensor represents the fulcrum.  

 

As you stand on slope on the green, your hips will naturally tilt down the slope due to the effects of gravity.  

 

If the sensor is not located in the center of your midsection, the displayed values within the Slopegraide app may be inaccurate due to the position of the sensor.  

 

In this example, if the sensor were located on the right hip, the app may be display slope values too high for putts breaking left to right and slope values too low for putts breaking right to left.

Q:  How can I use Speedgraide for uphill and downhill putts?

A:  The approximate duration to the hole displayed in the Speedgraide calculation is assuming that there aren't any uphill or downhill forces impacting the speed of the golf ball.

For uphill putts, you can estimate the amount of feet uphill to the hole and then SUBTRACT that amount from the original length of your putt to get an approximate estimate to the hole.  For example, if you are putting to a hole 2 feet uphill, you can subtract at least 2 feet from the distance of your putt to get an approximate duration to the hole.

For downhill putts, you can estimate the amount of feet downhill to the hole and then ADD that amount from the original length of your putt to get an approximate duration to the hole.  Downhill putts will take longer to get to the hole because the initial velocity of these putts are slower.
