FAQ's

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.

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.  According to Rule 4.3 in the Rules of Golf, any electronic device that measures slope or recommends a line of play 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.

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, such as a web belt buckle.  It puts 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:  Not necessarily.  While it is possible that your sensor was bumped or has drifted away from its calibrated position due to loose clothing or a loose belt,  another possibility for this situation is that your hip line is not parallel to the slope you're standing on.  We strongly do not recommend running or jumping while wearing your Slopegraide sensor in order to keep the sensor 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 lower body.  

When you stand on slope, 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.  

For 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.
