Spring into Solved Errant Golf Ball Problems

Avoid potential damage that can be caused by errant golf balls. Take constructive action in resolving safety issues that could cost your club $$thousands.

Currently, to enable golf courses and driving ranges to "spring into action," we offer a special service for a cost of only $299:

1. We'll analyze up to 3 holes on your golf course for potential errant golf ball problems.

2. For each hole, we'll clearly describe the potential problem(s) and offer some possible solutions.

3. All you need to provide is a copy of your golf course scorecard with schematic course layout along with the address of the golf course.

4. Google Earth will be utilized to survey the golf holes in question.

5. You'll have the opportunity to describe any issues you've identified (if you choose) before we conduct our analysis.

Feel free to email if you have any questions. You'll then be sent a secure link for payment of the $299 fee.

Otherwise, click on the pay link below to submit your payment. You'll then be sent a request for a diagram of the golf course layout. Usually, your analysis will be completed within 3 days.

Errant Golf Ball Analysis

I have consulted on over 30 cases involving errant golf balls. All of the cases can be categorized into 3 distinct groups:

1. Pre-Incident

A change is proposed to an existing golf course or driving range in which the parties involved want to avoid any errant golf ball issues after the change in made. I work with the golf property and the adjoining property owner to ensure the likelihood of errant golf ball issues is minimized.

2. Post-Incident

An errant golf ball problem has already been identified and a solution is desired by either one or both parties involved. Sometimes this involves lawyers if one party is not happy with the progress.

3. Post Accident

An errant golf ball (or balls) has caused damage to person or property. Lawyers are involved and likely litigation. In many cases, the potential of the incident had been identified by at least one of the parties.

If there is an errant golf ball issue, how does one determine the theoretical severity of the problem along with the recommended solutions?

1. Site Analysis

Firstly, a site analysis is performed, most of which can be done using Google Earth data. Distances and angles are measured along with any elevation changes (topography). Prevailing wind and temperature data is researched.

2. Golf Ball Trajectory Software

Software is utilized to simulate errant golf ball trajectories. This software predicts trajectories in very close agreement to the trajectories measured by the Trackman and Flightscope Radar Golf Monitors. The simulations can determine the lateral distances (left and right) as well as golf ball height at any distance with inputs of golf club speed, loft, backspin, etc.

3. Real golf ball data by a full range of golfers is used to produce scatter plots shots off the tee and/or for any club and distance. A large portion of the shots is found to end within a "cone of scatter" of a certain angle. Better golfers tend to hit their shots within a narrower cone.

Using this data, one can calculate the percentage of golfers that will likely hit outside the cone and thus become a dangerous, errant golf ball that might land onto an adjacent property. The Golf Ball Trajectory Software can then determine the golf balls' heights and thus the required heights of netting to contain such shots.

One can calculate a containment percentage based on the height of the netting. Different heights would contain different percentages of shots.


25 yd height contains 90% of shots
30 yd height contains 95% of shots
35 yd height contains 98% of shots

See sample images below showing the scatter of Tees Shots and the scatter of iron shots to a green.
