i4 Features and Benefits

Real-Time FS Environmental Optimiser Engine
Precise effective playing distance calculations for every club using FlightScope Environmental Optimiser, ensuring accurate information for every shot under varying environmental conditions.
One of the standout features of the FlightScope i4 is the powerful Environmental Optimiser engine. The EO pulls real-time weather data, including air density and kinematic viscosity, ensuring that its distance calculations are always accurate and relevant to the current playing conditions. The FlightScope i4 apart from traditional rangefinders, making it a must-have for any golfer who wants to improve and score better.
Effective Playing Distance
Provides a dynamic effective distance that uses your home location as a reference and then based on real-time local environmental conditions such as local air density, kinematic viscosity, and the target's elevation.
Use the i4 Rangefinder to ensure you have the most accurate distance calculations, to help improve shot precision and performance in any condition.


Personalised Club Recommendations
Never pull the wrong club again! The i4's club recommendations are based on your personal launch data, current weather and environmental conditions, including wind speed and direction, ensuring that every recommendation is tailored to your ball trajectories in the current environment.
i4 AI Smart Gapping
Don't have a launch monitor? Use the i4 Smart Gapping tool to get a personalised club gapping report that can be used for your personalised club recommendations.
With the FlightScope Smart Gapping AI tool you can give us one of your carry distances (or more if you choose) and get an instant report with carry distance, ball speed, launch angle, and spin values for every club in your bag. Generate your report with just a few inputs:
Home Location: Adjusted for height above sea level.
Carry Distance: Entered for one or more clubs at the Home Location.
From these inputs, the Smart Gapping tool calculates the carry distance for each club, along with nominal ball speeds, launch angles, and spin values. This tool ensures that every golfer, regardless of their experience level, has access to accurate and personalised distance information.


Wind Speed and Direction
Simple user-selectable wind direction paired with real-time wind speeds from local weather stations to help calculate effective playing distance and give you the best, most accurate yardage possible.
Slope Compensation
Adjusts the distance to a target by accounting for the slope of the terrain using effective distance calculation.


Built-in Magnet
For ease of use and easy accessibility in golf carts.
