Construction / Design

It’s hard to describe the construction of this golf rangefinder until you have it in your hands. Very ergonomic design. Buttons are in the best places possible making the device very easy to operate.

Measurement Modes

There are six modes of measurements:

  1. Standard – a basic mode which is recommended when measuring distances to larger objects
  2. Pin Acquisition Technology – a great choice when measuring distances to smaller objects (i.e flagsticks)
  3. Birdie Technology – a sound alarm will be heard when the device is locked onto the pin
  4. Slope Mode – measures the angle of a slope. Extremely helpful to calculate the slope adjusted distance
  5. Scanning – measures distances between multiple objects
  6. Unit of Measure – you can switch between yards and meters when using the device

Ease of Use

You can measure distances with only one hand which is super handy. The interface is as easy as it can get, even beginners shouldn’t have any problems using it.
