Rangefinders are being seen in use on the course more and more. The two
main types arelaser
rangefinder and GPS. But which one is better for
you? There are both advantages and disadvantages for both types.
Let’s start with the laser rangefinder. This works by picking a target which the
laser sends a beam of light to and measures the time it takes to bounce back.
Laser Rangefinder – Advantages
• Very accurate ( to within 1 yard)
• Can get a distance to any target on any golf course
• One off cost
• No downloads required
• Light and durable
• Some give slope readings as well for greater accuracy
Laser Rangefinder – Disadvantages
• If you can’t see the pin you cannot get a distance
• Must keep it steady to home in on pins
• Can have heavy battery use
• Bad weather can make it difficult to use
GPS works by downloading a map of the course onto the unit. When you are at the
course the unit locks into a local satellite and you are set to go.
GPS – Advantages • No picking and shooting at targets, just look at the screen
• Screen shows hazards etc.
• Very easy to use
GPS – Disadvantages
• Can be a large error variation +/- 3 yards
• You have to estimate where the pin is on the green
• Not flexible will only give distance to mapped points
• Can’t use it at most driving ranges
• Not all courses are properly mapped
• Can take time to lock onto satellite
• Annual fee
• Can have heavy battery use
• Bad weather can play havoc with GPS
I believe it comes down to you having to weigh up ease of use against accuracy to
decide which type is best for your game.
One thing to point out is rangefinders that have built in slope measuring are illegal
to use in any tournament. For use of normal laser rangefinders and GPS in tournaments you must check with the
tournament organizer to see if they are allowed. If you use one when they are not allowed it is automatic
disqualification for you.
