Knowing your exact distances is one of the fastest ways to improve course management and lower your scores. But with GPS watches, handheld GPS units, and laser rangefinders all competing for your wrist and bag, which technology is actually best for your game?
GPS Watch: The Convenient All-Rounder
Modern GPS watches like the Garmin Approach S70 and Bushnell ION Elite offer hazard distances, shot tracking, and green mapping all from your wrist. They're hands-free, work instantly, and the best models include front/middle/back distances plus hazard yardages to bunkers and water.
Pros
- Hands-free — no fumbling in your bag or pocket
- Always on, shows distances as you walk
- Shot tracking and statistics on premium models
- Works in any weather — no line-of-sight required
- Subscription free on many models
Cons
- Screen can be hard to read in bright sunlight
- Only shows pre-programmed targets, not arbitrary targets
- Battery life can be an issue on 18+ hole rounds
- Course maps not always updated for newer layouts
Laser Rangefinder: The Precision Instrument
Laser rangefinders like the Bushnell Pro X3+ and Nikon Coolshot Pro II Stabilized give you pinpoint accuracy to any target you can see — the flag, a bunker face, a tree, or any landmark. Tournament-legal models are used by professional caddies worldwide.
Pros
- Most accurate technology — within 1 yard of any visible target
- Works on any course without pre-loading maps
- Slope mode shows plays-like yardage for uphill/downhill shots
- Premium models have stabilization for ease of flagging
- Long battery life (months on a single battery)
Cons
- Requires taking device out each shot
- Can't show hazard distances or distance behind pin
- Foggy or wet conditions can affect accuracy
- Not hands-free — requires one hand and focusing effort
Best of both worlds: Many serious golfers use a GPS watch for hole overview and hazard awareness, then pull out the rangefinder for precise flag distance on approach shots. This combination adds under $30/month amortized over 4 years.
