What They Have in Common
Both are Tier 4 rangefinders targeting the same buyer at roughly the same performance level. You get 6x magnification, ±1-yard accuracy, slope mode, and pin-lock vibration on either one. They'll both read out to 1,000+ yards, which is more than you'll ever use on an actual course. The fundamentals are covered by both.
Where They Differ
Battery Life and Reliability
This is where the GolfBuddy earns its keep. The 2S PRO runs on a CR2 3V lithium battery rated for 5,000+ actuations — that's a meaningful spec. CR2 batteries are at every pharmacy in the country, which matters when you're mid-round and realize the thing is dying. You swap it in 30 seconds and you're back. Voice Caddie doesn't publish a battery spec for the L6 at all, which isn't necessarily a red flag, but it's not nothing either. When a manufacturer doesn't include it, you don't know what you're getting.
Display and Low-Light Performance
The L6 wins here, clearly. OLED displays pop in a way standard LCD or LED screens just don't — better contrast, sharper readout, easier to pick up at a glance. GolfBuddy doesn't publish what display type the 2S PRO uses, which probably means it's not OLED. Seems like if it were, they'd say so. If you're playing early morning rounds or late-day twilight golf where the light gets flat, OLED is a genuine advantage. In direct sunlight the gap narrows, but in tricky light it's real.
Water Resistance
The Voice Caddie L6 is listed as water-resistant. The GolfBuddy 2S PRO has no water resistance rating published. That's a notable gap. A $200 rangefinder that survives a surprise shower is a better long-term bet than a $150 one that might not. If you play in the Pacific Northwest, Scotland, or basically anywhere with real weather, this probably tips the scale more than the price difference.
Extra Features on the GolfBuddy
The 2S PRO brings a few things the L6 doesn't: a triangulation feature, Buddy Mode (which gives distance ranges to the front and back of the green, not just the pin), and a magnetic cart mount that actually holds it while you drive. Buddy Mode is quietly useful when you're between clubs and want the full picture, not just the pin. The magnet mount is one of those things you don't think about until you have it, and then you miss it on every other rangefinder.
Who Should Buy Which
Get the GolfBuddy GB LASER 2S PRO if:
- You play fair-weather golf and weather resistance isn't a factor in your purchase decision
- You want a magnetic mount so the rangefinder stays on the cart without clipping and unclipping it every hole
- You care about knowing the battery spec up front — 5,000 actuations gives you a real number to work with
- You're the player who wants Buddy Mode's front-to-back distances when you're between a 7 and an 8 into a narrow green
Get the Voice Caddie L6 if:
- You tee off at 7am in October when it's still wet and you've had a rangefinder fog up or die on you before
- You want the OLED display — it's not a gimmick at this price, it's the sharpest readout you'll find in the tier
- You play enough rounds in variable weather that "water-resistant" is a purchase requirement, not a nice-to-have
- You'd rather pay $50 more now than worry about what happens the first time it catches rain
The Bottom Line
These two are competing directly at the same tier and same performance level, with a $50 gap and a handful of real trade-offs. The GolfBuddy 2S PRO gives you more features per dollar — magnetic mount, Buddy Mode, a clear battery spec — and at $149.99 it's the easier call for most buyers. The L6 answers back with OLED and water resistance, and those aren't nothing, especially if you play in wet conditions regularly.
I'd go with the GolfBuddy. The magnetic mount and known battery life are things you'll use every round. The extra $50 is a sleeve of balls.
