Why Serious Golfers Trust the SightLine

SightLock™: Know You've Got the Right Pin
Most rangefinders leave you wondering — did it lock the flag, or a tree behind it? SightLine's SightLock™ system sends a physical vibration the moment it confirms the pin. No second-guessing. No re-measuring. Just a buzz in your hand and the confidence to pull the right club.
Slope Tech That Thinks Like a Caddie
A 160-yard shot downhill plays like 148. Most golfers either ignore that — or pay $400 for a rangefinder that accounts for it. SightLine's Adaptive Slope™ mode calculates the true play distance based on elevation in real time. One tap of the external switch turns it off for tournament-legal play. Same device. Every situation.
Built for the Course. Ready for Anything.
IP54 waterproofing. Magnetic strip that snaps to your cart in a second. A 1,050mAh battery that powers 40,000 measurements on a single USB-C charge. 7× magnification that locks onto flags at 400 yards like they're standing next to you. The SightLine was engineered for real rounds in real conditions — not just a product shelf.

Frequently Asked Questions

Is the SightLine legal for tournament play?

Yes — completely. The external slope switch physically disables slope compensation data, making the SightLine fully USGA tournament-compliant. Flip it off before your round and you're ready for competition. Flip it back on for practice and casual rounds.

How accurate is it, really?

The SightLine measures from 3 to 1,200 yards with ±0.5 yard accuracy. For comparison, that's tighter than most rangefinders at double the price. The SightLock™ vibration system also confirms you've targeted the flag — not a tree or cart behind it — so your reading is always the right reading.

What does "slope-adjusted yardage" actually mean?

When you're hitting uphill, the ball needs more distance to carry — and downhill, less. Slope mode calculates the adjusted "play yardage" based on the actual elevation change, not just straight-line distance. So if you're 160 yards out but playing 8° downhill, SightLine tells you to play it like 147. Fewer wasted strokes from misjudging terrain.

Does it need batteries? How long does it last?

No disposable batteries needed. The built-in 1,050mAh lithium battery charges via USB-C in 1.5–2 hours and powers approximately 40,000 measurements — enough for over 200 full rounds before needing a recharge. The device auto-powers off after 30 seconds of inactivity to preserve battery life.

Will it hold up in rain or damp conditions?

Yes. The SightLine carries an IP54 waterproof rating, meaning it's protected against splashing water from any direction and resistant to dust. Whether you're playing through early morning dew, a light drizzle, or a surprise shower, your rangefinder keeps working.

What's included in the box?

Your SightLine set includes: the rangefinder unit, a protective carry case, a hand strap, carabiner clip, USB-C charging cable, lens cleaning cloth, and user manual. Everything you need to start measuring accurately from round one.
