Read the hole
before you play it.
Step to the tee like you've played the hole before. GPS previews and fly-throughs show the shape and the trouble, and plays-like distances fold in wind and elevation so the number you trust is the number that matters.
Fly through every hole Flyover
The camera glides down the fairway centerline from tee to green, so you see doglegs, elevation, and trouble before you swing.
Plays-like distance Wind + elevation
Certus adjusts the raw yardage for wind and uphill/downhill, so you know the number the shot actually plays.
Front / middle / back GPS
Live distance to the front, center, and back of every green, plus tap-anywhere targets to any hazard or layup.
Drag-to-aim with fairway snap
Drop a target down the fairway and Certus snaps it to the corridor and bends it around doglegs using real fairway shapes.
Shot logging & scorecards GHIN
Log each shot by GPS, auto-save hole by hole, and resolve the exact tee set — feeding the stats engine automatically.
Read the green before
you get there.
Every green carries a slope map — direction and severity across the whole surface, from the same survey data tour yardage books are built on.
Land it on the right tier and the putt is flat; the map shows you which tier that is, from the fairway.
Same course.
What changed?
Pick two rounds at the same course and every number sits side by side: score, putts, greens, penalties, scrambling — and strokes gained, so you see what each round actually cost.
Down to which nine did the damage, hole by hole, with a running score between the two.
Plays-like, decomposed
The adjustment isn't a fudge factor. Live wind is split into its headwind and crosswind components against your shot line, elevation change is read from terrain data for the exact target you've picked, and air density — temperature, humidity, altitude — moves the number the way it moves the ball.
Weather that updates itself
Conditions come in live and re-resolve as you play, with gusts shown alongside sustained wind. Planning a morning round the night before? Set a tee time and see the forecast wind on every hole.
See the wind, not just read it
Tap the wind card and animated streaks flow across the hole in the wind's true direction — more of them, moving faster, as it blows harder. A four-club wind should look different from a one-club wind.
Elevation on the line
Rise and fall along the fairway is marked in plays-like terms right on the hole — a +3 by a landing zone means that spot plays three yards longer. The number lives where the decision happens.
Greens with a read
A color-coded slope overlay on every green shows where it tilts and how hard, with a full-screen green view when you're planning the approach. Land on the correct side of the slope and the course gets two shots easier.
Front, middle, back — and the spot that matters
Live carry numbers to front, center, and back, plus the pin-relative read: how deep the green is where you're actually aiming, not just its longest axis.
A caddie with your numbers Caddie
The club call comes from your real yardages and your real dispersion — not a generic chart. It weighs the trouble around the target the way you'd want your caddie to, and it explains its reasoning in a sentence.
Tournament-legal mode Rules of Golf
One switch puts the GPS in a conforming, distance-only state and badges the screen so there's no question — a seal and the word LEGAL, visible at a glance to you and anyone beside you. Flip it back after the round.
Log shots as you walk
Mark each shot where you hit it and Certus measures the distances for you, saves the hole as you finish it, and hands the round to the stats engine the moment you sign the card.
The right tees, exactly
Courses resolve against the GHIN database — combined tees, state quirks and all — so slope and rating are right and your handicap math is honest.
