We simulate 1,000 shots with your handicap and club distances against the real hazard layout of your course. The result: the right club, the right target, and a plan you can print and take to the tee.
You're standing on a 380-yard par 4 with water left. Driver or 5-iron?
A 15-handicap hitting driver puts the ball in play 52% of the time. The same golfer with a 5-iron? 83%. The longer approach costs half a stroke — but the saved penalty strokes more than compensate. The 5-iron scores better. Most golfers would never know that without the data.
Yards Golf Book runs this analysis on every hole of your course — 1,000 simulated shots with your specific handicap and club distances, checked against every bunker, water hazard, tree line, and OB stake. The result is the club and target that actually minimize your score, not the one that feels right.
Handicap index and club distances. That's all we need. Your dispersion model is calibrated from USGA research data for your skill level.
Over 100 courses fully mapped with shot dispersion and strokes gained strategy. 12,000+ more across North America being added — with GPS hole layouts, hazard positions, and elevation data sourced from OpenStreetMap and satellite imagery.
For every hole: the optimal club, the best aim point, and the expected outcome. Download your game plan as a PDF and play phone-free.
Every recommendation is backed by simulation, not heuristics.
For every candidate aim point, we simulate 1,000 shots using your handicap-calibrated dispersion pattern. Each shot lands on the hex grid, gets evaluated for strokes gained, and the average determines the recommendation.
Every position on the hole color-coded by expected strokes to hole out. Green means you're gaining on the field. Red means you're giving strokes back. The optimal target isn't always the fairway center.
A 150-yard shot playing 30 feet uphill isn't a 150-yard club. The model adjusts effective carry distance using elevation profiles extracted from GPS routing data. 0.55 yards per foot uphill, 0.45 per foot down.
"Better to miss long than come up short." The strategy text explains the recommendation in plain English — which side to favor, what the miss costs, and when to take on risk vs. play conservative.
100+ courses fully mapped with complete strategy tools. 12,000+ more across North America being added — hole boundaries, fairway polygons, bunker positions, water hazards, tree canopies, and green contours extracted from OpenStreetMap data and satellite imagery. New courses go live every week.
