Milessey GAN Pro G1 — Touchscreen Golf Rangefinder With GPS, Slope, and Smart Layup Tools

Golf tech is changing fast, and the Milessey GAN Pro G1 is one of the most advanced rangefinders you can bring onto the course today. It combines a full touchscreen, onboard GPS mapping, slope adjustment, pin-lock technology, three-point distance measurement, and shot-tracking into one device. You don’t need a phone, smartwatch, or app open while you play — everything loads directly on the unit.

Design, Build & Touchscreen Interface

The GAN Pro G1 feels solid and premium in the hand, built with a rugged exterior designed for outdoor use. The huge touchscreen on the side is the standout feature — it shows a visual map of the hole you’re playing, your exact position, and pin placement. It also switches between GPS view and laser view depending on how you’re using it.

The USB-C port is sealed for water resistance, and the included hard-shell case makes transportation simple. It clips onto your golf bag using the built-in carabiner, so you always know where it is.

Tracking Distances & Slope-Adjusted Yardage

Using the device’s laser mode, you simply point at the target and get instant readings. On the driving range, you can lock onto pins easily — even at long distances. Out on the course, slope adjustment becomes a major advantage. The G1 shows the raw distance (for causal play) and the slope-corrected distance (for more accurate club selection). Slope can be turned off for tournament compliance.

Even on longer holes, where the pin might barely be visible, the G1 reliably locks on and gives consistent readings.

GPS Mapping, Hole Recognition & On-Course Navigation

One of the biggest benefits is that the G1 automatically recognizes the course and updates as you move from hole to hole. The GPS layout gives a visual of the entire hole, including fairway, bunkers, hazards, and green shape.

You can tap the touchscreen to measure layup distances — perfect when playing unfamiliar courses or dogleg holes where the pin isn’t directly visible. Simply tap a spot on the fairway and the G1 shows how far that layup is, plus how much yardage remains for your second shot.

For shots where the flag is out of view, the “Pin Pointer” mode gives the direction and distance to the pin, almost like being able to see around the corner.

Three-Point Measurement for Cart-Path-Only Rounds

If you’re playing a cart-path-only course, this feature is gold.

Instead of walking all the way to your ball to check distance:

1. Measure from the cart to the ball
2. Measure from the ball to the pin
3. The G1 calculates the actual yardage you’ll face

This helps you pick the right club before you even leave the cart.

Real Gameplay Experience

During real shots on the fairway, the device made it much easier to choose the right club. The slope-adjusted readings felt accurate, giving extra confidence when hitting into elevated greens or downslopes.

The GPS interface also highlights exact pin placement — front, middle, or back — which is something you’d normally need a dedicated golf watch or app for.

The G1 turned out to be extremely useful during approach shots, layups, and even tee shots on holes with blind corners. Features like these help avoid wasted strokes by improving decision-making.

Battery Life & Ease of Use

The GAN Pro G1 has excellent battery life. You can leave it on your bag for multiple rounds without thinking about charging. The controls are straightforward:

– Center button for key functions
– Touchscreen for map interaction
– Laser trigger for pin locking

You don’t need to pull your phone out at any point — everything happens on the device.

Final Verdict

The Milessey GAN Pro G1 is one of the most feature-packed rangefinders available today. It blends laser accuracy with GPS intelligence, slope calculations, layup planning, and touchscreen convenience in a way that replaces both a traditional rangefinder and a golf watch.

If you want something that gives maximum information, reduces guesswork, and speeds up club selection, this device fits perfectly into a modern golf bag. It’s an all-in-one tool that helps you plan smarter shots, save strokes, and navigate any course with confidence.
