Best Launch Monitor for a Home Simulator: R50 vs Mevo Gen 2 vs GC3S

When someone asks me for the best launch monitor for a home simulator, my first answer is always a question: how much room have you got behind the ball? Because in 2026 the UK market has settled into three genuinely excellent options at three price points, the FlightScope Mevo Gen 2 at £1,199, the Foresight GC3S at £3,990 and the Garmin R50 at £4,299, and the right one for you is decided less by spec-sheet bravado than by your room dimensions, your software plans and whether you want a computer in your life. I sell and support all three, so this comparison has no horse in the race beyond you not messaging me in six months to swap one. The fundamental split: radar behind you, cameras in front The Mevo Gen 2 is radar. It sits about 2.4m behind the ball, watches the flight and computes your numbers from what it tracks. FlightScope has been building radar for professional golf for decades, and the Gen 2 is that pedigree at a consumer price. Radar’s strength is tracking real flight, which makes it superb outdoors; its cost is space, because the unit-behind-ball requirement adds ~2.4m to your room length, and that is precisely the length many UK garages do not have. The GC3S and R50 are photometric: cameras photographing the ball at impact from in front of or beside it. The Foresight GC3S sits roughly 60cm in front of the ball; the R50 uses a triple camera array from a floor position in front of the ball too. Cameras measure launch directly rather than modelling from flight, which is exactly the advantage you want indoors, where the ball flies three metres into a screen and radar has the least to work with. Cameras also shrink the room requirement, which for a lot of readers quietly ends the comparison before the data debate starts. What each one is actually like to live with FlightScope Mevo Gen 2, £1,199 The value pick, and not grudgingly: the Mevo Gen 2 produces simulator-credible data at less than a third of the price of the other two, and it is the unit I recommend most often to golfers building their first proper sim on a sensible budget. It wants its space behind the ball, it wants decent alignment, and as a single-sided radar it needs repositioning when a left-hander steps in, so mixed-handedness households should think twice. One FlightScope-specific warning I give every buyer: the simulation software is non-refundable once activated, so choose your software package deliberately before you activate anything. As a complete room, the Mevo Gen 2 Full…
