Foresight Sports (Bushnell Golf family for many retail paths) is the photometric standard in fitting bays: floor units like GCQuad and GC3 sit beside the ball and read impact with camera-based precision fitters trust for spin and club data.
For home sims, the appeal is accuracy plus FSX / FSX Play software without needing radar depth behind the golfer. Side clearance and unit protection matter - mishits love expensive floor boxes - but many mid-depth rooms that cannot fit radar still fit a GC-style bay.
Compare models on club-data needs: higher tiers earn their keep for fitters and serious practice; lighter models can be enough for entertainment-first rooms. Confirm software subscriptions and whether you also want GSPro or another connector later.
Best when photometric fitting-grade data and a mature FSX path matter more than brand tourism. True portable outdoor-only buyers, or anyone who refuses floor clutter beside the ball, usually look at other form factors.
