Alloy Golf Ball Marker with Slope Reader

Each marker measures 4.4 x 2 cm and is made from lightweight yet durable space-grade aluminum alloy. Weighing only a few grams, the set includes 2 identical markers — compact enough to clip onto a golf hat or serve as a functional ball marker on the green. Designed for immediate slope assessment, the built-in precision level allows visual reading of green tilt directly behind the ball. Works reliably on all green surfaces — bentgrass, poa annua, artificial turf — without calibration or batteries. Ideal for amateur and club-level players seeking consistent, repeatable green-reading support during practice or play.
