What Our Gearhead(R) Experts Are Saying:"The Ultralight Master Cam has become my go-to for filling the gaps in a mixed rack - the size range is wide enough to cover cracks that other cams miss, and the Range Finder dots make it fast to confirm a solid placement without second-guessing. The trigger action is smooth and confidence-inspiring, and at these weights I barely notice them on long alpine routes where every ounce starts to add up."A well-built rack is more than a collection of cams - it's a system, and the gaps in that system are where the Metolius Ultralight Master Cam earns its place. CNC-machined to be 40% lighter than the original Master Cam, this is the cam that disappears on the harness until the crack demands exactly what it's sized for, then delivers a solid, confidence-inspiring placement without hesitation. The four-lobe design with a single axle and single stem keeps the profile clean and the action smooth, and the Range Finder dots along the lobe sides take the guesswork out of marginal placements - green means go, red means find a better spot. Color-coded triggers, thumbs, and webbing make size identification fast on the wall, and the replaceable UHMWPE Monster Sling keeps the overall weight honest across ten sizes from fingertip-thin 00s down to fist-width 8s. For trad climbers building a primary rack or alpine climbers who can't afford extra grams on a long objective, the Ultralight Master Cam is a serious piece at a price that doesn't require a second mortgage.
