PSE Mach 33 DS - FDS Cam

Our take:

The PSE MACH 33 DS with the new FDS cams offers more stability at full draw by increasing the effective brace height (distance between the throat of the grip and where the string comes off the cam at full draw). In short it feels more like a 7" brace height bow while maintaining or even increasing the speed slightly over the EC2 cams. You can change the let off from 85% down to 70% so it's easy to find the feel you desire at full draw. 

From the manufacturer:

Named Outdoor Life’s 2025 Bow of the Year, the Mach 33 DS stretches out to a true 33 inches axle-to-axle, delivering the comfort of a perfect string angle and the steadiness of a longer platform—without the bulk. This is the bow built for hunters who want it all: speed, forgiveness, and silence in one carbon package.

The FDS Cam System drives performance with a silky draw, a back wall that won’t budge, and 10 extra FPS for flatter arrows that punch harder. Up to ⅞-inch more effective brace height gives you breathing room on high-pressure shots, while oversized ⅝-inch cam bearings provide bulletproof smoothness in harsh conditions.

The Dead Frequency Carbon riser makes every shot whisper-quiet and dead in the hand, while Full Draw Stability keeps you locked on target. With adjustable let-off from 70 to 85 percent and integrated mounting systems for a streamlined setup, the Mach 33 DS inspires confidence from the first light of the hunt to the final moment of truth.
