PSE Carbon Air Mach 33 (2022): Carbon Hunting Platform With the Extra Three Inches

Three inches of axle-to-axle changes the geometry of a compound bow in ways that matter more at longer draw lengths. Shooters pulling 29" or 30" notice the difference in string angle at full draw — the angle at the D-loop is shallower on a 33" bow than a 30", which translates directly to less vertical nock travel and a more forgiving release. PSE built the 2022 Carbon Air Mach 33 specifically for that use case, giving the carbon hunting platform enough length to serve the longer-draw hunter without abandoning the weight advantages of the carbon riser.

What's notable

The Mach 33 carries the same carbon monocoque riser construction as the Mach 30, using PSE's proprietary layup system designed to control flex at the limb pockets while damping the high-frequency vibration that stiff carbon structures would otherwise transmit efficiently to the grip. The additional three inches of axle-to-axle comes from a slightly extended riser section — the limb angles and cam geometry are otherwise nearly identical between the two models. That consistency means shooters who have handled the Mach 30 will find the Mach 33 immediately recognizable, with the key differences appearing at full draw rather than at rest.

At 33" ATA, the resulting string angle at a 29" draw length is noticeably shallower than on the 30" model. That shallower angle reduces the vertical component of nock travel at release — the nock doesn't deflect as far up and down during the power stroke, which means any timing imperfection in the release has a smaller effect on arrow departure. For hunters shooting with fingers rather than a release aid, this difference is even more significant, but even with a wrist strap release, the geometry improvement is real under cold-weather shooting conditions when gloves and stiff hands make consistent release execution harder to maintain. Over a full day in the field at temperatures below freezing, the forgiveness advantage of three extra inches of ATA compounds into tighter groups.

The E3 single cam carries over from the Mach 30, with the same rotating module draw length adjustment and clearly defined back wall. Weight climbs slightly over the 30" — the longer riser adds a few ounces — but the assembled package still lands under 4.5 lbs before accessories. That remains a significant weight advantage over aluminum-framed competitors in the same performance class. The Mach 33 sits in a sweet spot: compact enough for treestand use, long enough to handle 29"+ draw lengths without geometry penalties, and light enough to carry all day without fatigue.

Who it's for

The Mach 33 is built for hunters drawing 28.5" and longer who want a carbon platform. It's also the better choice for hunters who shoot from open stands or ground blinds where axle length isn't the primary constraint, and who prioritize shot forgiveness over absolute minimum size. Taller shooters and those with longer arms who have been told their draw length is 29" or longer will get noticeably better results from the 33" than the 30" — the geometry advantage isn't subtle at those draw lengths.

New shooters and those still building toward their final draw length should consider the 33" regardless of current draw length measurement. A developing archer typically grows into more draw length over time as flexibility and strength improve, and the forgiving geometry of the longer bow accommodates that growth better than the 30".

Where it sits in the lineup

The Mach 33 was PSE's premium carbon hunting offering in 2022, positioned above the EVO XF aluminum line. It competes directly with Hoyt's Carbon RX-5 Ultra and Mathews' flagship from the same year. The Mach 30 remains the choice for compact-first hunters; the 33 is right for shooters who want carbon weight savings without the draw length penalty of a short ATA bow. Both have been succeeded by later PSE carbon hunting platforms, making second-market availability reasonable for buyers who want the platform without flagship-year pricing.

Arrow selection on the Mach 33 follows the same logic as the Mach 30: the stiff carbon riser doesn't mask spine mismatches the way an aluminum riser's natural flex does, so matching arrow spine to draw weight and length is more consequential than on some platforms. Shooters who paper-tune carefully will find the Mach 33 rewards the effort with exceptional group consistency.

The carbon riser also provides a secondary benefit that hunters who have used it for multiple seasons mention consistently: it maintains dimensional stability through temperature extremes better than aluminum, which expands and contracts measurably between cold morning stands and warm afternoon conditions. On a meticulously tuned hunting setup, thermal expansion in an aluminum riser can shift broadhead flight slightly between temperature extremes. Carbon risers don't eliminate the effect entirely, but they reduce it enough to be meaningful for hunters who set up their bows in controlled conditions and need them to perform the same way in the field.
