Ross brings a focused 2009 lineup to the market with two models -- the Cardiac and Carnivore. Each is offered in multiple configurations to satisfy most any bowhunter.
The Carnivore series (offered in 31-, 34- and 37-inch axle-to-axle models) features Ross's proprietary Krank pulley system for increased limb durability and a smoother draw cycle. Other notable features include a fully machined reflex riser, machined aluminum broadhead guard, Flatline dampening accessories, near parallel limbs and a hybrid cam system with one module for all draw-length options.
Cams And Pulley
Ross achieves an ultra smooth draw cycle with a combintion of hybrid cam eccentrics and proprietary Krank pulley.
Ross designed the Carnivore's machined aluminum cams to have a large diameter and primarily circular shape. There are no drastic structural changes to translate into an aggressive draw cycle like that found on some radical speed cams. The cams ride on sealed bearings and create letoff that's adjustable between 65 and 80 percent by moving the draw stop position. Draw length can be adjusted from 26-31 inches, in half-inch increments, with a single rotating module.
Situated near the lower third of the cable system, The Krank helps provide a super smooth draw. This design also allows Ross to use a split harness on each limb, which provides superb limb strength and stability.
The Carnivore's Krank pulley is situated near the lower third of the cable system, where it is connected to both the upper and lower portions. The upper cable length is split near the top cam and is anchored to each end of the axle. The lower portion of the cable runs through the pulley with one end anchoring to each end of the bottom cam's axle and the other end anchoring directly to the cam.
The Krank's action, coupled with the cam's shape, produce the smooth draw Ross is looking for. Another Krank benefit is that it creates a 2:1 load ratio, allowing Ross to use limb sets with twice the deflection value compared to that of normal limb sets. The result is a bow with a set of super rugged and durable limbs.
In testing, the Carnivore 34 had one of the smoothest draw cycles I have tested to date. A gradual incline to peak was followed by a gentle rollover to a declining plateau. Where most bows seek to hold the plateau at a constant, Ross designed the Carnivore so that draw weight will decrease slightly at the top. A slight decline will obviously have a smoother feel as compared to a draw cycle that holds a constant plateau weight. Further, the back end of the cycle has a large radius before easing into full draw letoff.
Ross knows its customers want a silent rig to carry into the woods in pursuit of wary game, and to that end, they have outfitted the Carnivore with multiple noise and vibration dampening features and accessories. Each limb has a factory-installed Flatline vibration dampener attached on its underside. The limbs themselves add a measure of silence with their near parallel position. Limbs with a parallel or near parallel position reduce shock and vibration by moving in opposite directions at the shot, effectively cancelling out much of the energy that is left over after propelling the arrow. A single, double-flanged
Flatline dampener is affixed to the cable guard in front of the Teflon cable guard slide, and two more Flatline dampeners are placed in the string near each cam. A final silencing feature is found in the string suppressor tipped with another Flatline dampener.
The string suppressor is attached in the rear stabilizer-mounting hole.
Riser And More
Ross CNC machines their reflex geometry riser from a 6061-T6 aluminum extrusion. The Carnivore 34 is built like a tank, with a solid riser and mass weight of 4.8 pounds. This stout design offers terrific balance and stability at full draw. I found the Carnivore well balanced and steady on target. Other riser features include a one-piece plastic grip, machined aluminum broadhead guard and stainless steel stabilizer mounting insert. The riser and limbs are finished in Realtree APG camo and protected with InVelvet, a rubberlike wear- and chemical-resistant coating. Limb pockets and eccentrics are anodized in a pewter color.
Editor's Note: Our standardized High Grade testing includes the use of the same equipment and test methods. All bows are tested with a draw length of 29 inches and a draw weight of 65 pounds. Speed tests are conducted with two different arrow weights -- 375 grains and 425 grains.
