Diamond Core Bow Review
December 02, 2013
Diamond Archery's new Core is a versatile, ready-to-shoot rig that hits the sweet spot between value and performance. With loads of features, included accessories and a $499 price, you simply cannot go wrong. The Core is outfitted with a set of E-Glass composite limbs, Core Single Cam with rotating module, String Stop, one-piece synthetic grip, super adjustable limb-containment system and a full R.A.K. (Ready. Aim. Kill.) accessory package.
Mad Max Money
Your mad money stash will be well spent if you walk out of your local pro shop with the Core. Not only is the price tag attractive, but you save big on accessories thanks to the R.A.K. package, which includes an Octane Capture arrow rest, 3-pin Apex sight, Octane DeadLock Lite quiver, braided wrist sling, 5-inch Octane Ultra-Lite stabilizer, alloy peep sight and BCY string loop. This Core is ready to shoot right out of the box — just add arrows.
As a safety note, make sure you use arrows that are properly spined for your chosen draw length and draw weight. If you adjust either of these out of the range of your chosen arrows, you should consult a pro shop or manufacturer's spine chart and purchase new arrows if necessary.
Diamond's Core is made to fit a wide range of shooters with draw lengths and weights that cover a lot of ground. The Core Single Cam system and idler wheel are machined of aluminum and ride on bearings to reduce friction and increase efficiency. The open design of the cam and idler uses minimal material and is complimentary to the overall light mass weight of this rig — a feathery 3.2 pounds!
A rotating module on the cam allows you to easily adjust across the entire draw-length range of 25-30 inches, in half-inch increments, without a bow press. Index marks on the module and cam offer positive positioning and also correlate to the adjustable draw-stop hole. Both cam and idler are designed with deep grooves to enhance reliability (no rolling the string off the cam or idler). System letoff is advertised at 80 percent.
The Core also features a generous draw-weight range of 40-70 pounds at all draw lengths. The riser is designed to accept a super long limb bolt, and each full turn of the bolt is equal to approximately three pounds of draw-weight adjustment. A limb-bolt inspection hole is designed right into the riser so you can keep an eye on the bolt positioning.
The bolt must not be backed out past this window for shooting — it must be visible in the hole. Additionally, both top and bottom limb bolts should be adjusted equally so each limb is in the same position relative to the riser. Limb-bolt adjustment marks on the shaft of the bolt become visible as the end of the limb separates from the riser.
Limbs are made of E-Glass composite material and are machined into their final form before being matched based on deflection values. The limb-containment system is very light on material and partially integrated into the riser. A small, cap-like fixture aligns the bolt to the limb and two tabs built into the riser keeps the limbs aligned to the riser.
The Rest of the Story
Diamond outfits the Core with a reflexed aluminum riser that serves as the base for several features, including the integrated limb pocket mentioned above. Also attached to the riser's handle is a one-piece synthetic grip designed to encourage a neutral wrist position. A broadhead guard is molded directly into the grip as well. A string stop mounted opposite the stabilizer mounting hole couples with the cable silencers to reduce shot noise.
At just 3.2 pounds and 31 inches between the axles, the Core is super maneuverable. And the draw cycle is super smooth. The Core's grip is comfortable and functional. Shot noise was minimal, though there was notable vibration and hand shock.
Keeping in mind the Core's price tag, it is a very good value setup!
