Compound bow for adults Poe Lang Cobra Protex 2.0 55 lb 40.2" black

Cobra Protex Compound Bow in black belongs to the recreational bow category with high draw weight. Its sturdy construction, consisting of a metal riser and fiberglass limbs, makes the bow aesthetically pleasing and comfortable to use.

The cables that synchronize limb movement are made of steel wire with a protective coating to prevent abrasion. The string is made from specialized fibers. The Cobra Protex features threads for mounting an arrow rest, sight, and central stabilizer. The ergonomically shaped grip is made from comfortable, anti-slip material.

The compound bow propels arrows using energy stored in the limbs and transmitted by the archer’s muscles. A distinguishing feature of compound bows is the distribution of peak draw force: the maximum draw weight is reached at approximately half draw length. Beyond this point, let-off occurs, allowing the archer to hold the string using only 30–50% of the peak force. This is achieved through cams and wheels rotating eccentrically around their axes.

For fast or short compound bows, a release aid should be used (D-loop required on the string). Finger shooting may cause the string to slip off the cams, potentially damaging the bow. Compound bows for children, youth, and longer recreational models are designed for both finger shooting and release aid use.

Archery technical specifications are expressed in the imperial system:

• Length: inches (in), 1" = 2.54 cm;
• Weight: pounds (lb/lbs), 1 lb = 0.45 kg;
• Speed: feet per second (fps), 1 fps = 0.3 m/s ≈ 1.1 km/h.

Each advanced compound bow requires proper mounting and adjustment of accessories:

• arrow rest;
• sight;
• peepsight;
• release aid;
• D-loop for release aid shooting.

Each element must be properly set to achieve maximum performance.

How to read technical data

• ATA (axle-to-axle) length: distance between the centers of cams on opposite limbs.
• Brace height: distance from the deepest point of the riser grip to the string at rest or from arrow rest mount to string.
• Draw length: distance from the arrow nock to the bow back when drawn.
• Draw weight: force required to fully draw the bow, typically adjusted via limb screws.
• Maximum arrow speed: achieved at maximum draw weight.
• Weight without accessories: bow weight without additional equipment.
• Let-off: the percentage reduction in force needed to hold the string past peak draw weight (e.g., 65% reduces the holding force by 65%).
