Tech Talk

Diamond Archery began its journey toward mainstream notoriety in the mid-1990s and has since been acquired by industry giant, Bowtech, under which Diamond continues to operate today.

The Edge 320, much like the Infinite Edge Pro, is one of Diamond Archery’s flagship models, which has directly descended from the company’s immensely popular Edge platform.

True to its heritage within the ultra-adjustable Edge series line-up, the Diamond Edge 320 features an effective draw weight range of 7-70 pounds, and a variable draw length of 15”-31”.

This range of adjustability offers immense value to archers of all ages, sizes, and experience levels.

One feature that sets the Edge 320 apart from other models within the Diamond lineup is its blazing fast IBO speed.

With the Edge 320 speeds of up to 320 FPS are possible. That is pretty impressive and more than enough.

Review of the Diamond Archery Edge 320

Diamond Infinite Edge Pro

Diamond Archery Infinite Edge PRO

Diamond’s Infinite Edge Pro is very closely related to the company’s original Edge model, which was so highly regarded by consumers that it helped propel Diamond to international success.

The Infinite Edge Pro serves as an upgraded version of the original Edge models, yet features across the board performance upgrades that consumers will likely appreciate.

Much of the Infinite Edge Pro’s appeal lies in its significant range of adjustability. With a 13”-31” range of draw length adjustability, and draw weight range of 5-70 pounds, the number of archers that the Infinite Edge will not fit is few and far between.

Another key feature of the Infinite Edge Pro is its relatively compact design. Weighing in at only 3.2 pounds and measuring a mere 31” from axle-to-axle (read.. perfect compound bows for women).

This bow is perfect for hunting from confined quarters such as ground blinds or in a minimally sized treestand.
