Diamond Archery Edge 320 Review [Hands-On]

There has been a substantial amount of talk in the archery world as of late surrounding the availability and popularity of new ultra-adjustable compound bows meant to cater to any archer. So when we were allowed to test out the Edge 320 R.A.K., we jumped on the chance for some hands-on experience. I actually went sent arrows downrange and gave this bow a proper chance. The following is a comprehensive look at what I found to be true of the Infinite Edge in terms of features and functionality.

The 320 offers a range of adjustability featuring a variable draw length of 15”-31” and a draw weight range of 7-70 pounds. Although these numbers themselves piqued my curiosity, I still wanted to find out if the Edge 320 lived up to all the hype surrounding it.

Coming into this Edge 320 bow review, I was quite excited to test the merits of the Edge 320. Diamond Archery’s history dates back to 1996, as a privately owned manufacturer of compound bows and archery equipment and products. The company was bought out by industry giant Bowtech in the mid-2000s and has operated as a company brand ever since. 

Diamond Archery is well renowned for producing some of the most versatile bows on the market while maintaining a working-man’s price point. The Edge 320 is based on the company’s very popular Edge platform and is billed as a performance-minded extension of this model. 

First Impression

When first holding the Edge 320 in my hand, I was quite impressed by its fit and finish. The particular bow I shot featured a Mossy Oak Break-Up finish, though both black and purple blaze finishes are also offered. 

I loved how light this bow was in the hand. It felt less than the 3.6 pounds the manufacturer lists. This is even lighter than some wood bows out there which is pretty wild. It felt fairly balanced overall, absent of the clunkiness and uneven weight distribution that is often common of bows in this price range that I’ve tested in the past.

Published Specs

Technical Features

The Edge 320 features several technical talking points worth mentioning. Much of this centers around the bow’s adaptability to the needs of virtually any archer. With such a vast range of adjustability to draw length (16 inches of draw length adjustment) and draw weight, this bow is well suited to use by men, women, and children alike. 

As far-reaching as these capabilities are, adjustments can be made on the fly and take very little time to complete. All you really need is a hex wrench.  It took only minutes to set the bow’s draw length and draw weight to my needs and I was ready to shoot. 

The modules associated with the Edge 320’s cams are of a rotating design. Making draw length adjustment is as simple as removing two screws, rotating the modules to align the indexing marks, and retightening the cam screws in place. 

The bow’s draw weight, not surprisingly, was trouble-free to adjust. To complete this task, turn the Edge 320’s limb bolts in/out in equal proportions to reach your desired weight. Both limb pockets feature an “EZ-Adjust” label that identifies the minimum and maximum adjustment thresholds. They also include reference marks which represents approximately 6.5 degrees of the bow’s overall peak draw weight. I think these are great features for someone starting out. You don’t have to go searching online or digging through the trash when you inevitably forget or need a quick reference.

It is worth noting, however, that the factory fitted EZ-Adjust label was little more than a sticker.  Although purely speculation, I would feel safe saying that this sticker would not fare well with time when exposed to the elements. 

Another great feature in the Edge 320’s design is relieving string tension without using a bow press. Each limb bolt can be backed off in an alternating fashion, to the point of creating slack in the bowstring. This allows for the installation of string accessories such as peeps and vibration dampeners but also the string itself. Order a string online and do it yourself to save quite a bit of money.

Shootability

With the quick installation of a D-Loop and peep sight, I was ready to take to the range.

Upon drawing the Edge 320, I instantly noted how smooth its overall draw cycle was. The rise to peak draw weight was even throughout the cycle, and the bow transitioned over into the valley as the cams actuated. 

The Synchronized Binary Cam System perfectly manages the whole process.

Upon reaching full draw, I was pleased to find that the bow featured a solid back wall. If the cam timing is correct, you will create a rock-solid back wall using the included limb stops.

This is a major plus in the Edge 320’s favor, as a spongy back wall can lead to an inconsistent anchor and negatively impact overall accuracy. 

The benefits associated with the bows 85% let-off also quickly became evident. Holding the bow at full draw was effortless. I was very pleased with the bow grip and didn’t feel like I would need to modify it in any way. Bow was easy to maintain proper form with and float the sight’s pin onto the target.

After touching off the trigger of my release, two factors became apparent. The first was: she’s quiet. Not much to be heard other than the arrow making contact with the target. The second: she’s dead in the hand. I wasn’t really expecting this bow to perform this well. It’s a mid-priced bow with high-priced performance. Seems like, to me, the high end technology has made it’s way into the low end.

Pros and Cons

PROS:

• 320 fps I.B.O. Speed for that “extra punch”
• Draw Weight Range
• Draw Length Range
• Aesthetically pleasing to me
• Smooth Draw Cycle and Solid Back Wall
• Comes With Sight, Rest, Stabilizer, and Quiver
• Dead Quiet

CONS:

• 3-Pin Sight Is Minimal In Features and Quality
• Quiver Mount and Cam-Lock Design Can Be Cumbersome
• EZ-Adjust Labeling Sticker Is Prone To Weathering

Infinite Edge Pro vs Edge 320

Let’s compare the Infinite Edge Pro and the Edge 320. Both bows are descendants of Diamonds’ popular Edge platform but there are some significant differences:

• The Edge 320 offers a brace height of 7.25″ whereas the Edge Pro model provides just a little less at 7″. In both cases, this seems like enough to make life easier for beginners and offer more accuracy when shooting.

• The Edge 320 has a longer ATA length than the Diamonds’ other models. This will be helpful to beginners who are looking for more accuracy and forgiveness when shooting.

• The most obvious difference is the speed. The Edge 320 offers a blazing speed of up to 320 fps. The effective let-off of 85% gives this bow a clear advantage above the other bows in the entire Edge series.
  
• Both bows offer very easy tuning

As of writing this post, the Edge 320 features the highest let-off available at 85%. The let-off is valuable for bowhunters since it can provide more hold time when you’re at full draw (especially if you’re drawing your bow to 70 pounds). If you are a target shooter this can be a detriment because less tension on your string at full draw can translate to less forgiveness on string path displacement due to anchor point pressure.

More speed means more momentum which means flatter shooting and harder hitting arrows. 320fps is the fastest of the Diamond line and likely targeted at hunter trying to penetrate game. Although there are faster bows out there, 320 fps is more than sufficient for hunting. 

Accessories

Along with a left handed model, the Edge 320 has a package option Diamond is calling the R.A.K. pack. It’s just a fancy marketing initialism that stands for “Ready, Aim, Kill”. Its ready out of the box and fully outfitted with a peep sight, rest, stabilizer, wrist sling, loop for the release, and quiver. This can come as a heavy advantage to some as it minimizes cost on additional accessories and gets you on the range or in the woods in record time.

The 3-pin Tundra sight included in the RAK pack is functional yet pretty barebones in its features. It will undoubtedly get the job done for hunting or even target shooting but it won’t include those extra niceties like tool-less adjustment, night lights, etc.

If you are planning to shoot longer distances or are used to a sight with all of the bells and whistles, you may want to rethink the RAK package deal.

As far as Diamond’s selection of arrow rest, I had no gripes to speak of. The Whisker Biscuit-style is a go-to, no frills, nothing to break, captive style rest. I’ve shot many a deer with this rest and although I prefer a drop-away I wouldn’t hesitate to take a Whisker Biscuit into the woods with me.

Whisker Biscuits have provided many archers with years of dedicated service and are favored by many for their simplicity and forgiveness in any field condition.

When it comes to the Edge 320 Package’s stabilizer, it is what it is. You’re not going to see a massive difference in shooting with or without it but I think the benefits of even a small stab like this are worth keeping around.

First, it gives you something extra to grab onto, even a nice edge to wrap around your neck when you arm is wore out from climbing hills with it.

You’ll also get some extra dampening from it as well and it holds the included wrist sling in place.

If there is any fault to be found in the Edge’s accessory package it would likely have to be the quiver. Although the quiver mount features multiple points of securement, there is still some limitation in how it can be affixed, leading to a somewhat noticeable offset toward the rear of the bow. Adding to that, the quiver’s cam-lock lever is also quite unconventional and can be cumbersome to use.

Overall Evaluation

After handling the Edge 320 in person, and putting it through its paces during some one-on-one range time, I have to say that I am very impressed. The compound bow itself looks excellent (mossy oak) and is a leader in ease of use, versatility and adjustability. If any area was lacking it would be in the accessories included in the compound bow package most notably the sight and quiver. This isn’t really surprising and is quite common in package bows no matter the brand. Any stock accessories can be replaced at a later date. 

I think you’ll be hard-pressed to find another bow that offers so much in the way of features, functions, and versatility as this bow, for anywhere near its price point. 

When you factor in the Edge 320’s blistering quick 320 fps I.B.O. speed, its weight of only 3.6 lbs, you are looking at a relative steal of a deal. Premium performance for an acceptable price!

different colors available

The Diamond Archery Infinite Edge is available for left-hand archers. This is an adjustable bow that offers extreme versatility and features a wide range of usability. This compound bow has been designed to suit the needs of amateurs and above while offering premium features for an exceptionally competitive price. I love the Bowtech Binary Cam System and the smooth draw cycle that comes with it. The let-off of up to 85% and the draw length and draw weight adjustability make this bow a great option for taller people too!
