Like most archers out there, I keep my eye open for new products and equipment for our great sport.  When I heard BowTech had bought the archery company Diamond, I knew that good things were going to happen.    Diamond by BowTech is a Design, Engineering, Manufacturing, and Customer Care company that focuses on two critical customer concerns: the quest for the highest performing and most dependable bow equipment in the world and the need for unparalleled follow-up service after the sale. (Web site:

Like the BowTech line of bows, Diamond has released their own “patriotic” line as well, with names such as: Liberty, Victory, Justice, and Triumph.  For this evaluation, we will be talking about the 33-Ό inch axel-to-axel Diamond Liberty.  A bow, which this evaluator feels is the smoothest drawing bow on the market.


Just like all the other evaluations that I do, it starts when the package arrives.  You can tell a lot about a company, by how they package their items. Diamond by BowTech did not let me down.  Each bow comes in a custom suspension protection sleeve.  Made for your bow, this sleeve prevents the bow from bouncing around and being damaged during shipment.  I felt this was important to add into my evaluation.  If a company is willing to ensure that their equipment arrives to you safe, they will continue to provide great customer service and support throughout the life of your bow.


  • Matching BowTech on all standards, the Liberty is machined from 6061-T6 aluminum.
  • The sight window is just over 6 ½ inches and accommodates the largest sights on the market.
  • There are 12 cutouts along this 25 1/2-inch riser that reduce the overall weight of the whole bow, which I might add is only 3.9 pounds. 
  • The brace height of the liberty is 7 ½ inches and in combination with the length of the riser; it is one of the most forgiving bows on the market.
  • Instead of a label, the serial number is stamped into the riser.  This would help you in trying to recover a bow that might have been stolen or lost.
  • The slim wood grip has a narrow throat and flatter heel for absolute grip consistency.

Limbs/ Limb pockets

The Gordon Glass limbs are 13 inches and settled in limb pockets that are machined from the same 6061-T6 aluminum that the riser is made of.  The big advantage of Vertical Force Technology is the fact that your limbs do not have to bend far.  Since the riser is longer and the limbs are shorter on vertical limb bows, the limbs are more rigid and can store energy better. Upon release of the arrow, most of the energy is transferred into the arrow and not the bow.  The result is, little to no vibration transferred to the riser or your hand.  


The Liberty this year comes as a Single Cam called the Freedom Cam. The larger wheel/cam combo is designed to produce a new level of smoothness and a feel of effortless draw, yet the added benefit of adjustable let-off from 65% to 80%.

Hush Kit

Every Diamond bow comes with a factory installed Hush kit, which is a complete noise, oscillation, and vibration arresting system.  As you will later read, the hush kit not only made the bow ultra quiet, but it reduced shock and vibration to almost nothing.


The Mossy Oak finish is done with a process called Hydrographic Transfer.  Here is what happens during this process.  A film that contains the camouflage pattern on it is placed in a tank full of water.  The film dissolves, leaving only the pattern on the surface of the water.  Then, all the parts of the bow are dipped in the tank.  The pattern adheres itself to the part and creates a seamless, almost indestructible finish.  Just think of it as sticking your tongue to a flagpole in the winter, once you do it, it is hard to get it off.


Testing was done outside at distances from 10 to 20 yards.  The only thing I initially installed on the Liberty was a Trophy Ridge Dropzone rest for the first “feel” shots.  There was no need to install a nock point, for the folks at BowTech had already put one there.

I drew the bow to ensure the 29” draw was correct and found it was effortless to pull back.  Using my bow scale I found the poundage to be 70.3 lbs, which felt more like 60 lbs thanks to the efficiency of the Freedom Cam.

After that, I drew the bow using my release with my eyes closed.  I wanted to get the feel of the whole draw, and I can tell you that drawing this bow was like a walk in the park.  There is hardly a valley during the draw and once I was at the back, it was solid.  The bow felt firm in my hand and did not torque to the side if I re-adjusted my grip.  I must have done this 15 times and the anchor point never changed, nor did the draw length differ.

I have shot almost every make and model of bow that is out there, and I have to have a grip that feels perfect in my hand.  One thing that I have noticed in newer bows is the grips are always thin, which decreases the grip consistency.  This is not the case with the Liberty.  The flat back of the grip ensures that it does not move when drawn and the bow fits perfect every time I pick it up.

Once I paper tuned the bow, I was ready for shooting.

First, I wanted to determine speed.  The birth certificate that came with the bow had it shooting at 277 fps set at 71lbs with a 350-grain 29-inch arrow.  While shooting, I used three equally weighted 450-grain Carbon Express Maxima 350 arrows.  I shot a total of twelve times and the average speed was 262 fps.

After the speed test was complete, I installed my Trophy Ridge Matrix and Venom Peep Sight.  Once sighted in, I moved back to 20 yards.  I shot the bow over 100 times listening for noise and feeling for any kick.  I have to say that I was impressed with the quietness of the bow and the fact that when I shot, it did not move.  Even more, this was just with the factory hush kit installed, which means no need to spend more money on noise dampening items.  Not wanting to be bias in my decision, I had my wife Jodi listen as I shot the Liberty along with a couple other bows that I have from different manufactures.  Using the same arrows, I had her stand in the same three spots around me each time. The results were conclusive; the Liberty was the quietest of all three.  As a matter of fact, it beat them all hands down!

If you can’t tell by now, I am very impressed with the Liberty.  From the moment that I took it out of the box, I knew that I was holding a piece of quality workmanship.   Unlike other expansion companies who build “cheaper” bows, Diamond releases quality.  They offer a lifetime warranty to the original owner and will bend over backwards to help you with any problem you have. With quality service and equipment like that, they have my thumbs up!!
