Diamond Atomic Review

Editors' review

Most first bows handed to a small child are plastic toys with a bow-shaped silhouette. The Diamond Atomic is built the other way around. It carries an all-aluminum riser, aluminum cams and aluminum limb pockets - the same class of hardware Diamond uses on its adult bows - scaled down to a 1.9-pound bow that a four year old can hold up at full draw. Diamond has made it continuously since 2012, when it replaced the old Nuclear Ice as the entry point to the lineup, and the formula has not needed to change: one tiny bow that adjusts from a 6-pound, 12-inch backyard setting all the way to 29 pounds and a 24-inch draw, following a child from their very first arrow toward the day they move up to a full-size bow. For the parent who wants a real, durable first bow instead of a toy - one a five year old can grow into over several seasons - the Atomic is the answer Diamond has kept in the catalog for over a decade.

Finish

The Atomic ships in a spread of finishes aimed squarely at the kid who will carry it: a solid Black, Mossy Oak Break-Up Country for the young hunter-in-training, and brighter Orange and Purple among the six colors offered, so a child can pick a bow that feels like theirs rather than a hand-me-down. Earlier runs leaned on pink and blue limb graphics for the same reason, and the palette has always put color choice front and center because, on a youth bow, the color is the one decision the archer actually cares about. Diamond's dip finish holds up to the knocks a first bow inevitably takes - the drops, the dirt, the leaning against the garage wall. Both right-hand and left-hand versions are offered across the range, which matters more here than on an adult bow: a left-handed six year old should never be forced onto a right-handed grip while they are still learning which eye to aim with.

Riser

The riser is the whole argument for buying the Atomic over a big-box toy. It is machined aluminum, not molded plastic, and that choice runs through the entire bow - aluminum cams and aluminum limb pockets too. In my experience the single most common failure on a cheap kids' bow is not the string but a flexy plastic riser or plastic cam that cracks the first time the bow gets dropped off a tailgate; the Atomic is built to survive exactly that. The geometry is deliberately tiny - a 24-inch axle-to-axle length, the cam-to-cam measurement - which keeps the bow short and light in small hands and easy to manage in a backyard or a garage range. There is no accessory rail or adult mounting hardware here, and there does not need to be; what the riser delivers is the two things that actually matter for a child learning to shoot: it is light, and it is durable enough to take years of abuse from someone still figuring out how to hang a bow on a hook.

Grip

The grip is a small, direct-to-riser profile sized for a child's hand, which is exactly the right call for the Atomic's audience. A narrow grip lets a young shooter wrap the bow without the palm heel forcing a torqued, inconsistent hand position, and low-torque hand placement is one of the very first things that separates a kid who starts to group arrows from one who sprays them across the target. Because the grip is molded into the riser rather than bolted on, there is nothing to loosen or rattle as the bow gets handled hard. An adult helping a child set up will find the grip far too small for their own hand, but that is the point - this bow is scaled to a first grader, not a parent. Out of the box the grip needs no attention; it is built to be picked up and shot by the small hands it was designed for.

Limbs

The Atomic runs short youth limbs in aluminum pockets, tuned to cover a 6-to-29-pound draw-weight range on the limb bolts. That range is the number that defines the whole bow: a parent can start a small child at a genuine 6 pounds - light enough that a preschooler can draw it - and turn the bow up a few pounds each year as the kid gets stronger, all with an Allen wrench and no bow press. Getting from the backyard-starter weight to the 29-pound top is the arc this bow is built to walk, and the aluminum pockets keep the limbs located and consistent through all of it. Aluminum where the competition uses plastic is the recurring theme, and on the limb pockets it matters most, because that is the joint that takes the load every shot and the abuse every time the bow gets knocked over. For a household with more than one child, the same set of limbs quietly resets from a lighter little sibling to a stronger older one in a couple of minutes.

Eccentric System

The heart of the Atomic is a pair of aluminum cams with rotating-module draw-length adjustment. To change the draw length you loosen the module screws and rotate the module through the 12-to-24-inch range; there are no separate cams to buy and no press required, and the modules carry an A and a B position that together open up that full span. That press-free adjustment is the entire reason a single Atomic can fit a four year old and the same child three years later. Speed is not what this bow is about: Diamond rates it at 191 fps, but that figure is measured at the youth setup of 29 pounds and 24 inches with the included arrows, not the 30-inch, 70-pound IBO test an adult bow is quoted at - it is a learning and backyard number, and it is plenty for punching paper and plinking targets. Let-off - the percentage the holding weight drops to at full draw - runs 70 percent according to Diamond's own mod-post chart, even though the marketing spec sheet leaves the figure blank. That deep let-off matters more on a youth bow than on any adult rig: at a 20-pound setting a child holds only about six pounds at full draw, light enough to settle the pin and actually aim rather than shake against the peak weight, which is exactly what keeps a young shooter engaged instead of frustrated.

Draw Cycle/Shootability

What strikes me every time I hand a bow like this to a kid is how much the low starting weight changes everything about the experience. Set the Atomic to 6 or 8 pounds and a small child can draw it, hold it steady, and settle a shot without their whole frame shaking by the tenth arrow - which is the difference between a kid who wants to keep shooting and one who puts the bow down frustrated. The draw itself is short and light with no aggressive hump to fight, appropriate for hands that are still learning the motion, and the rotating-module draw stop can be set right where a small shooter's anchor naturally falls instead of forcing them to overreach. The 70 percent let-off then drops the holding weight to a small fraction of the peak, so the child settles into the shot and steadies the pin instead of fighting the bow at the moment they should be aiming. At release the 1.9-pound bow is light enough to stay controlled in a small hand, and the shot is quiet and mild - this is not a bow that will startle a beginner. None of this makes the Atomic a performance instrument; it makes it exactly what a first bow should be, which is forgiving, unintimidating, and easy for a child to succeed with early.

Usage Scenarios

Picture a parent setting up a first real bow for a five year old: dial the Atomic to 6 pounds and a 12-inch draw, and the child is putting arrows into a backyard target the same afternoon, the 1.9-pound bow light enough that their form holds up shot after shot. Two years on, the same bow rotates out to a longer draw and turns up a few pounds on the limb bolts for a growing seven or eight year old shooting a scholastic or backyard-club program. In a household with siblings, one Atomic quietly resets from a lighter little one to a stronger older kid between turns. It is built for backyard practice, learn-to-shoot programs, indoor lanes and pure recreational plinking - the places a child actually learns the sport. What it is not is a hunting bow: the 191 fps and the 29-pound ceiling are built for form and fun, and a kid who is ready to chase small game or deer has outgrown the platform and should move up. That next step is where a bow like the Diamond Radian, which carries the same grow-with-you idea to higher weights and speeds, takes over.

The youth-bow shelf has a few genuine alternatives, and the choice comes down to one question: how young and small is the archer. The Diamond Atomic reaches the youngest - its 6-pound, 12-inch-draw floor lets a preschooler shoot a real compound, and nothing else here comes close to that starting point. The Bear Limitless is the grow-toward-adult option: it runs a 25-to-50-pound draw weight and a 19-to-29-inch draw at a 265 fps rating for a $199.99 ready-to-hunt package, so it is cheaper and faster and will carry a bigger kid to a real hunting weight - but it starts at 25 pounds and a 19-inch draw, right about where the Atomic tops out, so it will not fit a genuinely small child. The Mission Menace is the classic grow-with-you youth bow from Mission by Mathews, adjusting across a 16-to-52-pound weight and a 17-to-30-inch draw so a child can shoot it from their youth years into adult hunting poundage on one bow; like the Limitless, its floor sits well above the Atomic's, aiming it at an older kid than the Atomic's core buyer. So the decision comes down to priorities: the Diamond Atomic for the parent starting a genuinely small child who needs the lowest weight and shortest draw; the Bear Limitless for a bigger kid who wants the cheapest bow that still climbs to a hunting weight; and the Mission Menace for the family that wants one bow to carry a child all the way from youth archery into adult hunting.

Summary

The Diamond Atomic is the bow to reach for when the archer is genuinely small, and it solves that job better than anything near its $269 price. Its 12-to-24-inch draw and 6-to-29-pound range adjust at home without a press, so one 1.9-pound bow follows a child from a preschooler's first backyard arrows toward the day they move up to a full-size bow, and Diamond has kept the formula in the catalog continuously since 2012 for good reason. The all-aluminum riser, cams and limb pockets are the heart of it - on a bow that will be dropped, shared between siblings and left out in the yard, building it out of metal instead of plastic is the choice that keeps it shooting for years. The 191 fps rating marks it plainly as a learning and backyard bow rather than a hunting rig, which is exactly what a first bow should be, and the deep 70 percent let-off keeps a small child steady at full draw. What I keep coming back to is how low it starts: a 6-pound, 12-inch setting puts a real compound in the hands of a four or five year old, and very few bows at any price genuinely do that. It is an excellent choice for the parent putting a durable, real first bow in a small child's hands with room to grow, particularly strong for households sharing one bow between siblings. Families who need the range to reach a full hunting weight should also look at the Bear Limitless, and those who want one bow to carry a child from youth archery all the way into adult hunting might prefer the Mission Menace.
