What is the definition of a "Binary Cam"? Are they all basically the same design or are there differnces?

Binaries, K8s, trinaries, 2.5s, etc etc are all Ketchum cams:wink:

What is the definition of a "Binary Cam"? Are they all basically the same design or are there differnces?

Single cam = Round metal thingy on top, also known as the idler wheel.
Metal thingy on the bottom is kindy irregular shaped.

Really long string.
Cable end loops form a Y-shape, and the end loops on the end of the Y-cable attach to the axle on top, where you have the metal round thingy.



Hybrid cam = Two metal irregular shaped metal thingys. Y-shaped cable.
The "cam" is on the bottom. The metal thingy on top
is connected to the metal thingy on the bottom with a cable.

Just like a bicycle chain connects the pedal gear to the rear wheel gear,
on a single speed bicycle. Pedal gear spins,
then the bicycle wheel gear in back must also spin because of the chain.

So,
when the cam on the bottom of a hybrid bow rotates,
the cable connects to the metal thingy on top, and the metal thingy on top must also rotate.

The two metal thingys on a hybrid bow are similar,
but not exactly the same.


Binary cam

The distinguishing factor for the binary cam system,
is that the two metal thingys are identical in shape.

Mirror images.

Top is the same as the bottom metal thingy,
except the bottom metal thingy is upside down.


Another distinguishing factor
is that the binary cam system does NOT use any Y-shaped cables.

In fact,
the top metal thingy is tied to the bottom metal thingy by a cable.

Bottom metal thingy is tied to the top metal thingy also by a cable.

Therefore,
if one metal thingy moves,
the other metal thingy must also move.


So, mirror image metal thingys
and NO Y-shaped cables = binary cam system.

Listen to the thingy. Remember, binary cams have superior nock travel. But they can have the oh so evil "cam lean". In reality it is limb torque. But this tunes perfect and shoots very consistent.

I like them, a lot. Good question. Remember, a true binary (BowTech) the top and bottom cams are identical, except for the draw stop on the top cam.

I don't understand your answer.

Your answer is a little to complicated could you make it more simple.

A guy named Ketchum patented slaved dual cams 20+/- yrs ago, all current patents on "binary" like cams site Ketchums patent on theirs.
IMO binaries are simply described by having both cams "tied" to each other, many are coming out with cams that are asymetrical, claiming that makes them different but they are pretty much the same, and are experienceing the exact same problems "binaries" have had(cam lean, tuning).
Its got to be the hottest cam system out right now as they produce great preformance and are popping up in many bow lines.

Who has the best binary cams?

"Best" is something you have to find out for yourself, I like Elites.

Its on the bottom on a lefty rig.

Have you shot the GTO? What is the hand shock comparable to?

Very similar to a vectrix, hardly any. It draws stiffer than a vectrix but its a bit faster too.
