Rebalance statically with the camera (racking it in the opposite direction), and spin the sled again. Better
or worse? Again, you have two choices.
Re-rack, rebalance, and spin again (and again!) until the sled pans flat. This should not take a lot of time.
When the battery is within about 1/4th inch of ideal, the sled will behave nicely and feel “sweet.”
Adding any accessory will affect both static and dynamic balance
How much? It depends on the mass and position of the object, and the masses and positions of
everything else on the sled.
You will discover that as the monitor is placed higher towards the camera, the closer the battery c.g. gets
to the center post, and the more the camera c.g. moves away from the post to the rear. See the diagrams.
With any given monitor position, the heavier the camera, the closer its c.g. will be to the center post.
As you extend the telescoping post, you will discover the battery needs to move slightly further to the
rear to maintain dynamic balance.

Three figures to study for understanding
dynamic balance.
The top figure looks like the Model One or the SK. The camera c.g.
is centered over the post; the monitor and battery are on the same
horizontal plane, and their common c.g. is in the post. This unit is in
dynamic balance and pans flat.
The second figure has the monitor raised a bit. This looks like most
Steadicam configurations, high or low mode. Note that the battery
c.g. is closer to the post, and the camera c.g. has moved to the rear.
Why? See the third figure.
In the third figure, the monitor has been raised all the way up in
front of the camera. It’s absurd, of course, but it makes a point.
Now the common monitor and camera c.g. is over the post, and the
battery’s c.g. is directly under the post.
So you can see that as the monitor is raised, the camera c.g. must
move to the rear and the battery c.g. must move towards the post.
With the Archer
2
(and most Steadicams), the monitor is always
raised above the battery. Therefore camera is always to the rear of
the centerpost.
