Bald Eagles..

Another piece of my tripod head is showing up tomorrow...now if we could get a clear day so we have some decent lighting.

This is a Wimberley Gimbal head. It allows you to effortlessly track your subject without the strain of holding your rig. The camera body and lens I am using is just over 12 pounds...makes it a bit tough to be steady while chasing the birds around.

This is a leveling head. No need to sit there and fiddle with the tripod legs to get the tripod level.

When you set up the Gimbal head/camera gear correctly the camera will stay level. Have heard of more than one photographer who has had his tripod topple over because the camera was on a tripod, pointing at the ground.
