Pendulum, Black Obsidian Chamber
This Professional Pendulum is BEARING BALANCED. That means the pendulum chain rotates and swivels on a bearing that is inserted into the top cap(chamber cover). This results in a balanced swing that keeps the pendulum point, or bob, always aligned with the chain while swinging . This movement provides an instant and sensitive response. This alignment is excellent when using charts, always pointing in harmony with the arc of the swinging pendulum.
The chain is about 5 1/2 inches long. The pendulum bob is about 2 inches long, about 9/16 inches in diameter, and weighs about 16.5 grams.
The schamber is about 7 mm (9/32″) diameter and 9 mm (3/8″) high.
