Tiffin Davis & Sanford DRG/Q Professional Heavy Duty Tripod 

Closes down to 32" and Extends up to 68"

Good Working Condition ~ 

No Expert here but the Head appears to be Spring or Fluid loaded

When you pull down on the pan arm & release it the head "bounces" back to roughly level.

Twisting the pan arm slows & eventually locks the head in place ~ I see no other adjustments

Please ask any questions I wll answer what I can ~ Selling as is & as shown
