An adjustable mount for holding equipment or an equipment-holding arm at, for example, a hunting location such as a deer blind or a tree stand includes a base mounting bracket and an adjustable ball joint removably secured to the mounting bracket. The base mounting bracket is secured to something and can be left in place during the hunting season. The ball joint can be removed and taken with the user. In some configurations, the ball joint can be locked in a desired orientation which is maintained when the ball joint is removed from the base mounting bracket so that the desired orientation is reestablished when the user replaces the ball joint in the base mounting bracket. One version of the ball joint includes a piston cylinder used to release locking pressure to allow for adjustment. The piston cylinder can be pneumatic or hydraulic. A configuration of the base mounting bracket can be readily assembled from a collapsed flat configuration. An articulating equipment holding arm with first and second arms provides an adjustable mount for holding equipment.
