Equipment used to recover PSAT tags. a Illustration of the CLS View Android application running on a cell phone and showing the locations of four PSATs floating at the surface (left) beside the CLS RXG135 receiver (right). b The RG58 directional antenna mounted above the bridge of the 45-foot longliner J Elizabeth. The white protruding cone above the silver base plate is the 0-degree reference for all angles. In combination, these products facilitated the rapid recovery of five PSATs at sea and subsequent analyses of the effects of temporal resolution on the detection and quantification of rapid, episodic vertical fish movements
