DESC: Introducing the PAG-40 new function-oriented models that improve on the basic PATHFINDER concept by providing altitude measurements up to 32,800 feet and other improved functions, plus a larger display panel with a dual-level display screen indicates direction readings by a pointer that seems to float above other display data. The result is more information in a format that is easier to read. In addition, direction, and altitude/barometric pressure readings can be triggered by pressing a single button, providing the information you need the instant you need it.- These features, and more, make this model a valuable tool that can provide that extra margin of assurance that your outdoor adventures will always be safe and successful.
