a tool for an athlete to help discover their true weaknesses, quantitatively assess training improvements and refine the focus of their training

a tool that measures real-time work

A device used to measure radio energy.

Instrument used to measure optical power or optical power loss over a fiber optic path. Can assess the performance of the optical terminal equipment by measuring the absolute power being injected into or emerging from the fiber network. When used with a light source, the combination can measure link loss to verify continuity and help assess the quality of the transmission path through the optical fiber.
