The TCM-1 is a new current meter that is ideal for measuring water velocity from inland to the edge of the continental shelf. The simple design and lower cost of the TCM-1 make it feasible to measure current in many locations simultaneously.The core of the TCM-1 is the MAT-1 Data Logger.  The MAT-1 data logger was designed for NOAA and is ideally suited as the "brains" of a tilt current meter. The TCM-1 is field configurable for either low or high current range my simply adding or removing a calibrated ballast. Housed rugged PVC, with no external sensors, the TCM-1 is easy to deploy and recover. The built-in data logger includes a USB communication interface, a microSD flash memory card, and a long-life lithium battery. Key Features & Benefits
