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 TCM-5 is a current meter that is designed to operate in the Abyssopelagic and Hadalpelagic Zones of the ocean up to a maximum of 10,000 meters depth.
