Seat position measurement opens up another dimension of analysis. By comparing the velocities of the seat and oar, you can identify the proportion of the drive taken with the legs and trunk. The range of leg movement can be quantified and common faults identified, such as loss of control on the recovery, lifting on with the back, "bum-shoving", and poor connection in the water.
The sensor reports:
It uses non-contact technology, comprising a rail that tapes to the deck, and a module that clips between the axles of the seat. The enclosures are rugged and completely waterproof.
