Swimming Taught by Telephone, 1934

By means of a special headset and transmitter, a San Francisco coach is teaching swimming via telephone in 1934. The instructor stands on the edge of the pool and relays advice to his pupil in the water.

The inventor of the swimaphone tests his apparatus before sending his fair pupil out into deep water for instruction.

Specially prepared, waterproof transmitters and receivers, plus a length of telephone wire, comprise the set which operates on a charge of three volts. The advantage of the device is that faults are corrected while the swimmer is in action.
