John Duke Rowing Machine

In late 1989, John Duke invented the water powered rowing machine to simulate the sound and feel of real rowing.  Contrary to modern ergometers, this is the basic with only a timer.  No odometer, no strength or resistance meter.  This is a rower for the sake of rowing.  Hear the water, feel the water and do it without the metrics.  Row Indoors.  $1500 BUY
