How it works
The patented Fluid Technology variable resistance system makes ingenious use of a twin-chamber tank.
Water can be transferred to and from the two chambers by means of a lever or dial operation. Water in the outer chamber provides resistance to paddles when rotated by the pulling force of the user. Any water in the inner “passive” chamber does not provide resistance. Thus the resistance can be varied through changing the water level in the outer tank and the effort of the user.
NOTE: The complete system holds 8 litres (= 8kg) of water.
