This Water-Reel Calculator slide rule was developed to supprt the installation of 'hard hose' travelers which displaced the Water-Winch units.

The difficult part of this development was to adjust to metric measurements for the hose. The hard hose concept was developed in Europe.

Rather than introduce a complete set of new hose measurements in the market, Kifco / Ag-Rain opted to stay with the metric sizes that were already being sold in the US.
