HC GPS Calibration Unit Hire

Hire the HC calibration unit - it uses a GPS to check your speed and calibrate your Coxmate HC.

All you do is clip it onto the normal HC mount, add your HC on top, plug in the GPS and set the calibration going. Then row 250m in one direction and the unit tells you when to spin and row 250m in the other direction and bingo, it's done and the calibration is stored in the HC.

You get one week's use and then you have to mail it back to us.

This will calibrate NK impellers and Coxmate micro-impellers.
