We offer 3  ratemeters all built by us,
RateMaster2, RateMate, & RateOar  


RateMaster 2


RateMaster 2 Features:

A modern ratemeter that gives you all the information you actually need in the boat, without gimmicks or complex displays.
Rate [8 -99] updates every stroke
Time[ to 99mins 59 secs]
10 memory sessions [ Rate and Time are stored at 12 sec intervals for recall] up to 85 mins total.
This means you can store up to 10 races or training pieces before you start to overwrite the first one. To replay you select the piece of rowing to recall and then scroll or index through the data. Very useful in heads or races for getting a quite accurate race time.
*Semi automatic operation with Countdown start if required or just start rowing to start clock after manual start up.,* Auto stop after 3 secs of not rowing. *Auto switchoff after some 5mins of non use- or manual switch off .

Battery life is 5yrs plus, depending on use - see note below. You should not really need to worry about the battery for many years, unless misused.

 Compact case 75 mm x 50mm x 30 mm deep, Clear 12mm high LCD display - 6 digits, Floats,
Velcro for universal mount on boat stretcher etc.
Robust Waterproof rubber plug connector.
Lithium Coin cell type battery , Neck cord available if required. Extra sensors available. 

Free Battery change - for the first 5 years we will replace, free of charge, the battery, if unit is posted to us from theUK. We can do this because a change should not be needed in that time! If you wish to change it yourself we will gladly give details. [Cost after 5 years is 5 inc post].
