Strap on the shock-resistant wrist unit and simply place your fingers onto the conductive plates, to gain an Electrocardiograph (ECG) accurate heart rate reading. It takes just a matter of seconds for your current heart rate to be clearly displayed on the large LCD screen. A built-in stopwatch and calorie counter also help monitor your workout progress and work toward your fitness goals.
The Oregon Scientific SE138 is well suited for use in the swimming pool, where heart rate chest straps will not give accurate readings; the SE138 Oregon Contact HRM has not got a heart rate activation button, meaning that the user can gain an ECG accurate heart rate, without running the risk of damaging the watch.
