Counter sensors and very easy to install. Superb counter design! Instant operation without difficulty setting. Sensitive keys and easy to handle even with gloves. Information for the screen, very readable even in bright sunlight. Belt cardio comfortable to wear and easy to clean (sensor / transmitter removable).
Notice pretty comprehensive but difficult to handle: 6 languages on a single sheet of about 1 m² duplex, a galley to unfold and fold!
