Which product for Triathlon training and Heart Rate monitoring?
I'm looking for a fitness wearable to accomplish two things:
1) Most importantly, help me determine my heart rate during various physical activities (running, jogging, hiking, walking, cycling, and if possible, swimming).
2) Help me track my stats for Triathlon training (distance, times, pace, calories)
I'm looking at either the TomTom Multi-Sport GPS Watch with Heart Rate Monitor or the TomTom Spark 3 Cardio, GPS Fitness Watch + Heart Rate Monitor. Here are the links...
I understand that the Spark 3 Cardio doesn't do heart rate monitoring in the water because it uses a wrist-based (likely optical?) heart rate monitoring mechanism which is subject to interference from significant moisture, let alone submergence in the pool.
My main question is, since the Multi-Sport watch uses a separate heart rate monitor device (presumably chest mounted? Unclear from the product page...), can it give me my heart rate while swimming?
Secondary question is, even for running/cycling etc., does either watch show the real-time heart rate on the watch display or is the heart rate data only visible after the fact, once data has been uploaded somewhere?
