Let your heart rate monitor guide you like a personal trainer. The A3 has the new Zone Pointer™ feature that helps keep you in your Target Zone. Every exercise in your TZ puts you one step closer to your goal. File storage allows you to view previous workout data to help establish goals for your current workout.
Weaknesses: Build quality is poor. Wrist strap failed where it connects to watch. One of the buttons developed a crack even though the button was not used much. Chest strap does not have replaceable battery. Watch died after water leaked into it.
Bottom Line:
The A3 is accurate while it works. Not attractive.
THe A5.1 spring tension range is 12-18 Nm. The A3.1 is 8-12 Nm.
