Gymboss Charge Interval Timer and Stopwatch - Black/Red Softcoat

La ventaja de que se recargable facilita las cosas. Muy recomendable.

Its compact size makes it easy to clip onto your waistband for hands-free use, which is especially convenient during exercises that require focus. The beeper and vibration functions provide clear signals for work and rest periods, making it easy to follow any training protocol without constantly checking your watch. and I just love it

Strumento ben fatto molto completo, carica molto duratura e retroilluminazione molto efficace e comoda ma l applique è poco funzionale e si sfila facilmente dagli abiti ! Quindi attenzione a non perderlo !

I actually use this for meditation, and it does exactly what I need -- auto-repeat on its countdown timer, which ensures I give equal time to each meditation technique. Very easy to use -- I never looked at the instructions -- and the auto repeat function is great, with options to set the alarm to vibrate, chime loud or soft; repeat 90 plus time; and set the number of alarms at the end of countdown, and the time between them. Should be great for interval training.

Quite easy to setup once you read the instructions. Bleeps are loud enough when running outdoors ( maybe too loud even on low ). Great little device if doing sets of exercises.
