## Description

The Gymboss Charge is our most durable timer and was designed to be used under the most demanding conditions. While it is the same size and offers all the functions as our classic Gymboss, it is also weatherproof allowing for use in heavy continuous rain as well as extreme sweat and humid conditions. A backlit LCD makes it easy to see in any light exposure. It also offers the loudest beep alarm of any of our timers. Finally, the Charge has a built in rechargeable battery that will last for months on a single charge. *PLEASE NOTE - if the timer is not going to be used for an extended period of time, the battery must be charged at least once every six months.* For use with: HIIT, CrossFit, Cardio, Weightlifting, Strength Training, Kettlebells, Running, Learn-to-Run, Run-Walk-Run, MMA, Tabata, Boxing, Martial Arts and more.

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

## Questions & Answers

**Q: On the Charge can you turn the beep off and just use the vibrate notification?**
A: Yes. You can choose if you want your timer to beep high, beep low, vibrate, or a combination of beep and vibrate on all four of our models, Classic, Plus, Charge, and MiniMAX.

**Q: Can you feel this vibrate when using with the wrist watch adapter? I’m worried about not hearing the beeps if listening to music while running.**
A: Yes. That was exactly why it was invented. We wanted people to be able to feel the vibrate on the wristbone if they were using the timer  while running and listening to music.

**Q: How long will one charge last?**
A: Well it depends on how often a timer is being used of course. Generally the timer will last 3 to 6 months on a single charge.

**Q: Does Gymboss have one that can be used in a pool**
A: Not at this time no. The timers cannot be submerged in water.

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.
