Our Review of the Suunto t3 and t3c
Select Models on sale for $134.99-$149.99! Regularly priced at $169.99 Save up to $35 (20%)
Suunto t3c Black Arrow: Suunto celebrates serving as the official timing and data partner of the International Triathlon Union (ITU) with the limited edition Suunto t3c Black Arrow. The Black Arrow combines the same leading edge technology you expect in the Suunto t3c with an urban design at home in the gym and the city.
At one point a fitness enthusiast who wanted to monitor and track their heart rate, caloric burn, and other exercise data would need a tangle of electrodes, complex equipment, and extensive personal guidance from a certified fitness trainer. Today, all you need is a Suunto T3c, a PC, and one or more accessories to create an optimal training range that outlines your ideal energy expenditure and muscle exertion while preventing you from overworking and damaging your muscles.
For women, the Suunto t3c offers select styles designed by women for women. These styles feature softer, narrower wrist straps for improved fit and comfort along with enhanced graphics and colors. You get a more feminine feel without compromising performance.
Turn your Suunto t3c into a GPS Watch with a Suunto GPS POD. The GPS POD tracks speed and distance across a wide variety of outdoor activities, including hiking and cycling.
Note: Also available is the Suunto t3. There are a few key differences between the t3 and t3c Suunto watches:
- The t3 includes a heart rate belt; however, the heart rate belt is not the same comfort heart rate belt that comes with the t3c.
- The t3c allows you to choose which workout logs to delete. The t3 only deletes logs once the watch hits the 15-log memory capacity.

Standout Features:
- ANT comfort heart rate monitor belt features soft fabric for comfort and traction strips for a snug fit. The belt also provides interference free HR monitoring.
- The women's t3c watches features attractive graphics, unique detailing, and a softer, slimmer strap for an improved fit.
- Training Effect monitors your aerobic conditioning level.
- 15 logs of memory. Save all of your logs, or just selected ones. - Measures real time calories burned.
- Tracks speed and distance when paired with a Suunto POD (Peripheral Observation Device).
What Does the t3c do?
Training Effect: Suunto's exclusive Training Effect feature tells you whether you're training too little, too hard or staying within the zones for optimal performance. Training Effect uses a simple one - to - five scale to display how intense your workout is based on your current fitness level. And with alarms, you'll know as soon as you move up or down in intensity level.
Interference Free Heart Rate Monitoring: The ANT heart rate belt provides interference free HR monitoring anywhere and everywhere, remedying problems associated with previous HR monitors that were affected by power lines outside or electronic equipment inside the gym, making the t3c a valuable investment for those who love to train outdoors as well as in.
15 Log Memory: Record a personal training log of statistical data that reflects the progression of your aerobic health and performance capacity. And choose whether to save all of your logs or just select ones.
Activity Class: The Activity Class rates your current activity levels so that your Suunto watch knows your baseline activity level.
Track Data on Your PC (with the PC POD): Using the PC POD, keep detailed records of your workouts, heart rate, training effect, and calories burned. The PC POD comes with Suunto Training Manager Lite software.
Track Speed and Distance (with a Suunto POD): With a POD for runners, bicyclers and adventurers, your Suunto t3c watch tracks speed and distance during workouts. Want to purchase your t3c with a POD? Choose a t3c training pack, including the Suunto Cycling Pack, Suunto Running Pack, and the GPS enabled Multisport Pack.
Who is the Suunto t3c best for?
Runners, triathletes, spinners, mountain bikers, and anyone getting into shape benefits from the Suunto t3c. The Suunto t3c maximizes your fitness routine by providing up to the second information on your workouts. And with handy features like a lock button to prevent pressing the wrong button during your workout, the Suunto t3c is easy to use.
Use your Suunto t3c with the Suunto GPS POD for Geocaching! A high-tech quest, geocaching uses GPS coordinates to hide and find small treasures. Find out how to Geocache the Suunto way!
Compatible Suunto Training Packs:
Comparison: The Suunto t6c features many of the same features as the t3c, only it adds an altimeter and features 30 logs of memory. The Suunto t1c offers heart rate monitoring and real calories burned, but forgoes the t3c's training effect, interference free HR monitoring, 15 logs of memory, and PC interface.
Note: If you own a Suunto t3 and updated your heart rate monitor belt to the Comfort Heart Rate Belt, instructions for replacing the comfort belt's battery can be found on page 38 of the t3c instruction manual, available under the "Additional Info" tab.
