Our Review of the Suunto t4 and t4c
On Sale for $149.99! Regularly priced at $219.99. Save $70 (32%) (t4 model only)
The Suunto t4c monitors your heart rate, caloric burn, and provides detailed information about the progression and effects of your training. Plus, the t4c helps whip you into shape with the Suunto Coach, which lets you know when and how intensely to work out.
Turn your Suunto t4c 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.
SUUNTO t4 RANKS #2 IN U.S. IN OUTSIDE MAGAZINE'S "O LIST"

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 t4c watches feature attractive graphics, unique detailing, and a softer, slimmer strap for an improved fit.
- Suunto Coach acts as your personal trainer.
- 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 Suunto POD (Peripheral Observation Device).
Note: Also available is the Suunto t4. There are a few key differences between the t4 and t4c Suunto watches:
- The t4 includes a heart rate belt; however, the heart rate belt is not the same comfort heart rate belt that comes with the t4c.
- The t4c allows you to choose which workout logs to delete. The t4 only deletes logs once the watch hits the 15-log memory capacity.
What Does the t4c 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 monitors your heartbeat by heartbeat performance and uses a simple one - to - five scale to display the improvement of your aerobic conditioning. And with alarms, you know as soon as you hit the next intensity level.
Suunto Coach: Suunto Coach is designed for athletes who are very serious about their training, but may not have a coach or personal trainer available to monitor and make suggestions about adjustments in their workout routine. Suunto Coach software uses American College of Sports Medicine (ACSM) guidelines to plan the optimal intensity and duration of your next workout as far as 5 days ahead. Your Suunto t4c adapts to your performance, maintaining an up-to-date plan of how to best utilize your next trip to the gym, trails, track, slopes, or whatever your preferred activity. If your workout exertion was above or below the optimal level, Suunto Coach will adjust the suggested intensity and duration of your next workout to compensate for the difference.
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 t4c a valuable investment for those who love to train outdoors as well as in.
Activity Class: The Activity Class rates your current activity levels so that your Suunto watch knows your baseline activity level.
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 certain ones.
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 the Suunto Training Manager Lite software.
Track Speed and Distance (with a Suunto POD): With a POD for runners, bicyclists, and adventurers, your Suunto t4c watch tracks speed and distance during workouts. Want to purchase your t4c with a POD? Choose a t4c training pack, including the Suunto Cycling Pack, Suunto Running Pack, and the GPS enabled Multisport Pack.
Who is the Suunto t4c best for?
Runners, triathletes, spinners, mountain bikers, and anyone getting into shape benefits from the Suunto t4c. The Suunto t4c 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 t4c transforms your training.
Use your Suunto t4c 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!

Comparison
For those who don't need the personal training benefits of the Suunto Coach, the Suunto t3c has all the great training, heart rate, and calorie monitoring features of the t4c, only without the Suunto Coach.
Note: If you own a Suunto t4 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 41 of the t4c instruction manual, available under the "Additional Info" tab.
