Designed for athletes in training, the Suunto t4c wrist-top computer monitors your progress and makes intelligent workout recommendations for frequency, duration, and intensity, helping you optimize your workout routine. The unit is built around the Suunto Coach feature, which generates a five-day plan for improving your aerobic condition. Employing real-time Training Effect technology, it tells you which days to work out and then advises you information on duration and intensity. If you accept a recommended workout, the Suunto t4c guides you through the session to make sure you receive the proper training load. If you decline a recommended workout in favor of a rest day or non-recommended workout, however, the t4c continues to monitor and adapt by adjusting your five-day plan accordingly.
The Suunto t4c is compatible with a number of separately sold training pods that measure your speed, distance, or cycling cadence, helping expand your heart rate monitor's capabilities and sending real-time data to your wrist. The pods rely on interference-free digital ANT transmission and coding technology, which guarantees zero interference with other nearby heart rate monitors, power lines, and gym machines. Other details include real-time displays on heart rate and calories burned, zone training, dual time readings, a calendar, an alarm, a training logbook, and a stopwatch with splits and laps. Available in such colors as black volcano and black frost, the Suunto t4c carries a two-year warranty. Suunto belts are sold separately.

About Suunto
Suunto was founded in 1936 by outdoors man and a keen orienteering enthusiast, Tuomas Vohlonen, who had long been bothered by a problem: the inaccuracy of traditional dry compasses and their lack of steady needle operation. Being an engineer with an inventive turn of mind, he discovered and patented the production method for a much steadier needle, better readings, and a new level of accuracy.
By 1950 the company was exporting compasses to over 50 countries around the world, including Canada and the United States. In 1952, Helsinki was hosting the Olympic Games, and the torches carried to light the Olympic flame were Suunto products. The next step was improving the stability and accuracy of marine compasses. The first marine compass, the Suunto K-12, was launched onto the market in 1953. In 1957, Suunto started manufacturing hypsometers, which measure the height of trees.
In the 1960s, the compass range grew further and Suunto introduced its first diving compass--initiated by the divers themselves. A British sports diver attached a Suunto compass to his wrist and found that the device also worked underwater. Thanks to his feedback and initiatives, the new business category was found. Suunto's exports and business grew steadily and Suunto then focused on combining its strength in precision mechanics with new skills in electronics. Accuracy, reliability, and ruggedness have been Suunto's key values from the very beginning of the company history.
Today, Suunto is a leading designer and manufacturer of sports instruments for training, diving, mountaineering, hiking, skiing, sailing, and golf. True to its roots, Suunto is today the world's biggest compass manufacturer. Prized for their design, accuracy and dependability, Suunto sports instruments combine the aesthetics and functionality of watches with sport-specific computers that help athletes at all levels analyze and improve performance. Headquartered in Vantaa, Finland, Suunto employs more than 500 people worldwide and distributes its products to nearly 60 countries. The company is a subsidiary of Helsinki-based Amer Sports Corporation with the sister brands Wilson, Salomon, Atomic, Precor, and Mavic.
The next generation of the T4 Suunto Watch, the T4c maximizes your comfort. Featuring Suunto's remarkable new Comfort Belt made from soft fabrics, the T4c makes a heart rate monitor easier to wear. Traction strips keep the belt snug; while the removable transmitter module lets you throw your comfort belt right in the washing machine. The comfort belt may also be purchased separately for those wanting a spare or to upgrade from their older T4 heart rate monitor strap. Suunto T4 Environment: Endurance sports with competitive endeavor: running, cycling, Nordic skiing, triathlons and more. The Suunto T4 is another excellent addition to Suunto's growing line of fitness training wristop computers. Like all of Suunto's t-Series training watches (the T1c, T3c, T4c, and the original T6c) the T4c monitors your heart rate and caloric burn to assist you in developing an optimized fitness regimen. It also provides you with information about the progression and effects of your training through constant feedback on how to maximize the intensity of your exercises without the over exertion of your heart and muscles. This "intelligent sports watch", via a simple cell-phone like interface, offers clear advice on how to get the most out of each and every workout. Features of the Suunto T4 extend far beyond just a simple heart rate monitor and calorie counter. You get all the excellent training features of the Suunto T3, plus Suunto Coach. Suunto Coach doesn't exist on any other watch in the extensive Suunto catalog. 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. The T4 also monitors the "training effect" of your workouts, analyzing your performance heartbeat by heartbeat, and illustrating the improvement of your body's aerobic conditioning with a simple one-to-five scale.
