About Polar
The first EKG accurate wireless heart rate monitor was invented by Polar back in 1977 as a training tool for the Finnish National Cross Country Ski Team. The concept of "intensity training" by heart rate swept the athletic world in the eighties. By the 1990s, individuals were looking to heart rate monitors not only for performance training needs, but also for achieving everyday fitness goals. Today, the same concept of heart rate training is being used by world-class athletes as well as everyday people trying to lose weight. Polar is the leading brand among consumers, coaches, and personal trainers worldwide and the company is committed to not only producing the best products, but also being the leading educator on the benefits of heart rate based exercise.

The Suunto GPS POD employs the Global Positioning System to track speed and distance across a wide variety of outdoor activities including hiking, cycling, cross-country skiing, inline skating and kayaking. It attaches to your upper body using the included flexible fabric band or clip, and it's powered by two AAA batteries that provide up to 10 hours of use.

More than a heart rate monitor, the Suunto T4 Wristop Computer helps you train with confidence by providing real-time information on the aerobic benefit of each workout. Are you over or under-training? Sweating hard enough to reach your goals? The Suunto T4 knows and tells with real-time Training Effect.

More powerful than traditional zone training systems, Training Effect keeps you on-target for achieving your goal, whether it's weight loss, cardiovascular health, or shaving minutes off a marathon. By working from your personal fitness profile, the Suunto T4 analyzes your heartbeats and translates the data into a simple, one-to-five Training Effect scale. As a personal training guide, Training Effect is relative to each user. While a novice runner might achieve a TE of 4.0 on a four-mile jog, a professional runner might have to complete an uphill marathon to get the same reading. Both runners will have to exercise hard to achieve a TE of 4.0.

Using the enhanced Suunto Coach feature, the Suunto T4 generates a personalized 5-day training plan. The program helps you maintain a balance between workout and rest and makes intelligent recommendations for exercise frequency, duration, and intensity. Suunto Coach now gives you even better guidance, prescribing more training volume on higher program levels. By monitoring your Training Effect, it suggests which days to work out on and which days to rest.

You can follow the recommendations or vary the training intensity or duration to suit your mood. The Suunto T4 Coach adapts your program according to your actual training. If your activity level decreases, the Suunto Coach monitors and adapts, adjusting your plan for the next five days to ensure you get the right amount of exercise in each phase of training.

In addition to Training Effect and Coach features, the Suunto T4 displays heart rate, calories burned, and zone training. It also shows speed and distance with optional Suunto PODs. The onboard logbook has a 15-workout memory. Additional functions include dual time, date, alarm, and a stopwatch with split/lap.

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.
