Optional PODs (not included in standard package) to give the Suunto T4 heart rate monitor other capabilities: GPS POD, Bike POD, Foot POD and PC POD.
Note that the features in bold above show the features found in Suunto T4 but not in Suunto T3.
Training Effect: This feature is quite unique. Using your personal fitness profile, the Suunto T4 heart rate monitor analyzes your heart rate performance and displays that on a Training Effect scale between 1 to 5. It tells you bascially how much your current work out has improved your aerobic condition. If you want to maintain your aerobic fitness, train until your TE measures 2.0 to 2.9. If you want to improve it but not at too quick a pace, train until it measures 3.0 to 3.9 and so on. You can also (if you wish) pre-set your training target before your workout. Overall the Training Effect feature is great for many people who want some guidance on whether they have trained enough to achieve their aims.
Suunto Coach: This feature analyses your current and past performance and produces a personal 5-day training plan. It makes recommendations for your workout: exercise frequency, duration and intensity (via target Training Effect). It also schedules rest days for you. You can follow the recommendations or decide on your own training details. If you do something different from suggested, Suunto Coach automatically re-adjust the plan for your next 5 days so that your plan is always updated, taking into account your actual training.
Optional PODs: There are 3 types of PODs (Peripheral Observation Devices) for speed and distance measurements: GPS POD, Bike POD and Foot POD. If you use one of them, you can set your speed limits and also review your speed and distance information real time and also in summary. In addition a number of other facilities such as Autolap etc become available.
PC POD enables data download directly from your chest belt to the PC, allowing real time monitoring of your heart rate on the PC screen. The T4 wrist watch unit can also connect to the PC via the PC POD. The PC POD comes with a special monitoring software.
Summary
The Suunto T4 heart rate monitor takes the T3 one step further by bringing in a planning tool, the Suunto Coach, to your heart rate monitor training. It retains all the other main features of the T3, for example, Training Effect, digital transmission, 15 session memory, interval timer and POD compatibility.
