Suunto HR belts will not transmit to a t-Series watch while underwater. In fact, I'm not sure I know of any wireless HR transmitters that DO transmit underwater.

That said, if your primary activity is swimming, you might consider the Suunto Smart Belt - or better yet, the forthcoming Memory Belt (coming in November) - which will record your workout data right in the belt. You can then later dowload to a PC to monitor your results. The Memory Belt also feeds to your t3, t4 or t6, so you can have real-time monitoring while engaged in out-of-the-water activities.

The "t" in t6 (if you don't want to get too technical) stands for "training". It actually refers to the time interval between two heartbeats, or EPOC. Measured to the millisecond, this interval allows you (using the included PC software) to assess your current fitness, set a proper training load, measure your actual fitness gain over time, and achieve your overall fitness goals.
