James Bond wannabes and serious adventurers alike should check out Suunto's new line of 'wrist-top computers,' which pack handy tools in digital watches. The top-of-the-line AdVizor can monitor the wearer's pulse, compute the average heart rate, and sound an alarm if a maximum rate is exceeded. Additionally, it has a digital compass and barometer, a chronograph with stopwatch and countdown functions, and an altimeter that shows the current altitude as well as the ascent/descent rate. The Navitec forgoes most of the AdVizor's features except the compass and chronograph. About $299 for the AdVizor; $165 for the Navitec; % Suunto USA at 800-543-9124.
