<P>PROBLEM TO BE SOLVED: To provide an information display system feasible at low cost for allowing a diver under diving to reliably confirm his way home by easier operation. <P>SOLUTION: The information display system includes a dive computer 2 stored in a waterproof case 21, which includes a display with crystal display panel 211 for displaying various information and a switch 23 operable from outside the case 21. The dive computer 2 detects direction of course, defines the detected direction as an outward route direction depending on operation to indicate azimuth setting by using the switch 23, and then computes a homeward route direction from this outward route direction, displaying the computed homeward route direction on the crystal display panel 211. <P>COPYRIGHT: (C)2009,JPO&INPIT |
