Here’s a great gadget at a great price for clubs, classes, scout troops and packs, camps and family fun! Tune it to any quiet part of the 88-108 MHz FM band, hear the distinctive “beep-beep” modulation from the 1059, and let the kids use their own FM portable radios to discover the basics of direction-finding. Hide it indoors on rainy days! Includes board-mounted on-off switch and 9V battery snap. Use several to demonstrate triangulation. We recommend (undrilled, no holes) enclosure TPx-13 for this item.
