Future Aids, The Braille Superstore 1-800-987-1231 Wireless Sound Beacon Audible Pager: Locate Soccer Net, Luggage and More Picture Larger Picture - Listen to this Product Camping! Hiking! Horseback riding! Even ball games! The list is endless. No matter what outdoor sport you enjoy, you should grab one of these gadgets before you go. Our Wireless Sound Beacon is one of the most versatile toys we carry. The beacon itself is a box, measuring just over two inches wide and three inches long, and less than an inch thick. Place it on any flat surface, or attach it to almost any object, and take the hand-held remote with you. When you want to go back to the picnic table, find your backpack, pinpoint the lead horseback rider, or aim for the soccer net, just press the button on the remote control in your hand. The beacon will immediately emit a series of beeps, so you'll know exactly where the object in question is. On the back of the beacon, you'll find a belt-clip, so it's easy for someone to wear. The unit has a guaranteed range of 25 feet, and is loud enough to be easily heard. It even has an on-off switch to conserve battery power. A must-have for those of us who love the outdoors, handy for finding everyday objects like purses, and great if someone in your care is sick and wants to call you for help, this lightweight, portable unit is both cool and practical. Takes 2 AA batteries, not included. Measures about 3 in. by 2-1/2 in. by 1 in.
