Locate new and potential customers with this spot finder! The wireless two-way finder features Bluetooth 4.0 technology that pairs with an app's "find mode" to trigger an alert to help find keys. "Tether mode" sends an alert before recipients accidentally leave valuables behind. It can be attached to keys, purses and more. The two-way technology can help find the valuable attached to the spot device or use the spot device to track down a paired phone. The Spot App is available for iOS and android (compatibility: iOS 8.0 or later and android OS 4.2.2 or later). It connects up to 120 feet from a phone or tablet and features a replaceable cell battery. Connect to your target audience in a new way!
