Ideal for finding lost items such as TV remote controls, glasses, keys, mobile. Tag up to 5 keys or other objects and find with audible warning within the home! Just press the button of the corresponding colour on the transmitter and the receiver will make a sound and flash a red LED, so you can find them quickly. The key finder with base support is also a good display for your house to ensure it doesn't get lost. The transmitter is removable from base and can be carried with you to find lost items. Great gift for all especially useful for elderly living with dementia. Batteries are included.
