Tile Mate £23 www.thetileapp.com If you’ve ever lost a set of keys on a golf course you’ll know how utterly frustrating it is knowing your belongings are out there, but you can’t find them. So long as you have your phone and a Tile Mate attached to your keys Tile can help. Attach this tiny GPS tracker to your keyring so if you lose your keys you can locate them using an app. The system works in reverse, too, so if you lose your phone Tile will call your phone so you can hear the ring (a great reason never to leave your phone on silent). And because Tile comes in a number of sizes at a reasonable cost, we reckon if you leave your clubs outside the clubhouse while going in for postround drinks it would make sense slipping one into your golf bag. If it’s ever stolen you’d be able to let the police know what’s happened and at the very least track where it’s gone.
