There have been rumours for some time that Apple are to release a “tag” for attaching to stuff that may get lost so it can be located to within cms - allegedly. You can read about it here at Apple tags as well as other devices. Mooted to cost £30-£50 and may be a better bet than Tiles for iPhone/iPad owners.
Signs are the tags may appear quite soon so may be a useful investment for those with expensive drones and with a propensity to losing them.
