Anyone use a pet tracker?

My dumbass cat wanders off every once in a while and I usually spend a few hours searching for him while my gf panics . Eventually he lumbers back home when he gets hungry.

It seems like a billion dollar idea to have a little tag attached to their collar and monitored from your cellphone to track location.
The only ones I have seen are GPS units that are bulky and expensive or Apple airtags that have little range.
