The difference between our trackleCatch and trackleRegular is the following:
In our trackleCatch there is a small hole in the lower area where a removal cord can be attached to remove the sensor easily like a tampon. Many new customers therefore opt for the trackleCatch.
The trackleRegular does not have this hole and can be removed using two fingers on the grip area. With a little practice, this is no problem. By the way, the trackleCatch can of course also be used without the removal cord.
