Spares

This innovative new rubber has a brand new design in red, and it is designed to be worn looser on the tail. You don't need to use the ratchet system. Simply pull the strap through by hand and that should do the trick. You should be able to slide the sensor up the tail, but you will notice it will not slide back down due to the 'fins'. More comfortable for the cow, easier to attach and better grip. Longer strap also included.

Longer strap & Adjustable Ratchet for your Moocall device. Use this strap if you have bigger tailed animals and are struggling to close your Moocall with the regular strap. Important: Using a short strap on an animal with a larger tail may result in false alarms due to over tightening. If your ratchet has become worn or damaged and is no longer getting grip on the strap you can replace it by unscrewing it.
