Half Bates Rig
The rigging in the picture is called a “Half Bates rig”. The Bates Rig was originally designed in Australia many years ago. A similar concept is sometimes marketed here in the USA as a tackle berry or rapid release. The special quick release Bates buckle allows the rider to girth up and un-girth extremely quickly without much effort, due to the special Bates buckle and the leverage system. This rigging can be used on any Australian or Western saddle that is fitted with rigging dees, (large dee fitted between top saddle flap and under flap) and will greatly improve the girthing process over the standard Western rigging, and allows the saddle to be girthed tighter to help stop saddle slippage.
