The ring applicator features the same shape as the Biotorus, without the built-in LT99 control unit. This is an accessory which can be purchased for use with the LT99 Control Unit, allowing for additional targeting of the hip, shoulder, elbow and knee joints. You can also use it with the LT100 Biotorus or the Therapply PRO Kit, enabling you to target 2 areas simultaneously.
If you own the Therapply Max, you could disconnect the standard large applicator, and attach this ring applicator to target a shoulder, hip or elbow. Then, switch applicators and resume application to the leg or back with Therapply Max’s standard large applicator.
