The available tools may not be needed for all devices, but they are recommended for more targeted and direct treatment of trigger points (TrPs). The pen probes allow you to massage and treat TrPs simultaneously, encouraging better blood flow to bring nutrients to the area.

Other accessories, such as hand bars and foot plates, make it easier to treat yourself in positions where you cannot reach with the two probes together. They are also helpful when treating hands, feet, and your back on your own, as detailed in the manual.

Conductive gels are available on shopping sites like Amazon, and what to look for in a conductive gel is covered in the manual and on this website. 

Cable adapters are needed to attach the tools shown here if your devices work with 2mm pins.
