After many frustrating attemps to connect my wireless nokak / makro, wireless headphones to my Nokta impact metal detector, I finally worked it out. Simply select the wireless channeles on the impact and it picks up the headphones, as the video shows. I have tried several ways in the past mainly watching youtube videos, these have never worked for the version Im using which is the latest version as of today 28/09/2019. hope this video helps all the frusted times you guys have had in connecting. have fun.
