A real capable looking machine with both DD and concentric coils available. I like. Haven't seen all the u-tube postings but don't recall any mention of SW versions or on screen Software version display. Or SW update capability. This will mean sending in for SW updates. Notching increments are way too broad. The weight and balance look ideal. Tone features I like. And the name and control panel front design are attractive. As this model evolves we will want wireless headphone option. The screw on coil connector is premo. Smaller coil options will be coming if this unit is successful. Does technetics have their own proprietary wireless headphone system?
