hi guys craig here from nz i was wondering if anyone knew of anyone that still does mods to the tdi model detectors there was a guy reg in us that did a 2 stage mod but not anymore . i do have a gpx4500 etc but realy love the simplicity of the whites and high low conductors but wanting to mod them to make the threshold smother so i can run higher gain and more sensitivity . i have the oz series and a sl . the sl runs super smothe so doesnt really need the threshold mod but needs bit more punch on smaller gold any help would be great .
thanks craig
