Yeah, your probably right Eray ( Im being a little bit E-trac focused) , but as you say , theres no reason other companies could not be involved , in fact I am sure they would like the exposure. I have contacted Minelab a few times over the years and they have always been extremely helpful ( apparently providing as much assistance as possible to end users of their products is written into the companies Mission statement) so I reckon we might get some help from them. Thanks for your comment and suggestions, I'll wait and see what everyone else thinks , especially Buck and proceed from there. Maybe you can go and roofrock em for us LOL!....................Balf
