Every new top of the line unit should come with a video made by the official testers explaining in detail what every facet does as an addendum to the manual which is brief at best. Seems like these units are excellent units but although they look easy to set up for those with years of experience the video data would help the newbie and oldbie quickly adjust to their new unit and get the most out of it from the get-go...Am sure better informed detectorists would post more positively which would equate to more sales and profits to the manufacturer..
