Great show. People who do metal detecting such as myself will probably get a much larger kick out of it, but I feel it's worth posting. The entirety of the series is on DailyMotion so you don't need to join Acorn or torrent it to watch it.
/u/Let Virtue Be Thy Guide has uploaded them sequentially in the best quality on dailymotion. I suggest only watching that /u/ uploaded if you decide to check it out.
