I read with interest all your comments on thinning down your collection of metal detectors. As a relatively new person to this hobby, I am trying to decide which one of these beautiful beasts to buy. I won't be doing much beach detecting but it is not totally off the radar and I don't imagine I will come across much gold unless it is in the form of lost jewellery so I am just looking for a detector that can grow with my experience and not leave me feeling like I want to upgrade as I feeling like I have outgrown it. Any advice will be welcome. Thank you all.
