  3. very good machine all round usage 5 Star Review

    Posted by on 31st Jan 2018

    The ace 300i is very easy to use ,clear crisp sound through head phones and even without head phones still clear and loud enabling you to pick the tones easily. The controls on the unit are easy to use and read. I would have no issues recommending this to anybody wishing to make a start in metal detecting. The kit is worth the investment as stater pack with supplied accessories.

  4. very good beginners machine 5 Star Review

    Posted by on 30th Jan 2017

    I purchased this machine with knowing too much about the hobby, but I have always wanted one so I went ahead and bought this machine. My reasoning for buying this detector were the positive reviews that seemed to be on every website I visited, so I went with my gut and bought this detector along with a pro pointer. I have mainly been using it at the beach in the dry sand, and haven't had a single problem with it so far. Would recommend for any beginners looking to pick up another hobby
