Archaeologist Jeff Spencer attends the Wrexham group's meetings on a regular basis.
He commended members for their first class organisational skills and dedicated hard work.
"They are a highly responsible group and I am happy to work with them. I come to see the group about once every three months," said Jeff, who is historic environment record officer for the Clwyd Powys Archaeological Trust.
Jeff said he was fascinated about one of the latest finds to be made by a member of the society, Julian Owen.
It is part of a horse harness which probably dates back somewhere between 700BC to around 43AD.
"This is a very exciting discovery which was made a couple of months ago in the late autumn – early winter.
"There are not many examples of this type," said Jeff.
The society's key phrase is "uncovering and recording our past".
Chairman Roy Griffiths said each member takes the activity very seriously.
The group is supported by the Portable Antiquities Scheme.
"We are well organised as a society to benefit the future of those items which were lost in the past. They wouldn't be found if it wasn't for our activities. We feel we are doing our bit for future generations," said Roy.
He stressed that members adhere to all the legislation in place governing their activities and are fully insured with the National Council for Metal Detecting.
The society has about 30 members and raises money for charities by putting on displays at village fetes.
It believes strongly in encouraging younger generations to take an interest in the past, and provides children with the opportunity to try metal detecting if there is an area of land available for them to use.
