In 2005 we  published the Heritage Action Artefact Erosion Counter (HAAEC), providing a real-time running total of the likely number of artefacts found by detectorists. Evidence from various surveys (including detectorists; ones) show that on average each active detectorist finds at least 30.5 recordable artefacts per year and we assumed at the time there were 8,000 active detectorists, hence the rate of “tick”.

The resultant total now stands at close to 6.3 million recordable artefacts dug up since PAS was formed (compared with 1.5 million recordable artefacts recorded in the PAS database.) However, there are now perhaps 27,000 active detectorists and accordingly in 2018 Paul Barford published a revised counter reflecting this growth.

The implications are very sobering and Paul has now prepared the graphic below showing how things will be in ten years assuming the same number of detectorists each finding the same number of artefacts per year.
