The first in-house development

Between 1970 and 1973, VALLON launched the first products developed in-house. VALLON iron detectors were very popular for detecting contamination due to armed conflict: identifying and documenting sites containing weapons and ordnance. And the first metal detectors were used in agriculture and forestry. In those days, VALLON was also one of the leaders in developing and manufacturing robust, high-precision detectors.

1970 – the first product developed in-house: The EL 1300 iron detector for finding weapons and unexploded ordnance on land. That iron detector was the first in a successful product series whose technical advantages remain current today.

One year after launching the EL 1300 iron detector for applications on land, the EW 1500 followed. It was designed for use under water and in boreholes. The enhanced next generation, EW 1501 and EW 1502, were able to output graphical measurement curves using a thermal recorder.

The ML 1750 metal detector system was installed on the agricultural vehicles of various German manufacturers, enabling farmers to detect metal pieces in animal fodder and automatically remove them. As soon as a metal piece was detected, the combine harvester’s conveyor technology stopped so that the metal did not get ground up and land in the crop.

In collaboration with machine manufacturers, the system was later successfully integrated into the feed roller and maize chopper. Previously, metal pieces on farmland were regularly responsible for damages in the amount of several hundred thousand German marks (DM).

In 1973, VALLON launched the MB 1601, the company’s first hand-held metal detector. It was used to protect machines in the lumber and forest management industries. The MB 1601 made severe machine damage caused by metal slivers in wood a thing of the past.
