Just after the second world war, Walter Wisbey started making medical devices in his garden shed. He was a very skilled surgical instrument maker. As his company grew he developed a range of industrial visual inspection probes, based on medical inspection equipment. With the growing terrorist threat in the UK in the 1970s, these industrial inspection probes morphed into high threat search equipment, and when you work with high threat search teams, you start working with bomb disposal teams, and the hook and line system was born. We have continued to expand our range and today we still make search equipment but we also make the most advanced hook and line system in the world and unique robots.
