To hunt all day, you need a lightweight detector that still provides high performance. The TDI Pro Metal Detector has pulse induction power that provides unbeatable depth and sensitivity and is designed specifically for prospecting and identifying relics.

Special prospecting features make life easier, such full-control ground balance that filters out the iron mineralization of hot rocks, black sand, and other tough grounds.

This compact detector weighs only 3.5 pounds with its waterproof 12” Spider Search Coil, which offers deep detection depth. Other accessory coils are also available.

The rechargeable NIMH battery lasts up to 6 hours, and a backup AA battery back will power all-day exploration.
