All-new patented 8×12″ Dual Field High-Q coil for improved depth and sensitivity. Bonus 7.5″ Dual Field concentric coil for a limited time!

To hunt all day, you need a lightweight detector that still provides high performance. The TDI SL 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.

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