Pretty much done for this year. We've had snow twice already and it's hitting the teens at night. Last season I got 106 bits for just under an ounce and this year I only detected 40 bits for just over an ounce so an improvement over my 1st season! 18 bits from Montana and 22 bits from Idaho. FULL DISCLOSURE: 1 gram of the tiniest bits came from crack scratching/panning in the creek. I had fun and met some locals from Helena area (BIG help) and that helped me stumble onto the two bigger pieces (25g/4.5g) that saved my season. As long as I can improve weight at the end of season over the last I've reached the main goal.
good luck guys......

All-new patented 8"×12″ Dual Field 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 with its waterproof 7.5" x 12” High-Q 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.

However, performance can vary and the pulse delay may have to be advanced to compensate for coil differences that result in overload readings.
Notes *The TDI is unique in that it can suppress audio responses into two different classes. Targets have a high tone or low tone audio depending on how the target relates to the ground balance setting. In general high conductive targets give a low tone and low conductive targets a high tone. The TDI can be set to allow for one response or the other. See White's TDI Coin Settings for more details on this control. *Notes on Technical Specifications - Detailed notes about the specifications listed in this chart.
