Function: 
(1) We add a function of indicator lights. These indicator lights show 20 different distances between the user with a receiver and the transmitter.
(2) Most common frequencies are Gold, Silver, Copper, Placer Gold, Tin, Aluminum and Jewel.
(3) Detecting Range: 100-1000m 
(4) Detecting Depth: 5-50m 
(5) After tracking target, you will have some idea of the identification and the exact pinpoint. 
(6) The face (front) of the transmitter has six LED's (channel indicator lights) across the top; each is labeled for a particular element.
