LEFT/RIGHT Guidance and Audible Tone: the LCD centerline needle guides you to your target conductor.  

FULLY AUTOMATIC NO MANUAL ADJUSTMENTS-; Automatic gain control compensates for changes in conductor depth and peaking of signal over distance and provides you with just the right amount of power.  No manual adjustment is needed.

SIGNAL STRENGTH INDICATOR: a 3 digit signal strength reading gives the operator additional guidance and useful information.  The higher the number the closer to the center of your target.  The strength indicator also tells the operator that his transmitter should be moved closer leading to better accuracy and eliminating ghost readings from too weak a signal.

NEW VOLUME CONTROL– New for the 810 Dx is a 3 position volume control that the user can use to have High, Low or no sound relying only on the number display and the left/right guidance needle.

 DEPTH: Quick and easy Push Button Depth...Hold the locator directly over the target and push the button.  The depth now displays in easy to read Feet and Inches.

The 810Dx boasts a powerful 1-watt transmitter (maximum allowed by FCC regulation), upgraded from the previous 0.25-watt of the 810. Utilizing distinctive transmitter technology, the 810Dx is capable of three levels of output and has a new battery-conserving constant current circuitry. Sensing the resistance in the circuit, the transmitter applies the proper voltage to achieve a constant current output. The result is optimal signal strength without operator intervention for more productive operation. Transmitter power levels are easily selected using oversized buttons for a better tactile feel, even when using gloves.
The 810Dx locator includes the transmitter, receiver, conductive attachments, ground rod, carrying case, batteries and operation manual. 1-year warranty.
