5.4 BIONIC STREAM
Use the operating mode Bionic Stream to detect recently buried gold objects, long-time buried
gold as well as golden artifacts that are buried at long distances.
Make sure you have plugged in the Long-Range Probe (L).
This operating mode allows horizontal probe orientation.
5.4.1 Calibrate Bionic Sensors
1 2
Start the operating mode Bionic Stream by
tapping on the option in the App main menu.
Grasp the handle with your leading hand.
Make sure that palm and fingers touch the
electrodes.

With the other hand, turn the Knob very
gently to calibrate the Bionic sensors. Set a value within the green range - ideally
reach the highest possible value close to
254 . Make sure to keep the value stable for at
least 3 seconds. Confirm with .
If contact to the electrodes is lost during calibrating or measuring, repeat the calibration by
tapping on .
5.4.2 Measurement Screen
Enable the laser pointer for 5 s as an additional tool for aiming at the target object.
You may correct the crosshairs position via Settings – see
4.6 Set Crosshairs Posi-
tion on page 17 .
Change Reticle (crosshairs): Tap to change the reticle design.
Choose from 5 different options. Your choice is saved automatically.
Recalibrate Bionic Sensors, see 5.4.1 Calibrate Bionic Sensors on page 24 .
Exit Bionic Stream and return to the main menu.
Before performing a measurement, make sure you have set the crosshairs position according to
your planned scan zone. You may recalibrate the crosshairs whenever you like.
5.4.3 Perform Triangulation Measurement
Triangulation (or Cross Bearing) uses two or more points simultaneously to fix a position. This procedure helps to determine a potential target spot more precisely and to verify detected target spots.

Hold the Probe horizontally. Scan the area from the first position. Move the Probe slowly from side to side ... ... as well as up and down.

A hit is signaled by:
• acoustic feedback (if Sound is enabled)
• vibration (if Vibration is enabled)
• visual feedback (flashy crosshairs)
Perform a Control Scan from a different
direction at about 80 to 1600 ft (25 to 500 m)
distance from your first spot.
Before proceeding with the measurement,
you may recalibrate the crosshairs position –
see
4.6 Set Crosshairs Position on page 17
– and the Bionic Sensors – see 5.4.1 Calibrate
Bionic Sensors on page 24 .
As soon as you get a hit on the same target
spot, it is likely it is a potential target.
You may perform further control scans to
verify the target spot.
