V-Break: Variable Tone Break Point:
The ” V-BREAK ” function allows the user to change the audio response of certain targets. It makes it possible to determine to what conductivity threshold the target will sound in bass for an optimal recognition of the ferrous.
For example, if the V-BREAK is set to 50, all targets with a conductivity rating of less than 50 will have a low tone, targets of above 50 will keep their normal tone.
This function does not change the detector’s performance but allows the user to customize its metal detector in terms of having control of its target treasure .
The Land Ranger Pro is a multi-tone instrument, this means it produces different sounds depending on the metal detected. This is in the scale: low for the ferrous ones; medium for the aluminum and acute for the copper and the silver. It is an additional function to the conductivity index, it helps in providing valuable and more specific information about the detected object.
So how does this work? Depending on the detection program selected, the detector will emit 2 to 4 different tones that vary depending on the conductivity of the target. The more conductive the target is, the louder the sound. The less conductive the target is, the more the sound will go towards the bass.
Once a sound is emitted by the detector, the screen indicates the detected object’s conductivity. The conductivity index ranges from 0 to 99. The higher the index, the more conductive the target and vice versa.(See chart below for description of tones induced by different metals in differentmodes:)
Ground Grab – Ground Balance:
Most metal detectors are designed so as not to react to the natural mineralization of many terrains. However, setting is generally very high and not modifiable to have stable detectors on almost all the grounds.
The perverse effect of this is that a rejection of soil effects is too high and can cause a detector to lose up to 20% power.
Good news is that the Land Range Pro has adjustable ground effects. This provides an option for modifying the “Ground grab” depending on the terrain being explored which in turn yeilds the best performance of the detector.
The Conductivity Index:
The connectivity index scale is between 0 and 99 which appears roughly in the center of the screen. It is efficient at providing an idea of the type of metal detected.
If a metal is detected and the number at the scale is high, it means the metal is more conductive. For instance, a ferrous will be reported at around 0, aluminum st around 30, gold at around 40 and the most conquerors (copper, bronze, silver) will approach 80.
