Low Noise Drill (LND) Audio Probe Kit
Highly Sensitive Audio Probe for Covert Listening Operations Using the Low Noise Drilling System.
The Audio Probe is a high performance microphone probe for covert listening operations through small gaps, keyholes and the 1mm drilled hole following the use of the low noise drill.
The insertion probe is 5mm diameter x 330mm working length. A removable 1 metre lead connects the probe with an amplifier unit which is mountable on the belt of the operator.
A simple knob switch is on the front panel of the amplifier. Turn clockwise to switch on the unit, and further clockwise to increase the volume. A green LED indicator shows that the power is on.
Headphones are plugged into the front panel via the 3.5mm jack socket. To charge the unit, simply plug in the 3-pin connector from the supplied charger to the side of the unit.
The system will work for up to 7 hours from a full battery charge.
*Do not use the probe while it is charging. The microphone is so sensitive that you will only hear electrical noise from the charger!
