DMC IIB
The Nautilus DMCIIB is for the experienced user who wants complete control over his detector. The IIB offers exceptional performance, however, we do not recommend the detector to inexperienced users and those not confident in using a manual ground balancing detector.
The main differences between the IIB and IIBa is that the IIB user can adjust the sensitivity levels of each DMC circuit (ie All Metal and Motion Disc) rather than just controlling the overall gain of the detector via Transmit Power. IIB users also set the SLB function manually.
Price including stereo/mono headphones, VAT and delivery £649
Main Controls
Transmit Power Regulates the power and overall gain of the detector.
Threshold Sets the level of audio threshold.
Ground Balance Balances the detector to the level of mineralisation in the soil. This control effects both the All Metal and Motion Disc modes.
Discrimination Sets the level of discrimination the operator desires, runs from zero to aluminium bottle caps.
Sensitivity (Discriminate) Controls the sensitivity of the Discrimination mode.
Sensitivity (All Metal) Controls the sensitivity of the All Metal mode.
Other Controls
Auto-Tune on/off. Turns the detectors auto-tune function on or off, operates in the All Metal and Non-Motion Discrimination modes.
SLB (Search Loop Balance) on/off. Switches on and off the detectors SLB circuit. SLB “R” and “C”. These knobs are used to balance the coil.
Red re-tune button. Located on top of the hand-grip. Depressing the button restores the threshold when working without automatic tuning.
On/Off. Turn the detector on and off!
