The 1236-X2 does this by providing you a wealth of powerfully, well designed instrument controls and features that give you maximum flexibility of adjustment to accommodate your unique style of detecting. These are the controls on your 1236-X2 . Sensitivity Control: Along with an increase in sensitivity to find those deeply buried targets, we’ve provided a versatile SENSITIVITY control to adjust the sensitivity when searching near large metallic objects or extremely trashy areas. At the maximum SENSITIVITY setting a slight amount of audio threshold is provided so the faintest of target signals can be heard. Dual Mode Discrimination: The 1236-X2 provides two powerful modes of discrimination for you to choose as you hunt in different environments. In both discrimination modes you can adjust the DISC control to accept certain types of metallic targets while simultaneously rejecting ground minerals, trash, and other less conductive metallic targets. With the SILENCER switch “off” the 1236-X2 operates in a classic 2nd derivative discrimination mode that allows all pops, clicks, and partial target responses to be heard for maximum target information. With the SILENCER switch “on” the 1236-X2 operates in a newly developed 3rd derivative SILENCER mode, eliminating all pops, clicks, and partial target responses for a quieter mode of operation. This mode of discrimination is especially useful for eliminating excessive pops and clicks heard when searching in extremely trashy areas. NOTES 1. Subject to improvement or modification without notice. 2. In Search Mode, the 1236-X2 operates under two modes of discrimination. With the SILENCER off, it operates in a classic 2nd derivative discrimination mode that allows all pops, clicks and partial target responses to be heard for maximum target information. With the SILENCER on, the 1236-X2 operates in 3rd derivative SILENCER mode. This is especially useful for eliminating noise in extremely trashy areas. 3. The Search Mode has a 416 Hz target response. The Pinpoint Mode has a Voltage Controlled Oscillator (VCO) target response that responds to the precise location of a target with increasing vo...
