Perfect for preventive maintenance
The ultrasonic range of the Marksman can actually pick up the sound of a blinking eye! This super-sensitive capability makes it one of most effective early warning systems to detect defects and malfunctions before they result in major breakdowns. It’s an ideal diagnostic tool that dramatically reduces equipment downtime and maintenance costs.

Highly accurate
The Marksman uses a two-tiered process to ensure accurate diagnosis. First, it converts inaudible ultrasonic sound into audible sound using a process known as heterodyning. Then, the unit’s Sound Signature Technology™ fine-tunes the audible sound into the "natural" sound emitted by the defect itself. In addition, a 10 bar LED display indicates the intensity of incoming signals from the problem source to ensure error-free diagnosis.

Extremely user friendly
The unit’s Automatic Gain Control (AGC) circuitry automatically adjusts to optimize signal sensitivity during every inspection. This simplifies operation and helps the user focus on the problem at hand — no need to play around with multiple knobs and buttons. Just turn on the Marksman and it’s ready to go!

Designed for optimal performance
The MDE-1000 Master Kit comes with an ultrasonic emitter and two probes that are specially designed to enhance the Marksman’s versatility. The emitter, which transmits ultrasonic pulses to the receiver, tests for faulty seals, gaskets or weather stripping in doors, windows, ductwork and other non-pressurized enclosures. The 12" air probe extends the receiver’s reach and helps isolate a leak among multiple suspect areas. The contact probe, when touched to an external surface, picks up and transmits ultrasonic sound from defective internal components without disassembly.

Portable
The Marksman, with its solid-state circuitry, is compact and lightweight. The receiver, weighing just 10 ounces, is perfect for prolonged, fatigue-free inspections.
