Converts and amplifies inaudible ultrasonic sound into audible “natural” sound for accurate diagnosis

  • Ultra-sensitive electronic circuitry detects sounds significantly beyond the range of the human ear
  • Self-adjusting AGC (Automatic Gain Control) circuitry automatically compensates for fluctuations in signal strength
  • 10 bar LED intensity indicator helps pinpoint the exact problem source
  • Precision-engineered air and contact probes optimize receiver versatility
  • Factory calibrated for optimal performance; does not require recalibration
  • Special emitter produces ultrasonic pulses to help receiver check for faulty seals, gaskets and weather stripping in passenger cabs, trailers and other non-pressurized enclosures
  • Rugged carrying case with contoured foam padding for safe storage and transportation
  • Receiver and emitter powered by standard 9-volt alkaline batteries (included

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 TP-9370 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 and weather stripping in cabs, trailers 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.
