Closing The Blind Spot

In the evolving landscape of Technical Surveillance Counter-Measures (TSCM), high-frequency detection has long been the standard. However, this focus often leaves a critical vulnerability: threat signals concealed at lower ultrasonic frequencies.

The Lockhart Ultrasonic is the latest addition to the Lockhart family, engineered specifically to bridge this gap. By visualising the ultrasonic spectrum (10kHz – 110kHz) with the same intuitive simplicity and rugged reliability operators expect from Lockhart, this device ensures no signal goes undetected.

Designed to operate in concert with other Lockhart TSCM search products, the Ultrasonic provides an essential additional layer of signals intelligence. It is the definitive complementary tool for performing characteristic and link detection, completing your security perimeter.

Why Choose Lockhart Ultrasonic?

Dual-Mode Detection: See & Hear

Don't just guess where a signal is coming from. Pair the unit with headphones to simultaneously visualise emissions on the display and listen to the audio output. This dual-mode capability allows for precise signal tracing and rapid source identification in complex environments.

Covert Threat Mitigation

Modern threats are often hidden in plain sight.
The Lockhart Ultrasonic is capable of:

  • Identifying unintended ultrasonic emissions from compromised electronics.
  • Detecting covert data exfiltration attempts via ultrasonic transmission channels (acoustic data leakage).

Intuitive Control Interface

Operators can customise their search parameters with:

  • Adjustable Signal Peak Analyser & Filter: Fine-tune sensitivity to isolate specific threats.
  • 3 Display Modes: Switch between Normal, Peak Hold, and Average modes to suit different detection scenarios.

Portable & Familiar Design

Weighing only 0.32kg, the Lockhart Ultrasonic features a familiar form factor that fits seamlessly into existing Lockhart workflows. It is lightweight, durable, and designed for one-handed operation during sweeps.

High Performance & All-Day Operations

Built for the field, this unit features a high-sensitivity receiver and an impressive 80dB dynamic range. With extended battery life (up to 40 hours), it is ready for long-duration sweeps without interruption.
