Mantis II Stereo Stethoscope

Absolutely. MANTIS provides two simultaneous line-level stereo outputs: one can be used for onsite listening while the other connects to a compatible audio link or cellular transmitter. For example, MAXSUR can pair MANTIS with ShadowRelay through a USB-C external sound adapter to stream audio securely to authorized team members. The accelerometers remain connected to the MANTIS amplifier by their sensor leads, but the monitored audio can be carried wirelessly from that position. Contact the MAXSUR team and we will configure the complete kit around your mission.

MANTIS can work through nearly any rigid wall or material capable of carrying vibration, including common drywall, wood, brick and concrete construction. Dense materials such as brick and concrete can provide excellent vibration propagation when the sensor has good surface contact. Wall assemblies, air gaps, insulation, source distance and background vibration still affect results. For a demanding reference, watch the demonstration above: a MAXSUR team member recovers clear audio through a commercial firewall made with four sheets of 3/4-inch drywall plus insulation. Typical residential walls are generally less challenging.

Yes - and that is one of MANTIS's biggest advantages. The two accelerometers feed separate left and right channels, and each channel has its own balance control. With thoughtful sensor placement, stereo separation can help an operator judge the relative direction of speech or movement behind the surface instead of hearing only a single blended audio channel.

Yes. MANTIS is an excellent tactical tool for barricaded-subject, hostage and pre-entry operations, but the same vibration-sensing technology can also help rescue teams listen for people trapped beneath rubble after tornadoes, earthquakes, explosions or structural collapse. In those missions, it may provide another way to identify signs of life and focus rescue efforts when visual access is impossible. It should be used as one element of the team's complete search methodology.

With quality alkaline batteries, agencies can expect a published 80 to 90 hours of continuous operation from four AA cells. That is enough for several days of field use without specialized batteries or charging equipment. MAXSUR can also discuss external-power options when the deployment needs to run longer.

Yes. MANTIS includes two threaded spikes and a hammer adapter so the accelerometers can be secured quickly to suitable wood or metal surfaces for longer-term or concealed monitoring. For harder compatible materials, trained personnel can prepare an appropriate pilot hole before mounting. Installation must be authorized, structurally appropriate and performed without damaging the accelerometer or creating an unsafe condition.

Yes. The two 1/8-inch stereo line-level outputs operate simultaneously. One output can support local monitoring while the second feeds a compatible external recorder, radio audio link or cellular backhaul device. Recording equipment is not listed as part of the standard MANTIS kit, so MAXSUR can help select and configure the required hardware.

No. The standard MANTIS is a self-contained acoustic sensing and amplification system, not an RF transmitter or cellular device. That makes it useful for quiet onsite monitoring. When remote listening is required, one of its audio outputs can be connected to a compatible transmitter or secure cellular platform selected for the operation.

The basic controls are straightforward and can be learned quickly. Strong results come from understanding surface coupling, testing multiple contact points, balancing the two sensor channels and recognizing environmental vibration. MAXSUR can provide operational guidance and help agencies build MANTIS into tactical, surveillance or rescue procedures.

MANTIS is intended for authorized law-enforcement, government, public-safety, tactical and qualified rescue customers. MAXSUR will confirm purchaser eligibility, mission requirements, accessories and the final system configuration before sale.
