Steelman wireless chassis stethoscope kit — 4 transmitters, 50 ft range, receiver with speaker

The Steelman Wireless ChassisEAR is a four-transmitter wireless stethoscope kit that locates squeaks, rattles, and other vehicle noises up to 50 feet away.

Designed for mechanics and DIY enthusiasts, this kit turns a vehicle into an audible diagnostic field so you can find the origin of intermittent or hidden noises. Steelman’s 61082 system uses four independent transmitters that attach to engine bays, axles, suspension components or transmission housings and relay live sound to a receiver with an integrated speaker or headphone jack.

How does the kit find the exact source of a noise?

Each transmitter sends its own live audio channel to the receiver so you can isolate one area at a time. By switching channels, muting transmitters, and listening for changes while the vehicle is running or being moved, you can pinpoint which component is producing the sound.

• Four separate transmitters allow simultaneous monitoring of multiple locations.
• Channel selection and mute buttons identify which transmitter is active.
• LED signal strength indicators show relative transmitter volume and connectivity.
• Clips, magnets, and hook-and-loop straps let you secure transmitters to pipes, brackets, or housings.

Can I use the ChassisEAR on large vehicles or from a distance?

The transmitters communicate up to about 50 feet, making the set suitable for compact cars as well as many light trucks and larger vehicles. The range lets you listen while the vehicle is in normal operation or while someone moves parts to reproduce the issue.

• Approximately 50-foot transmitter-to-receiver range for flexible placement.
• Useful for under-hood inspections, wheel-end checks, and drivetrain diagnostics.
• Receiver includes a built-in speaker and a 3.5mm jack for private monitoring with headphones.

What accessories are included and how do they help during diagnostics?

The kit bundles a practical selection of mounting and listening accessories so you can start diagnosing immediately. Everything stores in a blow-molded case for tidy transport and organized workspace use.

• Four transmitters and one receiver for multi-point listening.
• Mini earphones for focused listening and four microphone clamp cable leads for contact pickup.
• Twelve nylon straps and twelve hook-and-loop straps plus built-in clips and magnets for secure placement.
• Batteries for both transmitter and receiver, organizer pouch, location note pad, and instruction manual included.

How do I interpret the receiver controls and indicators?

The receiver’s illuminated channel buttons and LEDs give clear visual feedback so you can work quickly in dim or busy environments. You can change channels, mute unwanted transmitters, and watch signal strength to determine which area is responsible for the noise.

• Illuminated channel buttons let you see active transmitters instantly.
• Mute buttons allow isolating a single source without removing transmitters.
• Signal strength LEDs help compare intensity between feed points while testing.

Who this kit is for: The Steelman Wireless ChassisEAR 61082 is built for professional technicians, shop owners, fleet mechanics and serious DIYers who need to locate intermittent or obscure automotive noises without running long audio cables. It’s ideal when noise only appears during driving or under load, when multiple components might be involved, or when a non-invasive, mobile listening solution speeds troubleshooting. Note: this model operates on different frequencies and is not compatible with older Steelman 60635 or 97202 units.
