Review: Good product - This is a good product.Has a nice long cord.The screen is easy to read.It's a good price, it's functionality works really easy.I like the carrying case that's a good value for the money and the connectivity is really easy
Review: Great product - For the price this probe is pretty damn good, I’ve used to test radiator fans, retract electronic parking brake motors, and a bunch of other stuff. If you aren’t trying to spend a thousand dollars on a Snap On or Matco power probe this is the probe to get.

## Features

- 【7-Mode Signal-Level Diagnostics】The KM50 automotive circuit tester packs seven diagnostic modes into one tool for the technician or DIYer who takes vehicle electrical work seriously: AC/DC voltage, resistance, diode, frequency, duty cycle, fuel injection testing, and component activation. Frequency and duty cycle modes read PWM signals and sensor outputs in real time. The dedicated fuel injector tester mode captures injector control pulses as they happen. A practical gift for the man who handles his own repairs across cars, trucks, RVs, trailers, and marine 8–30V systems
- 【Live Waveform Display on Color TFT Screen】The color TFT screen shows live signal waveforms instead of static numbers. Watch injector pulses, duty-cycle fluctuations, and voltage patterns unfold under actual operating conditions. Adjustable sampling rate and dual waveform-plus-digital views reveal unstable signals, dropouts, and intermittent behavior that static readings cannot capture. The display remains readable in dark engine bays thanks to the built-in LED work light. A gift for men who want to see exactly what is happening under the hood
- 【Component Activation Tool Without Removal】Apply positive or negative current through the rocker switch to power up lights, fans, motors, relays, and injectors directly at the probe tip. Verify whether a component is faulty or miswired before ordering a replacement. No jumper leads, no panel removal, no disassembly required. The low-current activation design draws under 100 mA, suitable for sensitive modern vehicle circuits. A solid gift idea for father that saves time and money on unnecessary part swaps
- 【Auto-Reset Breaker with Visual LEDs and Buzzer Alerts】The built-in 10A auto-reset circuit breaker trips on overload and resets automatically within seconds. Low-current operation protects vehicle ECUs, sensors and airbag systems during testing. Visual LEDs and buzzer alerts indicate polarity, voltage, ground, and continuity status instantly. The anti-slip grip allows one-hand operation in confined spaces. A reliable gift for the DIYer who works on vehicles in tight engine bays and under dashboards
- 【40ft Total Reach with Professional Accessories】A 20ft main cable plus 20ft extension delivers 40ft of working range for long trucks, trailers, and RVs. The kit includes probe tip, ground lead, extension cable, battery clamp, and a protective EVA hard case. Impact-resistant ABS housing and heavy-duty cables withstand daily workshop use. Test voltage, signal, and component activation anywhere on the vehicle without repositioning the battery connection. A complete gift set that arrives ready to use out of the box
