- 05AstroAI
AstroAI Circuit Breaker Finder, Circuit Tracer Tool with GFCI Outlet Tester
Main highlights- [Precision Tracing Technique] - Maximize the accuracy of your circuit breaker finder by resetting the receiver away from the electrical panel to clear prior data, scanning each breaker slowly (for at least one second) near the wired terminals during the initial learning pass, and retracing the exact same path on the second pass to seamlessly isolate the correct breaker.
- [Instant Diagnostic Feedback] - The integrated outlet tester utilizes clear coding and multi-colored indicators to identify common wiring faults on the spot. It instantly highlights complex issues like open grounds, open neutrals, or reversed polarities by comparing illuminated lights against the printed diagnostic legend.
- [Dual-Sided LED GFCI Outlet Tester] - The transmitter doubles as a GFCI Outlet Tester with an automatic trip test function. Unlike traditional outlet testers that require referencing bottom light patterns, this upgraded transmitter features 3 LED indicators on both front and back, directly representing 8 wiring conditions. The dual-sided design eliminates blind spots caused by ground-up or ground-down outlets, ensuring clear visibility in any orientation.
- [All-in-One Functionality] - This device seamlessly integrates a circuit breaker finder, an outlet tester, and a GFCI tester into a single compact system. It allows users to safely verify wiring status, check ground-fault protection, and isolate specific breakers efficiently without needing multiple specialized tools.
- [Accurate and Reliable Tracing] - Utilizing a smart two-scan "learn and locate" process, this advanced breaker finder completely eliminates panel guesswork. The receiver memorizes the panel's signals during the first scan and then precisely pinpoints the correct breaker on the second pass using continuous audible beeps and distinct red visual indicators.

VDIAGTOOL V210 Wire Tracer Electrical Automotive Open & Short Finder Circuit Tester Circuit Breaker Finder Fault Probe Wire Tester Electrical DC 6-42V
Main highlights- 【SHORT CIRCUIT DETECTION】V210 car circuit tester allows you to find intermittent problems when bending wires or connectors and listening to the receiver tone change, without damaging the insulation layer.Receiver features adjustable sensitivity by knob and 7 inch flexible probe. Note: The sound signal of this broken wire detector may be affected by circuit spread, resistance, shielding and complexity. To improve accuracy, check the wiring step by step and complete the signals to locate the exact short circuit.
- 【OPEN CIRCUIT LOCATOR / SHORT CURRENT & WIRE TRACKER】VDIAGTOOL V210 automotive circuit tester, powered by 2 9V batteries, easily locates breakpoints, open connections, broken wires and current leaks by pitch change, even tracks wires without damaging insulation. It is a practical and efficient diagnostic tool for DIYers, electricians and technicians, which allows you to quickly and easily check cable continuity and diagnose breakpoints. Attention: The circuit breaker detection should be carried out along the direction of the wire from the “+” pole to the “-” pole. When the buzzing sound encounters the location of the short circuit, the sound will suddenly decrease or disappear.
- 【IMPORTANT TIPS】This electric wire tracker includes 2 9V batteries for receiver and transmitter. When the signal is not strong enough, the receiver volume will be low: find a stronger signal and adjust it to the maximum level. Check at the same time that the charging of the batteries is sufficient, as this affects the correct operation of the tool. When you do not use the V210 automotive circuit tester, please leave it in the OFF position or directly remove the batteries to avoid unnecessary power consumption.
- 【EFFECTIVE LOCATION OF INTERRUPTION POINTS】The V210 broken wire detector includes transmitter and receiver with LEDs that indicate open or short circuit status. The built-in buzzer of the signal receiver helps you immediately and easily locate open connections, broken wires, current leaks and even track wires. Note: The signal strength affects the volume. If the sound is weak, try to adjust the position of the probe to get a stronger signal and achieve accurate detection.
