Professional 12V Gasoline Engine Timing Tool | Advance / Dwell / RPM / Voltage Tester

Powerful measurement capabilities for Voltage/RPM, Advance Angle, and Dwell Angle. Compatible with 12V gasoline engines (2-stroke & 4-stroke) for cars, boats, motorcycles, tractors, and more. Works with most ignition systems: DIS, conventional, electronic and computer-controlled systems (domestic and import). NOT suitable for diesel engines.
Fix rough idling and hard starting caused by incorrect timing. Advance Angle mode allows quick & accurate timing setup – more intelligent than conventional timing lights. Dual-screen design displays advance angle (0°-90°) and RPM (200-9,999) simultaneously for easy operation. Reduces repair costs and improves fuel economy.
Eliminate misfires and weak sparks with Dwell Angle mode (0°-90°). Prevents roadside breakdowns and protects ignition coils from burning out. Displays cylinder values and supports 2-12 cylinder engines. Voltage/RPM mode identifies ideal engine speed for timing advance tests.
Upgraded xenon flash light with 10x longer lifespan for precise timing in tight spaces. 9-16V battery testing with no extra tools needed. Durable impact-resistant ABS housing (excellent insulator). Lightweight 1.57lbs design reduces fatigue by 80%. 6-foot cable for safe, effortless operation.
Water gun-style ergonomic design for comfortable single-handed use. 2.6" LCD HD white backlit display for clear visibility in daylight, darkness, and multi-angle checks. Tested for extreme environments – reliable startup and operation in hot summers and cold winters.
