ES 328 EZ Tach Plus Digital Tachometer 0–20,000 RPM — Wireless & Inductive Pickup, Backlit LCD

The ES 328 EZ Tach Plus is a portable digital tachometer that measures engine speed from 0 to 20,000 RPM using either a wireless pickup or an inductive clip.

Designed for mechanics, small-engine technicians, and DIYers, this compact handheld meter reads engine revolutions per minute for 2- and 4-cycle engines and supports 1–8 cylinder configurations. Its backlit LCD and built-in LED flashlight make it useful in dim engine bays, and the unit accepts a 9V battery for true field portability. The combination of a wide RPM range, dual pickup options, and rugged construction helps you get reliable speed readings on motorcycles, outboards, snowmobiles, lawn equipment, generators, ATVs, and light automotive work.

How accurate and versatile is the ES 328 EZ Tach Plus?

The tachometer offers high-resolution RPM readings with an accuracy cited around ±10 RPM, which is suitable for tuning, idle adjustments, and general diagnostics. It supports both 2-cycle and 4-cycle engines and can handle single- through eight-cylinder configurations, making it applicable across a broad set of small-engine and automotive uses.

• RPM range: 0 to 20,000 RPM for low-idle to high-revving engines
• Engine support: 2-cycle and 4-cycle engines, 1–8 cylinders
• Accuracy: approximately ±10 RPM for precise adjustments
• Use cases: motorcycles, outboards, snowmobiles, generators, lawn equipment, ATVs, automotive

What pickup methods does this tachometer use and when should I use each?

The ES 328 EZ Tach Plus provides two methods to detect engine speed: a wireless (optical or magnetic) pickup and an inductive clamp that attaches to the spark plug wire. Use the wireless pickup when you need non-contact readings or when access to ignition wiring is difficult; use the inductive clip for a direct, reliable signal from the ignition lead, especially in noisy electrical environments.

• Wireless pickup: convenient non-contact measurements and quick setup
• Inductive clip: clamps to spark plug wires for secure, interference-resistant readings
• Switching methods: allows flexibility across engine types and service scenarios

How does the display and lighting help during inspections?

The backlit LCD gives a clear numeric readout even in low light, and the integrated LED flashlight lights dark engine compartments for better visibility while positioning the probe or clip. These features reduce the need for a separate inspection light and speed up diagnostics in dim or cramped spaces.

• Backlit LCD: bright, easy-to-read numbers in low-light conditions
• Built-in LED flashlight: illuminates engine compartments for setup and observation
• Portable operation: powered by a single 9V battery for field use without external power

Is the unit durable enough for shop and field use?

The handheld design is built for portability and to withstand vibration typical of high-performance small engines. Lightweight and compact, it’s meant to be carried to remote sites or kept on the tool bench, offering dependable readings without bulky fixtures or power supplies.

• Handheld format: compact and easy to carry between jobs
• Battery-powered: 9V operation keeps it independent of vehicle power
• Designed for vibration: reliable readings on running engines and high-rev environments

Who is this for? The ES 328 EZ Tach Plus is aimed at technicians, mobile mechanics, and hobbyists who need a practical, accurate RPM meter for a wide range of small engines and light automotive tasks. If you tune motorcycles, maintain lawn and garden equipment, service outboards or ATVs, or perform basic automotive diagnostics, this tachometer supplies flexible pickup options, a wide RPM span, and convenient lighting to make field and shop measurements quicker and more reliable.
