Innova 5568 Pro Digital Timing Light with Storage Case - Shop-Grade

In this review the Innova 5568 Pro Digital Timing Light is evaluated as a shop-capable timing tool for mechanics and serious DIYers. The bottom line: it is built for daily use and offers a clear advantage over basic lights because of its four-function digital readout that combines tachometer, advance, dwell and voltage in one portable unit. The durable ABS housing, molded boot and detachable 6-ft leads make it convenient to use around engines, while the slim rotating barrel and backlit screen improve visibility when setting timing.

Key Features

• Four-function digital readout: Combines tachometer, advance degrees, dwell and voltage so users can read multiple parameters without switching tools.
• Wide tachometer range: Measures from about 249 to 9,990 RPM which covers most passenger vehicles and light trucks for timing and diagnostics.
• Patented skip circuitry: Maintains accurate triggering up to 9,990 RPM so readings remain stable on high-revving engines.
• Heavy-duty, shock proof housing: ABS construction and a molded boot protect the unit from drops and fan blades in workshop environments.
• Detachable 6-ft leads and inductive pickup: Provide flexible reach and one-hand operation while staying clear of moving components.
• Compact storage case: Molded plastic case keeps the timing light and leads organized for transport and shop storage.

Who It's For

The Innova 5568 Pro is best for professional technicians and serious home mechanics who want a reliable timing light with expanded diagnostic readouts beyond a basic strobe. Its rugged housing and backlit screen make it practical for everyday shop use and working in low light.

It may be more tool than needed for someone who only infrequently checks timing on a single older vehicle, and buyers who need vehicle-specific adapters for unusual ignition systems should verify compatibility, since the unit is designed for most DIS, conventional, electronic and computer-controlled systems.

Pros & Cons

Pros

• Solid build quality with a molded boot that protects the unit around fan blades.
• Multi-function display gives tachometer, advance, dwell and voltage without extra tools.
• Detachable 6-ft leads and inductive pickup enable flexible, one-hand operation.
• Backlit screen and rotating barrel improve visibility and aiming at timing marks.

Cons

• Some users report the advance function can be intermittent on certain engines, so double-check readings when making final adjustments.
• While universal fit is advertised, very early or highly specialized ignition systems may need alternative adapters or methods.
