Innova 5568 Pro Digital Timing Light Tool with Digital Advance, LED Display, Ignition Timing for 2 and 4 Cycle Engines, Automotive Diagnostic Tool for Cars and Trucks

I previously had the Innova 3555 timing light and I have to say I was less than impressed with that particular model. It seemed prone to inaccurate induction readings and fluctuations at random times; it got to the point where I just couldn't trust it and actually had to use an older timing light from the 1970's to confirm its readings and/or errors. After doing some research and checking reviews here on Amazon, I decided to give Innova's 5568 Pro model a shot. All I can say is "Wow, I'm impressed". This digital model is super easy to use. The directions are a bit lacking and confusing, but once you fire it up, it's very intuitive and easy to use. I was pleasantly surprised by how understandable the functions were once I started using it on the motor. Induction works 100% right out of the gate; no problems whatsoever. The digital timing advance/retard function worked really nicely also; you can push the arrows and watch the timing mark move forward or back 1 degree at a time. Very steady readings. I also appreciate that you can read the RPM's directly from the unit. This saves me from having to attach other diagnostic equipment. It's also nice to be able to turn off the flashing light when it's not needed. All in all, really impressed. Very nice timing light and seems to be very accurate and well designed/made. If you are considering between this model and the lower priced models, all I can say is the extra money gets you into a whole different ball park of quality. I wish I had gone with this model straightaway.

The best Timing Light I have ever had. Works great, and has all the features I need. It is very well-made as well.

Great value for the money, very easy to use, the functionality works perfect, the brightness is easy to read … Worth every penny I paid for it …

Light is well packaged. The fact that it is adjustable makes it easy to get into hard to reach spots. Makes a setting timing advance very easy.

Two years old and problems… Timing jumps around a few degrees. My old sun pro timing light is rock steady on same engine so it is not mechanical. Screen goes blank after a few minutes of use. Have to unplug and plug back in to reset.

I just received this timing light . Seems to work well. I use it to tune the stock points based ignition on my 1960s automobiles. Nice unit with Timing Light, Variable Timing Delay, Tach, Dwell and Voltmeter etc. Comfortable to hold. No trigger like other timing guns but an on-off button. The button is in a natural position and the light flashing stays on (without having to hold a trigger) until you push the button again. Nice feature is concurrent display of timing light delay with rpm so you can check base timing, mechanical advance and vacuum advance vs rpm. Timing flashes seemed consistant and steady. Also has concurrent display of system battery voltage vs rpm to check charging voltage vs rpm. Includes a dwell meter so you do not have to connect a seperate piece of equipment to check the point setting. The unit has a detachable cable that includes Inductive Pickup, Coil Connection and +- battery connections. The clips are a good size to make connections to battery and coil. The inductive pickup has a plastic cover so need to be careful with hot exhaust. I recommend hooking the unit up exactly as the manufacturer specifies in the manual. The only manual that came with the unit is a quick start quide. A more complete manual is available on the Innova website. I will have to see how this unit holds up over time. Hopefully it will be reliable and last a long time. I have had my old timing light for 30+ years and it still works - but does not have the variable delay feature like this one. Note that I ordered the 5568 but the unit i received is marked 5568a so these comments apply to this version. I recommend this unit for anyone with points based ignition.

I have purchased this several months ago and I am just now writing my review. I had the test end get heated to the point where it melted and the gauge wasn't working properly since the piece that was melted has to be completely shut around the spark plug wire to give the correct data. I called them up and they were really helpful and sent me a replacement. They said they have had a few people say they melted and are making them more "rugged"... I'm glad they did because I am very careful with all of my tools and was shocked it got damaged when an engine does get over 600 degrees when timing within seconds. Since they handled the replacement without making it difficult and the product is so easy to use, I would say it is worth it.

To start off I own a dyno shop and using a timing light is the start of all my work. I would give it 5stars if the RPM worked properly. On 4cycle the rpm is much too high, on 2cycle the rpm is correct but ignition timing is way off if you change the gun from zero. I compared this to the normal inductance timing light, of course when the gun is set to 0 they match perfectly. All other functions are great and the light is bright.

Great build quality, very easy to use.

Macht was es soll. Viele Funktionen. Habe ich gebraucht um meinen V8 einzustellen. Glatte Kaufempfehlung.

Excelente calidad del producto, el diseño es agradable por la hergonomia y el movimiento que ayuda a apuntar la luz a necesidad, y es muy útil la función de que todo el tiempo la luz parpadea sin tener que aplastar algún botón.
