Innova 5568 Pro Digital Timing Light with Storage Case

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 instructions are poor but I figured out that the green lead goes to the ignition Coil negative. I love that it has a built in tachometer and dwell. Makes it easy to set total advance without guessing RPM's. Feature packed at a reasonable price. It's not industrial grade like my old Snap-On, this is primarily for the weekend warrior. Very happy with this product. Thank you

It works well and makes it easy to see timing marks. Be careful when attaching to the plug wire. As a vehicle is idling the inductive clamp slid down the wire and got a little toasted on the headers, but that’s my fault not the tools and even after it got toasted it still works just fine.

I've used this several times now. After figuring out the buttons it seems to work nicely. The instructions should be updated, as they do not cover all functions as they should. Once I figured it out, it works well. We will see how long it lasts. If it weren't for the lack of instructions to come with it, I would have given it 5 stars, you can download a more detailed set of "How to and follow these" I found out which made it better to use.

Works great for all types of engines! Love the RPM display in real time, so that Idle can be properly set before adjusting timing. Multiple tools all in one. The durable case is just an added bonus. I also really like that the leads unplug from the tool.

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 had high hopes for this timing light, it seemed to have all the functions I needed. It worked for less than 2 minutes and then the light became so dim it would not illuminate the timing mark even in the dark.Of course, it is beyond the Amazon return window since I didn't need it for the first month. First use it failed me.Reached out to Innova customer support and they have been slow to respond and have not provided any useful help up to now.Not recommended.Update 9/5/24 : Amazon stood behind the product even though the manufacturer would not. Day 7 still no response from the manufacturer. If you purchase this product do not expect support from the manufacturer.Updated 9/27/24: Innova finally reached out to me and sent a return label for the timing light, no explanation just a label. Too bad Amazon already took care of this 3 weeks ago.Innova support is bad.
