Innova 5568 Pro Digital Timing Light with Storage Case

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.
