The "buzz-box" magneto synchronizer is perhaps the most well known of its type. Its simple design makes it absolutely foolproof. Just attach the leads to the magneto, and adjust until you see the lights and hear the buzz!
This timing light is very well made and works as advertised. If I had any complaint, it would be that when I received it the battery was not wrapped in anything and banging around loose inside the device. Nothing was damaged, but could have been. Very poorly packaged.
excellent. It was out of stock when I ordered it and it arrived before the identified time. Great service!
When I opened the box, I heard a rattle. Upon opening the timing light box, I found one of the nuts that hold the board to the face was loose & not fastened. I fastened the nut, turned the unit on, and it appeared to work. I have not used it yet.
I have used this exact make and model timing instrument for over forty years and when leaking battery caused problems, i looked for and replaced it with the same E50 that has only changed their tone of alert as far as I can tell, all else is identical. I have every confidence that the new one will still be working when Im gone in another forty years or so.
Veru easy to use, just bought this item, and it works as advertised. Checked my Bendix mags on my IO-540 Lycoming and both were sycro'ed nearly perfectly after using the E50.
