|A 10X magnifier of the highest optical quality with excellent resolution and perfect illumination. This type of tool can be used for the inspection of spark plugs. Ideal for machinists, toolmakers, etc. Requires two "C" batteries (not included). 1 lbs (0.5Kg) shipping weight.|
Meh... Itâ€™s kinda okay but not really worth the money and doesnâ€™t help viewing the deeper parts of the spark plugs. I really think youâ€™re better off with a magnifying lens on a visor and a flashlight.
When I clean my spark plugs, it takes extra effort to clean the little lead balls out from the base to the electrode deep into the dark area of the spark plug. I had hoped this illuminator would improve my view of this area. It does not improve viewing at all. The price is expensive but at least Aircraft Spruce let me return it.
