The ultimate in accuracy and repeatability! 

When it comes to choosing a leak checker, there are about as many choices as there are days in the year. If your looking for one to tell you when you have a dime sized hole in the top of your piston, just about any one out there will do. If your looking for one that will show a 0.1% variation between cylinders, we've got the one your looking for. Not only is it great for analyzing engine condition, you will be surprised at how many other places it will come in handy. Imagine how nice it would be to match your carburetor air bleeds within 0.1%, or be able to repeat a barrel valve setting within 0.1%.
