Leak down/Compression tester adapter?

What is everyone using to do a leak down or compression test? Neither of my tools has long enough threads to get down into the spark plug hole(is that the proper term--sounds funny?).

Most quality screw in compression testers have removable hoses that can be adapted to an air hose. Remove the schrader valve, screw the hose into the head, and pop the end on the air hose.

Found Proform 67400. Hopefully the threads are long enough.
