Looking to buy a Snap-On coolant system pressure tester for future use. Snap-On offers an air-powered (P/N SVTS263A) and also a hand pump-style (P/N SVTS272A). $14 price difference.
I can't come up with any reasons for buying the air-powered version over the hand pump. I can use the hand pump version anywhere (e.g., going to a relative's home to troubleshoot a vehicle), whereas I'm limited to using the air-powered version at a home with an air compressor (which most of my relatives do not have).
What do others think? Any legitimate reason for buying the air-powered over the hand pump version?
