I purchased a JACO Elite gauge for my ATV tires which was to be set at 4_1/2 psi front and 5 psi rear. The standard pressure gauge for my car does not accurately measure this low pressure. The JACO Elite measures in 1/10 psi increments and is very accurate and easy to use. I like the swivel head and the fact that the measurement is held so I can move to a lighted area to check the print. As soon as I see the result, I press the pressure release button and move on to the next tire. This is one of the best purchases I have ever made for my ATV. I would recommend it to anyone who needs a low pressure instrument.
