If you are reading this, you have likely just unboxed one of the most reliable workhorses in the tennis industry: the Tennis Tutor Model 2 .

Whether you are a coach running drills for a high school team or a parent trying to help their junior player groove their forehand, the Model 2 is a game-changer. However, like any precision piece of equipment, it requires a bit of know-how to get the most out of it.

Freezing temperatures will kill a lead-acid battery instantly. The plastic casing is UV resistant, but the internal electronics hate humidity. Store the machine in a dry place, preferably with a cover over the hopper to keep out spiders and leaves. The Tennis Tutor Model 2 manual is surprisingly well-written for an industrial machine. It is not flashy, but it is logical.
