The Lobster Ultimate Remote Control offers the unique ability to create, edit, and save customized drills wirelessly (compatible with the Grand V, Grand V LE and Phenom 2 models only). This cutting edge remote control app not only commands every single feature on your Lobster tennis ball machine, but now you can create, alter, save or delete drills directly from your Android phone....no more programming the drills at the machine only. You can create up to six custom court drills with each drill having up to six sequential shots. Assign an independent ball speed, ball spin and ball feed rate for each and every shot within the custom court drill created. The options are endless!
