Lobster Elite Grand Four with Premium Charger & Remote

The Elite Grand Slam IV is the most advanced battery operated portable tennis ball machine in the world. The Grand Slam IV offers unrivaled full random triple oscillation. This revolutionary design allows the machine to throw balls throughout the entire spectrum of the court mixing up speed, spin, trajectory and oscillation. Triple oscillation allows the machine to oscillate both vertically and horizontally simultaneously, allowing for random shots. Furthermore, the Grand Slam IV is programmed to never throw the ball out of the court. This fully random technological advancement allows for the Grand Slam IV to realistically simulate true match play, a feature that is unsurpassed by any portable tennis ball machine on the market. The Grand Slam IV is also equipped with six pre-programmed six shot drills that simulates the most popular styles of play - grinder, all courter, and power baseliner. These incredible drills mix up speed, trajectory, and spin to prepare you to play against the world's elite! With the press of a button, you can now practice against the playing style of your choice.

In addition, the Grand Slam IV is equipped with the most extensive 2-Line function found today. With its three versatile positional settings; Narrow, Medium, and Wide, you can groove your forehand and backhand ground strokes or use it as a great way to warm up your shots. Random, variable depth in 2-Line varies the depth of the shot randomly (short, mid and deep) within the normal 2-Linedrills if selected. The user can select narrow, medium, wide 2-Line drills and if interested, select variable depth to keep things interesting.

Ideal for intermediate to advanced players as well as professional coaches.

A random feed option allows users to vary the rate or time interval between ball tosses. Mixing up the ball rate interval simulates match play and keeps players on their toes.

The Grand Slam IV is also equipped with the most revolutionary control panel and wireless remote control found today. The "Lexan" control panel utilizes "touch-buttons" instead of dials, knobs, and switches. It also has a digital LCD screen which allows you to view all menu selections and settings. For those players who consider themselves "technologically challenged", do not fear. The Grand Slam IV was developed to be incredibly user friendly and can be operated by even the youngest of players. For operation of the machine while "on the fly", the Grand Slam IV features the 20-function Grand Remote control as well as the Premium Charger. The state-of-the-art compact controller allows you to adjust most every function of the machine with just a push of a button. Enjoy instantaneous changes in functionality like; play/pause, oscillation sweep, fully random, 2-Line, speed, feed, spin, and much more.

    In-depth Review

    The Short Story: A great investment to dramatically improve your tennis game and fitness level with a machine that has implemented the right set of features and functions! Proud owner of an Elite Grand IV with 20 function remote and cover. The Long Story: I spent quite a bit of time evaluating whether or not to get a machine, and then which machine and from which manufacturer. At first inspection, the cost for any machine with the features I wanted was pricey. The initial sticker shock kind of held me back for a year or so until I finally realized what am I waiting for -- I love tennis and I want to become a better player! Then the decision was which machine from which manufacturer. After some back and forth emails to representatives from these companies and demoing some machines at local clubs, Lobster stood out above and beyond the rest. I went with the Elite Grand IV as this model seemed to have everything I wanted and has all the same mechanicals as the top-end Elite Grand V LE. In fact, you can upgrade the Grand IV to the Grand V LE with a new electronic panel if you want those extra features. The price to upgrade is not much different than the price between the machines so I figured this was the way to go to have the option down the road should I ever need it. I got the very useful 20 function remote and the top quality fabric/vinyl cover. I waited a few months after purchasing the machine in order to provide the most comprehensive and useful review possible.…
