The Slinger Bag itself does not oscillate. However, all of our Grand Slam Packs include an oscillator on which the Slinger Bag can sit and which allows the Slinger Bag to oscillate.
First, the SLINGER Bag needs to be placed on the oscillator and linked via the magnetic connector. Press "ON" for both the Launcher and Oscillator button on the remote control. The Oscillator will take 15 seconds to get powered up correctly before oscillation starts.

Please take care that the plastic lid on top of the cable from the Oscillator is removed before connecting with the launcher bag.

Yes. Slinger Bag has a remote control. The remote operates both the Launcher and the Oscillator "ON/OFF" from across the court.

No. It is for safety reasons that the Slinger Bag will only begin launching with a 2-step "ON" process (On switch "ON" first and then press "ON" on the remote to activate either the Launcher or the Launcher and the Oscillator).

Slinger Bag allows the user to modify ball speed, ball frequency and ball elevation independently.

The amount of topspin generated can be managed by altering the ball speed and elevation angle settings to find a launch sequence that works best for your game. SLINGER Bag is also easily moved on the court and we suggest testing varying court placements to find the best mix of placement, speed, angle and ball frequency for your level of play.

Yes, with the exception of Stage 3 Foam balls and any other kind of foam/shortex balls. After testing many different ball types we recommend using premium quality balls at all times in your Slinger Bag. We recommend and sell DUNLOP balls for an optimal performance.

On the top of your Slinger ball tube you will see 2 ball holder clips. To release the tennis balls simple push those two clips outwards to open the ball escape opening.

  1. Ensure that you have removed the plastic cover from the magnetic connector at the end of the cable.
  2. Ensure that the magnetic connector on both the end of the Oscillator cable and on the Launcher control panel are free from dirt / dust.
  3. Press "ON" for both the Launcher and Oscillator button on the remote control
  4. The Oscillator will take 15 seconds to get powered up correctly before oscillation starts.
  5. If, for any reason, these steps do not work, please contact our support team for further instance.

Please turn first “off” the oscilliator and the launcher before checking the inside of the Slinger bag. Please check the inside of the launcher bag. It could be the case that a ball was accidentally pushed between the turntable and the metal plate above it and blocks based on this the way for all balls to fall through to the turning wheel. So the Slinger bag is still running but no balls are launched anymore. You can easily remove the stuck ball during the machine is turned “off”. After turning the Slinger bag “on” again, balls will be launched again normally.
