The DK Sportbot from China is a machine that has many features an advanced player would be looking for whilst also being suitable for beginners. This means it should be attractive to players of all levels and is a great machine to help you improve your game and get it tuned before the upcoming tennis season. The DK Sportbot comes with a remote control, speeds of up to 140 kph, 160-ball capacity, two-line drill, horizontal and vertical variation (it can shoot to six different points on the court), topspin and backspin, all with the extra challenge of internal oscillation.
The Spinfire Pro 2 has long been our most popular ball machine and it’s not hard to understand why with a free remote control, two-line drill, horizontal, vertical and triple oscillation, a choice of internal battery, external battery or AC power, unmatched levels of spin and internal movement to always keep you guessing where the next ball will land.
The Pro 2 been leading the Australian market for 10 years and offers an excellent build quality. But, if you are looking for a machine with all the best advanced features and you are on a tighter budget, we are very confident the DK Sportbot will more than meet your expectations.

| Battery Can the machine be run off a battery? | ||
| Battery Life The min and max play time possible when using the battery. | 3-4 hours | 3-8 hours |
| Battery size | 28.5 A/h | 20 A/h |

| Remote Does the machine offer a remote control to allow easy settings adjustments from the other end of the court? Note, all remotes are different, including the number of buttons and functions each can supply, so look for a photo of the remote you are considering to understand its features. Also, Tennis Tutor in Australia does not offer a remote control, but this may be possible to purchase in other parts of the world. | ||
| 2 Line Drill This is a drill which shoots one ball to the forehand, followed by a ball to the backhand, and it repeats endlessly. It will keep you running from side to side until you can take it no longer. Some machines offer this in just WIDE and NARROW, while others offer WIDE, MEDIUM and NARROW for a bit more flexibility. It's also a great drill to use when two players are practising together with a ball machine, as it will alternate firing a ball between each player. | ||
| Optional Spare Battery A spare battery is great for coaches or those heavy users who don't always have time to charge their battery between sessions, or may want even more play time than the standard minimum that each machine can provide. | ||
| Heavy Duty Battery | ||
| Optional Storage Cover These are great for protecting your machine from dust and debris, but we do not recommend you leave them out on court. | ||
| Warranty This is the standard manufacturer's warranty. Some machines do have the option to upgrade their warranty to up to 5 years for an additional fee. | 2 Years | 2 Years (Optional 5 years) |
