"The only 'spatial control' system that visualizes shot trajectories according to world standards."
The shots of the world's top players pass through a space of 60-90 cm above the net. However, many players only use the white net band (approximately 91 cm high) as a visual reference, resulting in a trajectory that is too low, or they slow down their swing speed out of fear of hitting the ball out.
The AccelZone provides a unique training space that simultaneously addresses the three elements of "high, fast, and deep" by installing a "second net" 180cm above the ground.
Features of the AccelZone
Another target above the net.
Shots from the world's top players pass 60-90cm above the net. The AccelZone aims to cultivate the physical sensation to automatically reproduce a "deep, heavy trajectory" that prevents the opponent from attacking, by setting up a virtual target line at a height of 180cm from the ground (approximately 90cm above the net).
1. Fully self-supporting, high-strength telescopic pole
It eliminates the instability often associated with existing products that require attachment to a net. Its uniquely designed self-standing base provides stability, making it resistant to tipping over even in strong winds or direct hits from balls.
2. Fixed 180cm height & adjustable height function
It can be quickly set to the golden standard of "180cm above the ground" for heavy balls. Fine-tuning between 120cm and 180cm is also easy to match to your practice level.
3. High visibility and high durability "Pro Code"
The rope features a special color that makes it resistant to breakage even when hit by the ball, allowing players to clearly visualize the ball's trajectory.
Recommended for people like you!
The AccelZone is used by players of various levels and positions.
Those whose shots tend to be shallow and who are easily attacked by their opponents.
For those who want to shift their mindset from "hitting just over the net" to "passing the rope over the arch," and achieve a natural depth.
Athletes who want to master a consistent spin ball.
For players who want to reduce net errors while hitting "heavy balls" that drop sharply near the baseline.
Coaches who want to create "standards" for instruction
For those who want to give students a clear standard, such as "Pass it over the rope," rather than an abstract instruction like "Higher!"
To strengthen the academy club
For workplaces that want to visualize world-leading standards and raise the overall shot quality across the entire organization.
How to use the AccelZone
- "Trajectory correction" in baseline rallies
Simply having the mindset of passing the ball over the rope will naturally create an upward swing path, resulting in both power and stability.
- Ensuring "hang time" during defensive practice
When cornered, practicing to hit the ball even higher than the rope helps you acquire a "defensive trajectory" that allows you to gain sufficient time to recover.
- Training in conjunction with accelerators
The accelerator accelerates the swing, and its output is controlled in the accelerator zone. The goal is a perfect fusion of power and probability.
User feedback
"The net feels lower now, and my mistakes have drastically decreased."
I realized how much I had been gambling with low trajectories up until now. Just by being mindful of the line, the ball goes deeper, and I can pin my opponents back.
- Top junior players in Japan
"The fact that it's freestanding is the best thing about it. You can instantly create a professional training environment anywhere on the court."
Unlike net-mounted systems, the poles are easy to move. Whether for ball-feeding practice or match simulations, a "standard" can be established in an instant, which has improved the efficiency of coaching.

Frequently Asked Questions
Won't it fall over in the wind?
Heavy-Ball Pro's unique pole-supporting design provides stability that prevents it from falling over due to outdoor winds or even if a ball hits the pole.
Does the installation take a long time?
Once you get the hang of it, you can set it up by yourself in 2-3 minutes. The pole can also be easily extended and retracted, so you won't waste valuable practice time.
Is it okay if the ball hits the rope?
Yes, it uses a rope that is flexible and durable to absorb impact. It is designed so that the pole is less likely to fall over even if a ball hits the rope.
