Product Description
The Perfect Pass Z Box is an upgrade for Stargazer 3 Event systems that delivers the feel and pull of a factory ZO system found in newer tournament ski boats. It's designed and tested for high-end short-line slalom skiing at 30 mph and above.
For tournament skiers running short-line passes on older inboard boats with Stargazer 3 Event installed, the Z Box transforms the boat's response and pull characteristics to closely match what ZO-equipped tournament boats feel like at speed.
**What you need to know before buying:**
- The Z Box is an upgrade module, not a standalone system. It requires an existing Stargazer 3 Event installed on your boat.
- If you currently run an older DigitalPro Perfect Pass system, you must first upgrade to Stargazer 3 Event before adding a Z Box.
- This upgrade is specifically tuned for tournament slalom skiing, not wakeboarding or general water sports.
**Who this is for:**
- Tournament slalom skiers running short-line passes
- Owners of older inboard ski boats who want ZO-style pull without buying a new boat
- Stargazer 3 Event customers who want to add tournament-grade performance to their existing system
**OnlyInboards Take:**
The Z Box is a niche upgrade. Most boat owners don't need it. But if you're a competitive slalom skier with an older boat and you want it to feel like a new ZO-equipped tournament boat at 30 mph and above, the Z Box is the only way to get that feel without replacing the boat. You can buy it with your Stargazer 3 Event at the time of purchase, or add it later when you decide to step up your training.
