Designed for very serious course skiers and available on inboard ski boats only (Slalom, Trick, Jump & Wakeboard modes). Includes "All Buoy No Magnet Timing" feature. Those slalom skiers just looking for simplicity and a great pull should consider the Star Gazer Wake Edition S. Now featuring "No Mag Timing" (Displays Ball 3 & full course times) The second Generation GPS based Star Gazer Three Event System is now shipping. Designed primarily for the tournament course skier using an inboard ski boat, the Star Gazer Three Event with Version 8.0 software delivers the smoothest Slalom pull on the market and will amaze you with its ability to deliver actual or near actual times pass after pass. And speaking of timing, there is no longer a need to install magnets in your course as Star Gazer now features as standard the No Magnet Timing Method. You have the ability to enter up to three courses in the system's memory, so no matter when you ski any of these courses the timing feature is on automatic. In addition to the Slalom Mode (Including Practice mode) the system features our world-renowned Trick, Wakeboard and Jump Modes. Add a Z Box Serious tournament skiers that want to train at home on a boat that feels like a new boat with the ZO system can add the Z Box now or at any point in the future. The Star Gazer Three Event will easily install on most inboard powered ski boats manufactured over the last 20 years (MPI or carbureted engines and on newer DBW Engines up to 2008 model year)
