Velocitek created the Performance Sailing GPS Instrument product category in 2005. We have been designing, manufacturing and selling self-contained, race-specific GPS instruments longer than anyone else. We have kept in constant contact with our customers to study how Velocitek products are used in the heat of battle. The ProStart and SpeedPuck were both designed with a primary focus on providing a stress-free user experience. This is a direct result of the years we have spent observing professional sailors use our products. Observing our products in use has convinced us that, more important than offering any clever new feature, the most important thing an instrument can do to help you get better results is to never distract your crew from sailing the boat. If you try going through a start sequence with any other brand of instrument and then switch to a Velocitek, you will probably be shocked by the extent to which the stress-free Velocitek user experience impacts your crew's performance.
