The Velocitek ProStart is the essential electronic tool for racing sailboats, small keelboats, and dinghy sailors. There are two primary modes this GPS based unit works to help out the competitive sailor.
a) Pre Start - using the boat and pin settings, a team can set the start line into the GPS. Then the clock is used as a countdown timer so the unit displays distance to the line and time to the start. That's all the info necessary for a great start!
b) During the race the unit displays speed and angle, so while racing the primary info needed for racing can be tracked. Angle is a great aid to figuring out wind shifts and speed can help mode the boat based on expected speeds at various amounts of wind.
