Thank you for purchasing the Velocitek S5 GPS Race Computer!

The S5 can provide you with the following information:

•

Current speed in knots

•

Upwind and downwind velocity made good (VMG) in knots

•

Absolute maximum speed in knots

•

Fastest 10 second average speed in knots

Turning the S5 on for the first time

1. Open the waterproof case and turn on the S5 using the black plastic switch. Make sure that you are looking

at the LCD display when you activate the switch.

When you first activate the switch, the display will show a number between 0 and 99 for about 3 seconds.

This represents the amount of energy left in the device’s batteries. 99 represents fresh batteries and 0

represents dead ones.

2. The display will then switch to showing the letters “rE” for reset. Wait for 3 seconds and the display will

start flashing “00”

3. Place the device outdoors with a clear view of the sky for 15 minutes. This allows the device to download

the information it needs to operate from Global Positioning System (GPS) satellites. While the information

is being downloaded the display will blink “00”. After the initial download, this procedure only needs to

be repeated when the batteries are changed. This device will not work indoors, in built-up urban areas or

Kspeed.Com has stored the geographical coordinates of the two reference points and assumes that the wind direction is the same as the heading from the downwind point to the upwind point. These points only serve to tell the device the wind direction. They could be anywhere; on the beach, in the parki...

Optimizing vmg is far more important than just going fast. In an upwind/downwind race vmg is the “bottom line”. Plain speed is only important in the context of how it affects your vmg. For example, if you sail on a beam reach, perpendicular to the wind, you will go really fast but you won’t get any ...
