When using GPS speed on moving water it is recommended that you use the stream compensation

feature to give more accurate readings.

The inbuilt GPS module will record your courses. This data can be viewed in Google Earth

once uploaded to a Mac or PC.

To view your .GPX files in Google Earth you must first open the program and then use

File > Open.

On open water your course is generally accurate to 2-3 metres / 6-9 feet, but on narrow

rivers trees, bridges and buildings will affect the results.

When this is selected the unit will display a factor that reflects how much you are slowing

the boat each stroke. This is derived from the averaged boat decelerations measured over

each stroke.

Checks vary considerably depending on boat types and crew weights but they are a useful

way of evaluating technical changes, for comparing crews, and for seeing how consistent

a crew's technique is throughout a race. However, because of this inherent variation, it isn't

realistic to suggest what figures you should be aiming to achieve with a particular crew.

Note that your CoxOrb must be square to the boat, when looking from above, in order to give

accurate check readings.

Top Tip: Record average checks for set workouts and compare them over time.

Stream Compensation

Put CoxOrb in 'STOP' mode and have the blades square

in the water so that the boat is moving with the stream.

Press 'SPLIT/CLR' for 3 seconds.

The unit will show a flashing 'Str C' . It will then measure

the speed of the boat over 20 seconds, which will count

down on display. When this is complete the distance

the boat moved during the 20 second period will be

displayed briefly, in metres, so you can see that the

compensation process produced a sensible result.

Note that you will need to re-compensate each time you

turn the boat.

Setting Time of Day Clock

Put CoxOrb in 'STOP' mode and hold 'CLOCK' for 8

seconds.

'24hr' will flash and you can press the volume control

buttons to switch between 12 and 24-hour mode. After

3 seconds of inactivity the unit will select your chosen

format and switch to flashing the next data set. Hours,

minutes and the date can be set in the same way.

Note that in 12 hour mode A & P are displayed to

distinguish between AM and PM.
