We have a set of Garmin 130 GNX's on the mast and a keypad with 4 options.
I assign:
1. Normal race mode
2. SOG & COG - for when things get sketchy with the compass or BSP log 
3. Start mode with a single display dedicated to Time to Gun
4. Round the cans racing mode with Time to Mark and splits on one display

Does anyone have any other ideas about how to setup the options for the keypad?
Cheers

What does having a 'mast height' calibration source file do to other parameters in EXP?
Should I have it, not have it, have a single figure or use a table that has mast height above the water associated with the heel of the boat (ie more heel, less height - geometric).
Not sure?

One supplementary question, the mast height value directly below the leeway cal
If I set this to actual wind instrument height, how does that affect 'everything'?
Does that affect the GRIB wind speed? I now have a boat with the wind instruments @ 32m above water level, so I am starting to consider the Hellemen exponent and would be factoring wind speed up by about 14%. Manual doesnt seem to talk about it?

In the Leeway calculation inside Expedition, if you check 'Leeway from heel and bsp' what coefficient is applied in the calculation of Leeway?

Nic - many thanks.
I actually have the same display states on both laptop - so that's OK.
So how do I export the settings? (I assume that will copy the Instrument connection details?)
