hi,

can anyone tell me in easy to understand terms if the numbers from a garmin GPS with bluechart can be used on a lowrance plotter using navionics gold charts??

do they use the same datum etc??

if not, is there some formula for conversion??

i was given numbers from a navman and they are about 0.1 of a mile out to the N/E on my lowrance as they use different datum, will it be the same with the garmin numbers??

thanks

You can change the datum on the plotter to match what ever the navman was using.
It will be in the gps setup somewhere.
It should then put you pretty much in the same position.
Normally the datum should be WGS84.
