I think i see your point 7688, but
Id say the rule did not mean to exclude the Micro with its bearing change, via compass bearing, or the added info from what i would say was the same thing but in another form. ie, Actual increments moved from a mean.
If I’m correct, the Master tells you how far or how long to the line and that is to much imfo over the brain working it out for me to accept and so would ask for that not to be allowed.
Unless your telling us that the Master needs say a gps input to get the time too, or the distance from the line.
If thats so, then the standard Master will be the same as the Micro in a more costly box. Some how i think it does more than that but i’m starting to need a GPS as im getting a bit lost???? 😕
