Interesting...


Here a single arrow tends to designate a jump whether popular or not and double arrows ( on their own ) usually indicate a circuit closing jump.

I came across some double arrows today way at the back of the cave that were not related to a circuit, however the jump was hidden way up in the ceiling. I wondered if someone was trying to say there really is a jump there.... keep looking! I guess a Florida diver put them there

Anyway it got me thinking.

Pity we don't standardize this stuff.

Thanks for the answers!
