I am interested in other cave divers interpretation of 2 arrows pointing the same way.
Could you let me know how you interpret this?

In Florida, it usually means there is a popular jump nearby.Quote:

Arrows are pointing out(supposedly) and it marks a popular jump.
Arrows are pointing to the nearest exit, and there is a possible jump in the area.
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!
YES it is a pity, it would be good aka safe, if cave markers were universal in their designation/meaning. Good post by the way.Quote:

I would identify it as a jump, where you tie in between the arrows, that are pointing out.
I agree, I would assume it marks a jump. But personally, I will put my own arrow on the line on the exit side of the double arrows, or if I am exiting against the arrows (for example at the Olsen to Crossover jump) I will place a cookie on the exit side of the arrows to avoid placing a conflicting line arrow and then tie off on my own arrow or cookie. I don't rely on markers other than my own.Quote:

The gap between the arrows indicates a precise location to tie off the jump line. The arrows continue to indicate the location of the exit. Of course the vast majority of my cave diving has been in the USA so its the system that I'm familiar with. I can see where it coud be confusing if its the complete opposite of the system you're used to. I do think its the more sensible method though. If there were an attempt to standardize a system my vote would be for that method -not that I'd get a vote :-)

In MX there are quite a few triple arrow jumps. 2 arrows pointing to the "closest" exit and one arrow pointing the other way towards an alternate exit.
----<--<-->-----
closest on left and alternate on right in this example.
I always reinforce my exit with a personal marker at jumps.
I find that very confusing, but work if you understand it I think, I'd rather use a BIG arow and not 2 arrows, but well
