No - on both occasions it was the same scenario - descending from a peak in bad weather and picking the wrong ridge to descend - I was confident I "knew" which was the right ridge and with the app I use bearings for the right route are pretty difficult to distinguish - so completely my fault.

I'm now aware of that problem and haven't had that problem since but I was pretty shocked in retrospect that I confidently headed off in the wrong direction when the tool I was using was by any objective measure much better.

I agree with this:

"the key to navigating successfully is being able to read and understand a map and how it relates to your surroundings"
