especially in light of the explanation given in the edit.

The edit does indeed change things. If I was replying to the edited version rather than replying to the original version I would reply differently. But judging a reply because it does not apply to what is now a completely different comment is an error that I strongly discourage.

Almost all of the value of the advice comes from the two additional paragraphs. Even then I suggest it somewhat exaggerates the relative value of carrying a magnet. This distracts from the probably overall more valuable advice of doing an additional 15 minutes research when purchasing a GPS device in order to maximise reliability.

The edit came hot on the heels of the original comment. Based on comment timestamps it seemed likely that you'd read it.

Welcome to the joys of race conditions. Even when you click the edit button the instant after you comment, for all the time spent writing the additional paragraphs anyone who loads the recent comments page sees the original. Then, for all the time they spent replying to your comment---and sometimes even replying to other recent comments on the same page load---they are not notified of any changes to your comment. So if either the edit takes a long time or the reply takes time, synchronization errors will frequently occur.

I sometimes realize that a comment of mine needs elaboration, or perhaps needs to be tempered somewhat with substantial argument rather than mere dismissal. In those cases where I expect the difference between the edit and the original to matter I often use a work around. I copy the text of the original then delete it. I then write the new 'edited' version and submit it as a fresh comment. (Corollary: If I fail to take such precautions I blame only myself!)
