So I have a question regarding the Dex Nav. I understand that as your search level for a pokemon gets higher, you start getting access to better goodies (such as higher chance for egg moves/high level/etc) but does leveling up the Search level also increase frequency of searching? The thing I've found the most annoying about the Dex Nav despite how cool it is it how uncommon it is that the search feature actually works. It seems like I can get it to work maybe once or twice per route before having to go back to town and back to "reset" the dex nav after hitting like 15 "there's nothing nearby" messages from the dex nav.
Edit: Nevermind, I've kind of figured it out after continuing to use the dex nav more. I see now that the better way to find a pokemon is to have their search page open, but then just run around by patches of grass and that pokemon will pop out. Muuuuuch better.
