If you want to navigate long distances and want yo use something for navigation only, I would certainly go For the Wahoo Elemnt or the Elemnt Bolt. If you want to use it for navigation plus points of interest, accomodation, gas stations etc. I would go for one of the garmin models.
There is a huge selection to choose from. It all depends on what your requirements are.
There is always paper maps as well. If I am touring I usually have a Garmin and paper maps. I have recently bought the Elemnt Bolt and it is brilliant. I will also have my mobile phone with me which is also useful for navigation.
I shouldnt get lost. But I probably will. Actually, I am never lost. But not necessarily on the route I want to be on.
