Hi everyone! Just a question out of curiosity: has anyone here used (or is anyone currently using) any kind of handheld satNav such as the Trekker Breeze? Just wondering as I've been toying with the idea of getting one for myself (it's one of the things on a list of possible treats I'm going to get for myself when I finish my thesis!), and was wondering if they're actually practical? As in, do they aid your sense of direction/orientation when using a cane? thanks a million for any responses! happy Friday to all, Christina
