Hi! I believe that one of the subscribers asked this morning, if I found a difference in sensitivity between the trekker and braille-note gps's. Ok here is what I did. Part of my walking routine takes me through an enclosure which houses different entrences to stores in a strip mall. It is not inside a building, but is the outside entrences facing a parking lot and there is a kind of decorative wall and a small roof overhead so you get a tunnel effect when you walk down this passage. My Delorme receiver on the Braille Note gps does not loose signal at all in this enclosure but the Trekker, I just found out in the last half hour does. Does anyone know if Radio Shack still sells the talking pedometer or will I have to go to a Blindness products supplier for such a device? I think I want one so I can utilize the trekker because I really like the weight and size of it. Mary Ellen Earls. P. S. I was going to go to a lovely park on our town square which is on an island in the middle of about 6 streets to see how the trekker's "free mode" operated but I brought in a zacada on my trekker strap and after I flushed him down the loo I decided being dive-bombed 3 different times in a space of 1 and a half minutes by these insipid animals was quite enough. I'll do it after the parade tomorrow. Bye for now. M. E.. E.
