1. i'm 5'1".
2. no, i've never tried using tadoma. however, i'd love to learn, but don't know who can teach me. i wish i could have learned it at my local deafblind center, but they don't teach tadoma as a communication method for db clients.
3. yes. i use a mowat sensor. i've had my mowat since 1995 and it still works perfectly. the day it stops working is the day i'm going to be REALLY disappointed because it's so much better than the miniguide. imo, the miniguide is too small and doesn't provide the same degree of tactile feedback as the mowat. i also had the opportunity to try a hand guide, but it was even worse than the miniguide. another thing i like about the mowat is that it has better range (i.e. coverage) than the miniguide and hand guide. the battery in the mowat also lasts longer since it uses a 9 volt.
