[Blindtlk] Echo Location as a Mobility Aid, World Access For The Blind?

[wogg le4]

Hi all

I have read some material on this online and wondered if people could give me:

1. Information on this organization?
2. Have you done this training? Was it effective? If so, how?
Especially interested in the views of adults.
3. Practicalities, costs etc.

I really would appreciate your views or if you yourself don't know
suggestions what other lists I could ask this on.
Thanks
