Tom Pouce 1,
Transition to version 2 and 3
I am a user of Tom Pouce 3 since November 2013.
At that time, I was already a regular Tom Pouce used since January 2009 with Tom Pouce 1.
I went to Tom Pouce 2 in 2011 until November 2013.
The Tom Pouce 3 is a very good device, it allows me to move more fluidly, I can avoid the obstacles in front, up to 10 meters.
A special feature of this device is that it can also detect obstacles in height, which the tip of the cane can not detect.
