Looks pretty interesting...I could not see any of the videos, and some of the pictures, the bobber looked cheap, but they are some nice fish...worth a try...i like the idea of the controll you have with it!
I think you have to steer via your rod like when setting a hook, I don't see the point tho. you can still get to the weed edges etc by casting on angles.
It looks like the fins hold the direction that it travels in and when you want to change direction, you flip it over. It looks like you can't order this product in Canada.
