The Mini-guide is pretty complicated in terms of settings. I think I will eventually get it figured out but it will take a bit to work comfortably with it I think. I will love it for traffic I think. I have to go on a conversion site though as its based on the metric system and I want to be sure how far I set it for better than just an idea. Anyway it vibrates pulses. It does have an audio function but obviously I won't use that. The faster/ harder the vibrations the closer to you the item is. I have to try it outside though I think and it caustions against rain so I might not be able to use it too much for a while. I could use it in stores though which is one of my biggest issues as people just think the midst of the aisle right in front of me is where they will stop and congregate to catch up with each other... Anyway when I can get it figured out and know better how it can help me with Thane (down the road of course) I will share more. Karyn and Thane
