what about the iphone gadgets ?
I have seen ads for two of them ... are there more? These two are shaped like bobbers
Fish Hunter sonar looks pretty slick
the black base on the ball is the charger unit, and its USB or mini usb I think
and the Deeper unit is Scandinavian and was featured on Kickstarter; there's more media about it
What do you know? Are there more of these? chime in if you know anything.
