I am into tools as much as I am electronics, so just reading about the M-Spector by Milwaukee makes me want to run out and add this to my collection. Why would I need this?
Because it never hurts to have another set of eyes...especially eyes that can fit into a 3/4 inch hole and see around bends for up to 3 feet. I could have used this particular camera for some past projects rather than trying to feel my way around with a bent coat hanger.
Available here for $200.
