I especially like to have my 1/8 inch fiberglass rods for fishing attics, walls and t-bar ceilings, 12' and 20' length of steel ball chain and a rare earth magnet again for fishing walls and two sizes of Flex Bits for drilling into awkward locations.

Of course the usual cordless 18V tool kit with saw-z-all, Circ saw, Flashlight, and Cordless Drill and a couple extra batteries.
