A technique for finding the nearest match in a computer storage system is provided. A sensing arrangement of the steering tool detects its pitch and yaw orientations at a series of spaced apart positions along the bore, each position is characterized by a measured extension of the drill string. Two such coasters can be used with one straw, and in this case, both tabs are inserted together into the straw’s end. The first connector and the second connector are disposed on the circuit board. In another example, images of the point of interest taken from multiple locations may be used to determine the position of the point of interest.
