[QUOTE="KarlS, post: 110956, member: 2409"] Although chipped coils may lead to the monopoly and overcharging, from engeenring point of view they make lot of sense. The signal from receive part of the coil is very small and it has to travel another 6 or so feet, pass thru connector, picking along all sorts of EMI noises and then it is amplified (so is the noise) and processed in the control box. The chipped coils have preamplifier building into the coil and this design greatly improve signal to noise ratio. Karl [/QUOTE]
