[QUOTE="Goldpick, post: 343929, member: 1695"] The signal strength does tend to taper off towards both ends of the DD coils, though should still pick up on most targets along the whole length of the centre axis. Have a go at running your MXT in pinpoint mode with the SEF coil, and try a few methods shown in the video below. That should give you a good idea on how the SEF reacts, and where the strongest response from that coil will be. Not all DD coils are of the same construction or shape, so they may vary in response between brands/models. Either way, best method is to simply overlap your swings to ensure maximum depth and coverage, and efficient use of time. Here's video illustrating methods of pinpointing, and it also gives you a good idea on how that centre axis of the coil reacts to a target.
