In open, clean ground — yes. A larger coil generates a wider and deeper electromagnetic field that reaches targets a smaller coil would miss. The practical limit is the signal-to-noise ratio in the ground conditions you hunt: in clean, moderately mineralized soil, a large coil adds meaningful depth. In heavily mineralized or trash-dense ground, the larger coil produces more ground noise and blended signals that can reduce effective performance despite the theoretical depth advantage. Match coil size to the site conditions.
