In clean or moderately contaminated ground, yes - a larger coil reaches deeper on good targets by exposing a wider electromagnetic field. On trash-heavy sites, the advantage reverses: a larger coil sees multiple targets simultaneously and produces confused signals, making target ID harder. Larger coils are the right choice for open clean ground where coverage and depth are the priority. Small coils are the right choice on dense sites where target separation is the challenge.
