Instead of the standard coil, I recommend the DD24 model, especially for searching for small items and exploring in water. Although its range for large coins is slightly smaller than that of the DD28, I don't notice any difference with small objects. On the contrary – I think the DD24 stands out with better separation and more precise target indication. If you focus on small finds, it is definitely worth choosing this coil.
