Been out with the Nexus MP and the new 24khz Concentric coil on,this coil is crazy light weight and was in my opinion a wise move,the Low freq coils are 'OK' for real deep pasture site work for say relic/hoard hunting but i personally much prefer a high khz coil like the new Concentrics,deadly on small hammered coins especially on trash sites.I use the Standard SE with the dual 9'' coil on for deep pasture use and the MP for roman and saxon sites,but my everyday use coil will always be the Deus and also have the new HF elliptical coil on order as well,one detector with 2 coils that covers the freq range from 4khz-70khz,such a versatile detector.
