Stay away from the nox, is not worth its money! To many things are not right with the detector, the nox or 705 is the same! Get a second hand xp Deus if you want a good detector. The orx is good ,but the Deus gives you more 😉 Check Crawford or Wiltshire detectors, if you lucky detecnicks😉
Still better as the nox,the hf coil is super.....pitty that is no 11inch on the market. With the right adjustments you will find small silver soon😉 Hf coil is absolutely stable on beach, also no problems to power lines and e'fences.
