I have had a Whites DFX and a Garret ATPro for many years. I recently bought a Nox 900 and I am very disappointed. I tried it on a nearby beach where the DFX has had a modicum of success in the past few years and even the ATPro has done ok in the drier sand. We do have black sand here and I tried both beach 1 and 2 programs (large coil). The 900 kept throwing medium to high high vdi's and almost every target dug up was iron. I didn't find a single coin and only a couple of tab tops and yet I know there are a lot of both out there. My DFX would have blown the 900 away and the machine is about 23 years old. In the park I tried both field 1 and 2 in an area that we find Minnie balls in and same deal, almost every target within the lead range vdi's or higher was oxidized iron. I tried several higher iron bias settings with no appreciable improvement. The ATPro has found several hundred balls here even though it is subject to occasional iron falsing. Around several soccer fields where the other detectors have been stellar performers, I found about 10 coins hunting in the same general area with my brother with his ATPro. He found about 60 coins and a lot of trash. I didn't even find much trash. The machine gave a lot of iffy tone indications indications but few of the solid target hits like the ATPro or DFX. The 900 has got to be more capable than that. I bought from a reputable company and the warranty went through with no problem so no Chinese clone here. I have been using the basic factory programs with 5 tone and a little more iron bias in the bullet field and beach. Properly noise canceled and ground balanced. I am not new to detecting but am beginning to feel I got a lemon. My next move is to try the small coil in case the large is bad. Don't know what else to do! Next move is warranty! Any insight would be appreciated.
