Dan, Sounds like you're saying 3030 and Nox are similar performers. They aren't similar in price though. Which leads me to the Deus2...I'd would hope it outperforms the Nox as its twice as much. Ive been saying this the past 4 yrs when people were comparing Deus1 and Nox...that they're in the same ballpark is amazing when price is considered...and many thought Deus1 wasn't in Nox's league!
When you compare the 800 with the CTX3030 there are easy to identify differences. I have owned both, Nox 800 3 years , my new CTX3030 about 45 days. Price is one, weight is another, quality of build is another and the CTX X-Y (FE-CO) color display with target trace is a huge difference.
But now lets ignore those and consider performance. All around all purpose use the Nox wins over the CTX. It is four very good detectors in one package. Being easily programmed to cherry pick silver coins, the CTX is the clear winner of the Nox 800. Ease of programming with the Xchange2 software is much better than the 800. Audio bins on the 800 can get confusing. It is crystal clear, drag and drop with the Xchange2 software.
Shaft issues, none on the CTX and the 800 feels cheap and wobbles. Internal wires in CTX shaft is so nice to be able to collapse the CTX with ease even with your hands full. Accurate depth gauge that reads in easy to under stand number of inches instead of bars, I love it. The 800 depth gauge was practically useless for me.
Quiet vs chatty, CTX wins hands down. Nox 800 being a hot machine reported on every minute speck of metal under the coil. Fine for beach hunters looking for micro jewelry on a clean ocean beach. Suck for people hunting coins and rings in a trashy park. To quiet the 800 down you had to lower the sensitivity and then you were hunting in the 4-5" trash range. Bottom line, the CTX is not for everyone, nor is the Nox 800 for everyone.
Relic hunting out in the country with little or no metallic trash, the 800 is a real winner. Same with in the desert away from modern trash, the 800 is a winner. It this is the type of hunting you do, then the nox 800 is the best value over the CTX.
The Mine lab pro swing harness is an answer to the weight problem. Not a perfect answer, but an answer that I can live with. I cannot swing the CTX strock coil for more than 30 min before my arm/wrist are tired.
95% of my hunting is trashy civil war sites for relics in urban Atlanta and Atlanta parks that also are very trashy. Hence my decision to sell my 800 and buy a CTX3030.
