Howdy folks! I just wanted to share my latest experience with a pair of Nexus detectors that I picked up. I have been using the Credo for about a year and recently took delivery of Georgi's latest version of the Nexus Standard Mk2. Unfortunately, I'm not going to tear them apart and reverse engineer them (although that is what everyone would like me to do including myself). The Mk2 is an amazing machine and the Credo is no slouch either.
First off, the ground where I live is really difficult to detect in.. You would be hard pressed to dig any U.S. coins deeper than about 7" in my hard packed clay in disc mode, even though detectors can be ground balanced easily. I have been hunting a Spanish -American war camp (1898 - 1899) for almost 20 years. One area I had beat to death with White's, Tesoro's, a Shadow X5 and a Nautilus DMCiib, and a few hand made pulse detectors and have recovered maybe 500 relics or so over the years. I thought I would take Georgi's latest creation to an area that I knew was pretty worked out, just to test his claims.
Today, I hunted for about 3 hours in a small area, maybe 30 X 50 yds. Mercy alive!! I dug 19 more relics in that small area that I had pounded for years!! I have probably walked over more relics in that small area than I had previously recovered. Almost everything was at 8+ inches and my spade was too short to use my foot on for most of my recoveries. I even dug small brass relics that I thought that I would miss by not using the X5. The other amazing fact is that I did not dig a single piece of iron the entire hunt..
Now, this brings me to the point of this post - the method to making deeper recoveries. The Nexus Std MK2 is a high power (not high gain) device. Georgi claims it uses a 140V P-P transmitter, approaching the power of a pulse machine, plus the coils are at resonance. I can attest to the fact that the depth comes at a price - Battery life. I might make it through one hunt with a set of alkaline "AA" batteries but they would probably get tossed at the end of the day. Rechargeable batteries are a must. One observation that I made is that the "OO" coil has an advantage over the 10" DD high energy coil by a long shot. Georgi was not kidding when he said that I would be disappointed if I did not go with the 9" "OO"s. As dumb as I might think that it looks, it's performance was awesome.
The trick for effective discrimination is that the LED bar can be used for discrimination and not the audio. Or.. a combination of dual tone, audio and LED bar can be used. I used very little discrimination but the LED bar would always hit solid BLUE for iron, RED or a combination of RED and BLUE for deep relics. I can understand why this detector has not made an entry into main stream marketing in the U.S. though. It just looks too unconventional. It also has a learning curve which I found to be a little harder than the Nautilus DMCiib, at least to coax the depth out of it, but once I figured it out I was very impressed.
Hope this rekindles some thought on these types of detectors.
