I should post my thoughts on several of the Minelab detectors.
The Explorer series have been abandoned. The entire series were essentially revolutionary using the FBS technology. I've never swung one, so I can't attest to very much about them.
Etrac...... Danged thing was so heavy due to the ergonomics, my elbow was killing me within a half hour. I put a swingy thing on mine and it helped, but just added to the amount of clutter I was strapped to. And pricing remained pretty high considering the CTX was introduced. Because the electronics (control module) were attached into the rod, I don't know if anyone ever tried to convert it to a straight shaft. I've heard the Etrac will soon by abandoned by Minelab as well.
CTX is very expensive if purchased new - I picked mine up used for $1500, a thousand bucks off. Ergonomics on the CTX is very good such that I can swing it all day long. Most times I'm swinging the CTX I can't even make out what the screen is saying to me due to the glare. I'd try one of the screen covers if I thought it would actually do any good. However, I only look at the screen when I'm ready to dig anyway.
FBS itself? Of course, the CTX is now FBS2. I don't really notice any difference between the sounds of the Etrac versus the CTX. But I can say that as a sound guy, I still swing my Fisher 1260X when the mood hits me. There's an incredible difference in the richness of the sound. On the 1260X, I am so accustomed to it I'm able to discriminate out the targets based on sounds by themselves.
With FBS and FBS2, it's like the difference between a street musician and a philharmonic orchestra compared to the Fisher. With the Minelabs, if I had better hearing I do believe I'd be able to determine whether the target were round or misshapen. Sometimes on targets I feel like I can almost do that now.
FBS sends 28 frequencies into the ground and have a computer chip in the control housing. The difference between FBS and FBS2 were in the coil design. There is an additional computer chip in the FBS2 coils.... But you can't use coils from the FBS detectors, and the extra coils tend to be very expensive. Personally, I don't yet see the need for extra coils on mine - at least for now.
In addition to the CTX, last Fall I picked up an Excal II. I need to go out in the yard and use that some today when it warms up a little more. Had the CTX in the yard yesterday for an hour, temperature in the 40's, and the wind ran up my britches leg making it quite uncomfortable. But, back to the Excal, it's heavy and ergonomics sucks. So, after tax season is over I'm looking to modify that to a straight shaft.
The Excalibur uses BBS technology which sends 17 frequencies into the sand and soil, older technology at this point, but as I'm retired, when they come out with the next generation of technology I likely won't be able to afford it! That is unless I find plenty treasure with this old technology.
Since I first started detecting in the Spring of '81, I've owned probably 15 detectors, but 12 of them were from the early 80's. I'm sold on Minelab's technology, I can't help but be. But I'm still learning, reading, practicing, and will likely continue to do so for quite some time ahead to finally be able to get everything it's telling me. They are very very complex.
I've owned several models of Garrett, a couple Bounty Hunters, the White's 6000D, a Tesoro Royal Sabre, the Fisher 1260X, and then went into the Minelabs following a decade or so of absence from the hobby. The first detector when I came back was the Ace 250, and hunted beside a partner with the AT Pro. The Ace 250 convinced me to get rid of it after about the third frustration session with it - gave it to my brother, who then gave it back and I gave it to my cousin who's second signal was a 10k man's ring = I guess he likes it. I felt like I was confined to a box with that detector, silent black & white movies and I wanted technicolor with stereophonic sounds
And all along in my new return I kept reading posts about the Minelabs. I do not regret moving to Minelab. I view it as an evolution.
I do still love my Fisher 1260X though
