The Deus is not a trashy park hunting machine period! Its depth meter is all but useless, its target ID accuracy blows at depths where the Minelabs are still accurate. It can't reject a rusty bottle cap to save its life. And even when you get an ID the higher the frequency the more all targets are crunched together in a blob so hard to know what you are digging, a bit deeper and its target ID is jumping +-3 numbers making even more difficult. So why do I swing a Deus in a trashy park? Because what choice do I have after the trashy parks have been picked clean with Minelabs for the past 16 plus years. The Deus improved target separation in medium to heavy trash and iron will hit on masked targets the Minelabs won't, those will be the targets that are still out there to dig for the most part.
Lets talk deep coin hunting, I once swung a 15 inch WOT coil for 2 straight years, Minelab Explorer. You won't be using a coil that size in a trashy park with any degree of success. Find the light trash areas of the park sure, but the medium to heavy trash and iron its not happening. Its an open area hunter where nails and trash are spread out so the coil is never over more than 1 or 2 targets at a time. Remember its not just the 15 inch diameter of the coil, it will pick up shallow trash several inches off the outside parameter of the coil, you need elbow room for deep coin hunting with a big coil.
Then consider your local site conditions. I used to hunt in NY with the 15 inch WOT coil, targets are deep there, real deep. The first settlement was in the 1600's. Here on the west coast in the Portland/Vancouver area targets are just not that deep. They have only been buried for half as long and the soil has a lot of clay and glacial round rocks in it which keep targets from sinking. So I could rig my gear for deep target hunting but are there really any coins down there to dig? Doubtful.
Then consider your local soil mineralization. In my area we have really nasty volcanic magnetic black sand here in our soil, even the Minelabs have difficulty getting depth in this stuff. I found a WWII brass button honey hole recently. The buttons are about 1 inch in diameter and have been only about 7-8 inches deep yet the signals are terrible. In NY soil the Minelab Se Pro would have smacked those hard, yet here the signal was so bad I almost didn't dig the first one. It was about 1/2 coin, 1/4 mineralization, and 1/4 rusty iron even though no rusty iron was down there, that's the soil mineralization. I have dug 4 of them the past two days, all the same poor signal. Last night I switched from the 11 inch coil to the Minelab 8 inch coil thinking that might help with the soil mineralization...wrong! Even my 1 inch X1 probe can't deal with the mineralization the whole hole sounds like iron. So for deep hunting with big coils, its going to gobble that much more soil mineralization so that's something to consider before heading down that path.
Finally lets say you have some sites that lend themselves to deep coin hunting with big coils and there are some targets down there. Yes the Minelabs will give you better target ID at depth but it has its limits. I hunt DEEP with my Minelab Se Pro. Most people stop at a depth where the Minelabs are still giving decent target ID's, go deeper and at those depths target ID even on the Minelabs is out the window, similar to the Deus when it quits even guessing at an ID. Then its tones and target behavior as you sweep it from different angles. The tones will be a mix of soil, iron, and coin. Those brass buttons I dug yesterday from some angles were 70% iron tones, only giving me some coin/brass tones on 1 swing out of 3 or so. From other angles more coin/brass tones than iron. Really tried to imitate a rusty nail falsing.
But I'm watching the target behavior, does the targets location stay putt when sweeping from other angles or does the target seem to move to a new location, that's one trick to avoiding rusty nails falsing. The buttons stayed put as I circled them sweeping. When I get a bounce of an ID on the target did it land near a coin/brass location. I'm looking at an average, sweep it 10 or 20 times, out of the total how frequently is it trying to ID near a coin/brass ID.
Even deeper and even those techniques fail. Lets call it super deep, barely enough of a signal to just upset the coils balance and produce a smidgeon of a signal that disrupts the threshold. A false will do that, but falses don't repeat in the same location that's a target. I know not what the target is, but I know a target is there. Does the target mostly stay out of the rusty iron area of the screen, if so a good chance its not iron. But beyond that I don't have much target information. I once got a signal this bad on a NJ beach, when the Se Pro would even guess at a target ID on some swings, like the Deus at super depths even the Minelabs stop guessing at target ID, you sweep the target, hear it in the headphones but the cursor/target ID doesn't change. But on the swings where it did change, it was way down just above and to the right of nickel. The target was...wait for it...a pit of 40 giant silver Spanish 8 reale coins. Once I found the original signal my hunting partner and I dug a hole about 2 foot deep with shovels, then I stuck my coil down in the hole and it was screaming silver.
Anyway before you go spending a lot of money on a CTX give careful thought to your local site conditions, would hate for you to spend that kind of money and be disappointed. If others are hunting with the CTX in your area and making finds with them that would be encouraging.
