Your Signature below your post shows you had 7 detectors, including 2 of one model. By the 'sold' indication you're down to 3, with 2 of them being the same model. trust me when I tell you I have bought, sold, traded, and therefore owned and used an unimaginable list of detectors over the past 5½ decades and, like most folks with multiple units, I try to settle on those that provide me the best features and performance for the different applications that challenge me. Sites differ, ground mineral conditions differ, and the trash type and amount of trash to deal with will differ. Not all coins are 12" deep, and to be honest, in all these years I seldom encounter many coins that are deeper than an honest 9" depth. A good 90% or more of all the older coins I have found are in the surface to 4" depth range. Most 3" or less and a few on occasion down to 5". Site selection is part of the key.
I have learned a lot about detector selection going back to late '71 when I started keeping a personal outfit of 2 to 4 detectors on-hand that there is no 'perfect;' detector. I takes time to learn and master each make and model that seems to 'fit' some of the needs we have. The same goes for search coil selection to get the most out of a detector based upon the site conditions. Having more than one or two detectors gives us useful benefits to choose from based upon where we are hunting. But it take enough time to learn the strengths and weaknesses of any detector, even a new "entry level" unit.
As you can see below in my Signature, I currently have settled on a terrific set of detectors in my Regular-Use Detector Outfit that will work great for both my rural/remote Relic Hunting, which I mainly engage in, as well as the typical urban Coin & Jewelry Hunting. Most of my places abound in very dense ferrous target contamination you have to deal with in order to find the available keepers and unmask those that are somewhat masked by the trash. Not all detectors can do that, and othesr are only fair when things get really tough. But even some of the simpler or lower-priced detectors can still provide surprising performance in a lot of common junk or provide other strengths not shared by more expensive detectors.
Note that I have added the Simplex[sup]+[/sup] to my list, even though it hasn't arrived yet, and that is because I know the company's build quality and dedication to the consumers.to provide a quality product. It's simple yet well featured, and waterproof which I have a use for. I know, too, that the Simplex[sup]+[/sup] is going to provide very useful in-the-field performance for most of the places I'll grab it out of the vehicle .... but I also know that as good as it might be, I don't expect it to match or out-perform my Nokta CoRe or Relic in very dense nail and other iron trash [size=small](partly because it needs a smaller coil like 5" to handle the conditions)[/size], nor will it be a detector to out-perform my Tesoro in a tot-lot playground with a lot of metal structures [size=small](again, it at least needs a smaller size coil to work close to the metal structures)[/size]. There is no doubt in my mind that the Simplex[sup]+[/sup] is easily going to out-class all of the oither entry-level detectors in a price class from $200 to $500 with a comparable coil. And once Nokta / Makro get one or two accessory coils out for it, I know it will make a great detector for many hobbyists who are not overly active and can only afford one detector, or possibly two.
I am sure the detectors you are retaining satisfy some of your needs for the places you like to hunt, just as I am sure those I have in my Outfit have proven theirselves over time ... and the Simplex[sup]+[/sup] is going to be a welcome addition. But I also know I don't need to make a snap decision on if it is a fit or not based on a short comparison with a different model that is 3-times its retail price. I also think there will be one or two smaller-size coils out for this model in the near future. Not everything is deep, and that's especially true for so many places people regularly hunt here in the US or up north in Canada. We take on more littered parks or homesteads or ghost towns or public places that have building rubble and such than many of the foreign countries where most of the time is spent walking back-and-forth in harvested pasture land.
Imagine the versatility and usefulness of the Simplex[sup]+[/sup] if it also had something along the lines of a 5" DD or 7" Concentric coil to complement the standard 11" DD? I've owned and tried several of the newer models over the last few years in some really tough iron nail tests and challenging sites and they do not match my Nokta CoRe or Relic, even with their smallest size coil. Some of them are OK detectors for many uses, but have their weaknesses. And most of the lower-end offerings, from any other detector maker, have been close to pathetic for what they are asking as an MSRP. This new model from Nokta / Makro is going to be a game-changer in several ways, and there is no doubt that those who use it enough are going to learn and appreciate the strong points of the Simplex[sup]+[/sup]. I'm hoping they will have accessory coils within the next few months for this new device, too.
Anyway, just my opinion that you, and a few others, might be a bit too hasty by making quick decisions and using a wrong detector for comparisons that is out of the class of the Simplex[sup]+[/sup] and parting with a great detector way too soon. Just my opinions of course, but ....
