Hi Monte , for the past ten years I have used a variety of detectors . Those being a deus 1 , Mxt pro , m-6 , Garrett gti 2500 , whites Idx sl and pro , vanquish 540 , nox , xlt , V3i , Tesoro bandido , Mohave , and a few others . Now I know that I didn’t master any of them because I usually get a feel for them by the way they sound , hit on targets , the tones , the weight and customer service and the available coils for them and if they don’t mesh with me than I’ll put them in storage or sell them . Shoot I even have a couple of two box detectors that I may never use . One being a tf -900 , another whites tm 808 and the Garrett treasure hound for my cx111 . My all time favorites have been the m-6 or Mxt pro . Followed by the deus and the vanquish . A few of the detectors mentioned above , I still have . Some are brand new in the box . Others I’ve sold . My favorite coil on all machines has been the 9x5 where available for what ever detectors I have at the time . I use the 9” coil on the deus 11 but I also have the 11” coil for it . I guess you can call me a detector junki or hoarder lol . I just like trying different detectors . Right now I also have a legend pro pack that I purchased from Kickindirt that is still new in the box . But right now I’m having fun with the deus 11 so maybe one of these days I might just pull out the legend and give it a spin or maybe not
