In more recent yeas I have also used the 5¾", both sizes of Concentric design. In '83, and from then forward, I used a Tesoro that I trusted and most often with a 7" coil mounted. Iron, specifically nails, are my #1 foe when I hunt anywhere! Thirty years ago, in 1983, Tesoro introduced the Inca and it caught my attention immediately because it used a motion Discriminate mode (VLF-Disc.) to help ignore the ground signal, and the excellent slow-sweep (2-filter design) with quick-response and fast-recovery worked great in trashier sites, and it was very quiet in the ferrous-based trash. model in uneven ground, however, posed a challenge to try ad maintain a uniform coil-to-ground relationship. units are true-progressive Discriminators, and the higher frequency they operated at, ☑00 kHz, helped them just ignore many/most iron nails. Prior to 1983 the better detectors I had for working nail infested sites were some of the good TR-Disc. Monte: In past posts you've indicated that the IDX Pro and your Tesoros are your machines of choice for hunting in iron-infested locations.Let me break down number of favorites, over the past 30 years, for hunting in iron infested sites, especially those with a dense amount of iron nails. ![]()
