The Tesoro Compadre was designed with the idea that less is more. This modest machine can do a lot of the same things that its bigger brothers can do. It works great for coin hunting, competition hunting and relic hunting, but it does it without any excess knobs. Switch on the detector and you're working in a silent search, motion all metal mode. The farther you turn the knob, the more discrimination you can bring to bear on those trashy sites. The Compadre now comes a a 5.75" or 8" round concentric coil. The Compadre has it all. One knob simplicity for the beginner and high gain circuitry and the famous ED-180 discrimination for the advanced user. If one detector can do all of this, maybe less is more.
