 I have made some metal detectors, both VLF and PI. Until now, one of my favorite is the Minipulse Plus Beach as known as MPP Beach. It is a Pulse Induction detector specially designed to work in the beaches but you can tune it to use in many other situations, like finding Gold nuggets. If you are interested in the project, please check the Geotech Forums, in my opinio, the best forum about metal detectors:  https://www.geotech1.com/forums/forum/projects/minipulse-plus/14902-mpp-beach-rev-e Below, are 2 videos I have testing the detector I've build, firt, with a Spider web coil and latelly with a simple mono coil with 3m shield tape. https://youtube.com/shorts/ksGzeMP_x0I?si=OkjFHkC09U5LKZKO The best result was found using the mono loop coil shielded with the 3M tape. If you have already made this detector, please share in the comments your results with it!

 One of my favorite electronics projects are metal detectors. I'm trying to build some famous and more complex detectors like the TGSL (VLF) and the Delta Pulse (PI) but I also decided to try a very simple approach - using an Arduino and a few electronic components. As I also work with programming, it was very interesting to join the 2 areas (electronics and IT). The detector works as an "educational" purpose as it detects a large coin at about a 3-4 centimeters distance from the coil while professional detectors can detect objects at a very larger distance, although it can be a great opportunity to learn more about how metal detectors work (in this case using the Pulse Induction technology). I found this project in a YouTube video, and it is not created by me but I'm sharing it with you. In my test, I replaced the LED with a piezo buzzer, so, the components I used were: - 1x Arduino UNO - 1x protoboard (optional as you can mount the components any other way) - 2x 220...
