I am just about finished with a surf pi board. I was curious how many people have built a DIY detector and maybe hear some of the stories (good/bad) associated.
The surf PI is a nice kit. I populated the board and still haven't got around to doing the coil. Lot of DIY stuff out there for someone that has some electronics background. The Baracudda I haven't started on yet as am doing the Mini-pluse plus. Suggestion is to take your time and check every component before installing. Also build by sections. Get the voltage regulators up and running etc. before stuffing the other components for the oscillator, Rec preamp etc. What ya gotta watch out for is the changes that are made over the years to the PCBs and schematics so you have a good match up scheme to PCB.
