Sorry it has taken so long , I should have waited a little bit before I started this "Surf P.I." thread ...... I am like a little kid , I get excited and want to share everything "RIGHT AWAY" with out using my head , before everything is ready !!! Idea

Hello , El Oro . To start , using this breadboard will be fine , it is only $3.49 at Radio-Shack . RS# is 276-158 or 276-170 . Then once you know that this Project works pretty good , you can experiment with a professional PCB circuit making Kit . Or just Keep the breadboard prototype you made and mount it in a Waterproof Plastic housing If you dive underwater !! Or a standard plastic housing for Land detecting . I need to make a parts list today and I will check Radio-Shack if they stock all the parts , Or I will tell you where you can purchase them. This is a Great working P.I. for learning and for building experience ...........Regards............Eugene52

Hello Everyone , Here is the Complete Parts List for this Great "Underwater P.I. " project !!! And yes this can work on Land Shocked

......Also resistors , capacitors and diodes bought in quantities are cheap !!! The I.C. chips are somewhere from 50 cents to $2. dollars each . Wire for the search coil is cheap . Use your imagination for the the search coil "FORM" and the Housing cover or "CIRCUIT CASE" ........This project is very inexpensive and a Great investment .......................Have a Great Day Everyone !!!!!!!!..................Regards............Eugene

Hello vpr2064 . Sorry I did not answer a previous post of yours on June 21 but I was 1300 miles away and no wireless signal on my laptop !! There should be no errors on the pcb . But the Schematic was the wrong P.I. , so I reposted it in 3 different places . This PI works very good .
Regards.......Eugene
