	XR71 Operation Help « on: January 10, 2009, 08:48:29 pm »

Hello Everyone , the Delta Pulse "P.I." which is also called the Sniffer/XR71 is an Excellent P.I. Metal Detector Project to build . The bugs NOW have been worked out of this design . I will posting the construction details of this later on . So here on this Thunting.com forum , I will post only two P.I projects , the Hammerhead and the Delta Pulse/XR71 and that's it . I will post ONLY Two "VLF" Metal Detector projects , [to be determined sometime next week] .... So I will post a total of "Four Metal Detector Project's" to choose from , it will be a good selection ...........Any other additional projects can be contributed or suggested By other Thunting.Com Members !!! ...........................Regards.............Eugene

Off and On for the next week , I will be working on the Price's of a Working Sniffer/XR71 , with an 11 inch mono coil , or an optional 3 foot PVC coil . Prices will not include the case , but will have an Analog meter for signal strength and / battery test , and also the search-coil connecting cable . So:

1. Working Circuit board with potentiometers and switches
2. Standard Search Coil 11 inch
3. 6 foot connecting cable
4. Optional 3 foot PVC search coil .

I am just working on numbers , figures and prices now , will post estimates later !!!

Electronic parts will be from a very reputable West Coast Distributor . I am not sure yet , If I will sell here on Thunting , or Geotech or ebay !!! I am just getting Bright Ideas now Idea

[idea]Also depends on Economy and who is interested . I think it may be a Hot seller on e-bay !!! If not , I will have a Ton of Extra Parts to build other things Wise
