After a few proto types i am pretty pleased with the results: Air test can pick up a NZ $2 coin at 310mm, Small fine silver ring @ 250mm Penny at 310mm. The detector has no discrim and only basis functions: Sensitivity and volume, there is delay and offset which are on the PCB so no really ideal to adjust out in the feild. I hope to get out to some hot beach ground this weekend for a swing. All up the cost was $75;00 for the made up board and $ 15:00 for the coil with wire left to make a few more, on that note the OHMS are still not quite wright with the coil so might be able to get a bit more depth out of it with a better coil. Would be great to hear from any one that has had a go at coil making for this kit. Roll on summer Happy detedting Steve File Attachment(s): detector.jpg

So far I am more than happy with the unit, from some reading i have done they perform well on the beach. All up it will o me around $100, not bad for a PI machine. Cheers Seve

It lacks sensitivity big time to small targets, Am playing around with a few coils so might be able tweak it a bit more to get some more sensitivity out of it, Looking forward to to heading up the Waka so as it warms up a bit, Cheers Steve
