Thanks for the info Gary, your help is much appreciated.

I have retested as you mentioned with the threshold adjustment at the 11olock position the result was I started to pick up the EMI a little earlier. I have watched Doug Stones Videos a few times now and have learned quite a bit from them they are very informative. Thanks for your feedback you've...

I have just done the previous check again using 15x8 wss DD coil using the following settings : channel switch to both, threshold at about 7 o'clock, shallow deep switch to normal, tone to 11 olock, fixed tracking switch to tracking, disc switch to all metal, level switch to 11 olock . The...

The threshold tone was warbling very loudly when up close inside.

Thanks everybody for their assistance it is greatly appreciated as everybody suspected there is nothing wrong with the machine. I was advised last night to try a little experiment with it by starting it up and turning on my tv then approach it swinging the coil. I finally picked up some EMI at...

I have an unmodified SD2200D which possibly requires a repair due to the facts when going through the start procedure as per the manual holding the machine horizontally and swinging it through an arc of about 180 degrees it is not picking up any EMI before ground balancing. It is picking up...

Thanks Loamer for your time and details that you have given us newby's. I would possibly have never got the information that you have provided by just reading alone and would have probably not even given some of the work sites that you have described a second glance.Great work thanks again for...

I am currently building a Surf P.I. 1.2 MD and would like to use a coil lead plug connector which i can connect different types of manufactured coils. Do all coil manufacturers use similar plug connectors and which pins do they use. I have used a coil basically as designed by J.J.Rogowski...

:) Thanks for spending the time to write an extremely informative piece of information which will be a great guide to a lot of newbies entering into our hobby again thanks. Cheers Dave.m

Hi Mrlimb, I also am in the process of building a Surf P.I. 1.2 metal detector and have completed my coil using using the information I gathered off Geotech (coils) with a link to: How to build a high speed coil by B.B.Sailor I haven't tried it yet as I had a failure on my pcb, but there is a...

I'm a total newby to the forum and looking forward to sharing my limited experiences and gaining information from the members of the forum. I currently use a Gold Bug 2 and am presently constructing a Surf P.I 1.2 detector. I have completed the coil which is a 13 x 6 mono eliptical using...

:) I searched the net for quite a while and decided to buy a Gold Bug 2 based on what I had read on various forums only to be a little disapointed with the performance of the machine in mineralised ground and would say to anybody now to save a little longer and purchase a mid range pulse...
