It's White's 6000Di pro. Information for search coil you can find in US Pat No 4,293,816 & US pat No 4,862,316.

Thank you G. Georgiev!
I have look at one of patents and noticed that the coils are concentric (too hard for homemade). How you think - can I use DD coil instead?
BTW - my ICQ No is 169439945
