Whites vintage coil question {?}

[pmo]

I acquired a whites 8 inch coil that might have been with a 5000 D GEB/ TR detector ( not sure )...The only info on the coil was a serial number...97386...Can I find out what the KHZ is with this number ?...Would this coil work with a 5000 D GEB/ TR detector....or possibly other detectors of a similar KHZ ?....Phil

Just put it on the detector and try it. It won,t hurt the detector or coil, if not for that detector it won,t work. If the pins fit the detector without forcing it. I have some old 6.5k coils and most will work on the 5000 and 6000 detectors. Good Luck let us know how it works for you.

The reason I raised the question is that some operators say that the original 5000 D GEB / TR operates at 5.5 khz and future GEB discriminate types operate at 6.59 khz...For my use the 6.59 would be useful with other detectors I have, as long as I use a proper adaptor cable...I was hoping the code number I gave would offer a clue to the operating khz of that particular coil...Phil

I suspect that they're the old 4B coils like the one shown below, left pic. Or it could be this one off of my old 6000/D, right pic.

Stamped on the left mounting tab of the coil, where the rod connects to it is the coil winding designation code. Examples; 6B, D5, G, B4 etc.....


D4 and D5 coils were used on the 6000/D and 6/DB detectors only!! These were available in 8 inch and 15 inch.


B4 and B5 coils were used on the 4/DB and 5000/D detectors only!! Available in 8 inch and 15 inch sizes.


6B coils were used on the "series 2

That serial # 97386 is just the zip code for White's Electronics.

II appreciate everyone`s help...If I had the detectors available ( GEB/TR or GEB Discriminator ) it would be a simple matter...At this time I don`t..I`ll just have to wait for an opportunity to test with the actual detectors...This situation does raise an interesting question, though....Is there some practical way to test metal detector coils to find their proper operating khz ?

 

[TC-NM]

I really don't know how you would test them unless you just plug 'em in. But be careful as "Flinstone" said in his above message about pins.

You could just give White's a call and tell them your situation. They're the experts!

Good Luck,

TC-NM...our information was helpful...There was a B5 stamped letter on the left ear, and probably used with the 5000 D GEB/ TR earlier Whites model...From research done I now know this operates at 5.5 khz...I guess II will have to contact each individual manufacturer for specific info on their coils...The problem that occurs is that if there are no specific marks on the coil itself you don`t know the operating khz...There are cable adaptors available allowing you to use Whites coils on other detectors....Phil
