Minelab 9" Concentric Coils Identification ?

[XTerraman]

I have an older Minelab X-Terra 70 and three 9" concentric coils for it.
None of the three coils is marked with their KHz.
The only markings are codes that look like this "H 00639"
I can't find any reference for those H codes.
Does anyone have a clue on how to tell the 3, 7.5 and 18.75 KHz coils apart by those H codes ?

I found the answer in the X-Terra 705 manual on page 49.

H = High 18.75 KHz
M = Med 7.5
L = Low 3.0

Since the X-70 is discontinued. I couldn't find a manual online.

That link only shows the X-Terra 705. The X 70 is not listed. But, the coil info is the same.

Thanks for helping
