I am looking for a replacement 9 inch coil. I got a replacement last year that lasted a few months but now sadly it also has failed.

I might have one, I have a nice ADS 7, that I sent to Garrett's and had it gone over. They made it like new, I have 4 or 5 coils for it and a case. I have not used it for years, need to see what coils I do have. I will look and see if I have a 9" coil. Might take a day, going detecting today, might get to look tonight. I will post back here.

I think the coil is 7.5 that I am looking for.

Yeah, that was 'the amazing' thing about Garrett and the ADS 7 and almost all of it's early detectors from the '70's, they were 7.5" and looking back now, were too small for anything but park coin shooting...

I have a 12 inch that works on the ADS 7 but it is very very heavy. I hope I can find a good 7.5 for the ADS 7. This is the second 7.5 I have had that has failed by going open circuit...

That's the problem with the older Garrett coils, age deterioration. Some work better than others. You may have to go thru a number of them to find a hot one. Luckily you can usually find them cheap, or pick up a well used Garrett detector or non function detectors dirt cheap and hope it has a good coil. I remember the old coils also causing some drift if you start hunting at daylight, the sun comes out and outside temp starts to warm. Not generally a big issue, a quick threshold adjustment and you were fine. The 7.5" coils I thought were just the right size, probably why Minelab chose that size. For relic hunting or deep coin hunting we used the 10.5" coil but, you need the armrest. Funny thing Minelab also chose a 10.5" coil size.
