I've seen repeated posts about adding the 10x12 coil to the Silver uMax and turning it into a depth demon.

But what about the 9x8? Has anyone used that? Impressions?

I only ask because I'm not sure about the weight the 10x12 would add and how cumbersome it would be to use.
 

i 've had the set up and in my experience the 12 x 10 coil worked very well on the silver the 9 x 8 no difference to speak of between that and the 8" donut but that 12 x 10 coil i swear added 3" to my silver on average but the disc seemed to not work as good also tried the 12 x 10 on the golden to and that was a no go no extra depth and changed the tone, never did try it on my deleon i had but on the silver on the prob
 

Good information. Thanks! :icon_thumleft:
 

I found air testing the 8" donut and the 8x9 spoked.
No difference in performance on the Silver.

I agree here, but the 9x8 sure is a breeze to pinpoint with (not that it's hard with the donut).
