I went to the park a couple hours this morn and went over the totlot real good with the 6.5 x 9 coil I wanted to try it out as I was having problem pp with the large stock dd coil.
Well it was great didn't find a lot like 3 quarters, 2 nickels, 2 dimes and several pennies but the park is just right up the road and I hit it often so not to bad for a short hunt I didn't hit the open areas was kinda muddy after the rain.
I will be keeping the 6.5 x 9 coil on for all my coin hunting because pp is dead on with it every target I pp was right in the center.
I like the extra coverage of the 8.5 x 11 dd but I will keep it and use it if I go to the woods or areas I can use a shovel like for relic hunting.
As for depth I can't say yet I had the sen backed off 4 bars because I didn't want to go to deep due to the material under the wood chips but one of my coins was about 6 it was right on top of the material so it seems the depth might be ok with this coil too.
