As mentioned, I have been enjoying the heck out the R2 with the small coil in my nail loaded cellar holes
The coil I'm using is the 4.5" OOR off my red racer Pro Pack, but I now have the round one from the R2 pro pack to see if there's any difference. After a week of rain, I was itching to get out. So, driving home from work & I'd remembered another trashy Colonial foundation I'd forgotten about along the highway. Again, it was considered "hunted out", but I had the R2 in my car & small coil on it & pulled over. Some people don't have the patience to listen to every nail like I do, but I love knowing what's below. Plus, rather than just getting one long low tone blur like my Garrett AT iron audios, I'm seeing every single square nail & watching each individual 04 flash on my LCD. I ran the unit right along the foundation itself where most guys won't even dare try to hunt. Heard that little squeek amid all the grunts & also a 60's ID show. I love finding military buttons & out popped my first engineers button from the Civil War era. I recognized the eagle w. banner motif right way & was happy to add a new military button to my display case thanks to the R2
