I took the Impact and my buddy took his CTX3030 to one of the toughest spots I know of yesterday for a hunt. We were blessed with perfect Northern Arizona weather up in the mixed conifers and well enough off of the beaten path that there were no holiday weekend "intruders".
The place is an old army fort that was established in the 1870s and then evolved in to a small town. You wouldn't know the place was ever there unless you had researched the old maps and then put boots on the ground and found the indicators like the old glass and square nails. The site is so trashy that the CTX in disc mode is silent on full arc swings due to the extended "null" on much of the ground. Mostly square nails of all sizes. The targets are not deep here... 4" being average. This site is a challenge for any machine or operator.
I put the small coil on the Impact, set it up in DI3, no disc, Iron Vol 3, TB to 26, gain 82, 20kHz, no tracking. The soil read three bars on the mineral scale and GBed at 81. Sounded like a machine gun of iron grunts. Yet, the Impact performed extremely well...the best of any machine I've had on this site. It's extremely fast and has laser like separation. Depth was not an issue out here as the targets had not sunk below about 4" due to a hard pack layer.
I recovered a couple of Spencer cases and a intact fired three ringer, .36 cal. pistol ball, fragments of lead, and some brass rivets. My buddy recovered just about the same. Nothing earth shattering. No bucket listers but a fun day nonetheless.
Observations about the Impact... Super fast recovery that lulled me in to thinking that I could swing faster than I should. When it hits on a good target in the sea of iron it hits hard, especially, mid tone targets. I never dug a good target that gave just a "one way" good tone. Most times, a good boot scrape changed that one way good tone helping the machine to "see it" better. It doesn't always hold true, but on this hunt, if the target couldn't be confirmed in at least two directions it was junk. DI3 is the bomb in thick iron! No disc, iron volume on 2 or 3 and just listen for the higher tones to break through.
I have never recovered a coin here. The usual relic stuff but never a coin. It's a total mystery as to why. Anyway, I'll quit rambling. HH
