Yes, the Walker is in great shape. The biggest problem I see out there is people over tweak the machines and then they don't work as described. A machine can be over tweaked. 100 hours? Seriously? I must be doing something wrong. I TRUST my detectors. I look for relics 95% of the time. I don't have time for the beach anymore, I like the history not the dollar aspect and don't do parks, I just don't like them. I have certainly dug my share of everything.
Soooo...I also don't have a problem with iron. I do dig some, but face it, something like a silver half is going to scream at you. You dig it, no thought required. Almost all silver is that way. It just screams at you. Now some folded aluminum can mimic gold, one of my sites has the shredded beer cans it in, but I am correct 95% of the time it's aluminum before I dig it. Sometimes a part of an aluminum can down over a foot will engage my interest, you never know, but that's ok.
This last week I was at a Rev War and contact period American Indian site. Not one, no, not one coin signal in 295 acres! And no, I didn't grid all of that land. I found three hot spots and pulled out Indian artifacts (eyeballed), and some nice Indian trade materials, brass trade points, brass tinkle cones, Rev War bullets and a button. Here's the rub. I got this "nickel" signal. I could tell it wasn't deep, and I could tell it was small, but "learning" that kind of nuance doesn't take me long for some reason. My motto is "dig it all let God sort it out". I knew it wasn't iron. Pending further investigation, it is a very small nickel iron meteorite. I just was at the right place at the right time. The rock does test for nickel, so it's pretty definitive. 80' away I got a large iron signal, I knew it was iron, but I was hoping for a Rev War period ax. It was a Rev War American stirrup! I never dug one of those before and they're pretty expensive. It's being cleaned now.
I'm not sure if this applies to your situation but there are three things I'd like to emphasize 1) don't tweak the machine too much 2) if it's not there, you won't find it and 3) dig iffy signals. I don't dig nails unless I want to, sometimes I do to accurately date my site. Assuming your machine is in good operating order, it's a decent machine and should do the trick for you.
