I finally got a chance to compare my 4 1/2 x 7 Excel and my Sun ray 5

[digitrich]

In a pile of dirt half the size of a house that was the grounds of a 1846 fort and first home of the city, first Platte blah, blah, blah. I started with the 4 1/2 x 7 and there was too much trash for it. It falsed allot and had a really hard time with the iron nails. I used it for two hours and dug mostly trash, no coins. I thought maybe it was just too trashy and thought about giving up. Went to go pick my crew up at the job and dropped them off. I came back and put on the Sun ray five....The chatter was gone, it settled down real nice and I could separate my signals better, My SE also ID'd allot better, so I could tell the nails from other stuff. In an hour, I got about ten cool things, this pile was a pile of trash and it was thick. I found a two inch wide circular copper button with three holes in the center, I'm guessing 200 years old, a penny that was so corroded I barely could tell it was a coin, it had a quarter inch of rust on both sides in sheets sticking to it, looked like rusted iron except for a small portion of the rim showing. I am still amazed my SE picked it up as a penny because there was at least twice as much corroded rusty iron sticking to it, then the penny itself and the rusted iron was on both sides!! When I got it home I took some of the rust off with a screw driver, it was a wheat, the date is a 1922 or possibly 1923 with no mint mark, I hope it's a 22 but even if it is, I don't know how I'm ever gonna get it clean enough, maybe electrolysis. I also found a button that's two inches wide with I'm "guessing" a Spanish soldier on it, but it kind of looks Roman, a raised head shot with I believe a once cork background. I didn't find any coins other than the penny, but I'd trade 100 coins to find those buttons again tomorrow. I did find some other odds and ends, a pewter lock plate for a door, really decorated that I split in half when I mistakenly pulled it from the petrified wood it was stuck to. If it's trash your in, go to the five, the 4 1/2 x 7 was not any more stable or usable than my 8 inch Sun ray because of the trash, the 4 1/2 x 7 does get more depth then the Sun ray five because it's seven inches long but that doesn't work in dense trash and if I wasn't in dense trash, I'd go to my eight and get even more depth. I don't really see a notch between the eight and five so narrow that I would turn to the Excel 4 1/2 x 7, not that it's a bad coil, it's not, but if you have the five and the eight, you're probably not going to need the one in between. This particular pile had a gazillion clinkers in it because the pile was over an old train track. The three enormous iron spikes I got with the 4 1/2 x 7 my SE called silver kind of proved that. The Excel got better depth, but lousy separation compared to the Sun ray five, both of which I pretty much expected. expected. I'm going to post those two buttons when I get a chance, maybe someone knows what they are.

I have never experienced the 4.5 x 7 chattering or being unstable nor have I found the sunray to be. Is it possible you didn't noise cancel the same way as you did with the sunray? You said you left the site then came back. I have found the 4.5 x 7 to be one of the best coils for separation and handling iron. If this coil is unstable and you bought it new, I would consider calling Kellyco for a replacement.

I can run the Sen. at 32 all day long. The 4X7 seperates better and will go deeper then Joey or the 7.5 M/L coil. I can't run the Joey or 7.5 wide open at Sen 32. I keep the 4X7 on my SE 90% of the time. : : Later, Jerry aka Tinfoil

Yes more than once I noise canceled, and I hunted the same path with both coils and used the five second. The 4.5 x 7 wasn't unstable, it just was too big for the job, on a double d the hot line is the center line, the 4.5 x 7 has a seven inch hot line, the five inch two inches shorter, so it separates better. Now most people aren't going to hunt a pile of loose dirt with clinkers too often but if you were to get into trash that dense, you would want to use the smallest coil you could. This is pretty simple math here guys, work with it, you'll figure it out. The 4.5 x 7 works perfectly fine, I've used it several times now, just not as well as my 5 in dense trash. The math is the math is the math. I'm sure people have had good results with their 4.5 x 7, but if they weren't in dense trash they probably would have gotten the same results with an 8 and better depth, and if they were in dense trash they would have gotten better results with a shorter hot line five inch coil for separation, it's real simple, a smaller coil gets better separation between targets and trash, that's what happened. The larger coil (4.5 x 7) was receiving too many signals at once for me to even pick one out of the crowd to isolate and pinpoint, I put on the five and I could separate the targets and hear them individually with a longer pause between signals, sometimes even a thresh hold, which was a welcomed change, let me tell ya. But you go ahead and hunt your butt off with your oblong doohickey and I'll follow you all day with that five inch and cherry pick away, or put on an eight and pick up the targets that inch and a half deeper your leaving.

I think I know a 5 inch coil will do better in extreme trash then a 7 inch coil. I assumed your 4.5x7 coil was running unstable, with chattering and falsing alot, and thought it may be bad as there were a few bad ones out there. My mistake and sorry to make a suggestion. You obviously have all the answers. Of course your last sentence told me a lot about you.

Sorry ,I don't see that at all. If you talk about crappy soil, and iron infested soil , we got it in W.MA.. In the woods ,and around Old home sites and Cellar Holes I haven't found a coil that works better .I heard that there is a new 6"coil Made by Excelerator that just might blow it away , But I haven't tried it out yet .

The 4.5 X 7 ExCellerator is hands down the winner "overall" between the coils mentioned
Although, I can see digitrich point about smaller coils giving better seperation in target rich areas. But ... when hunting dirt piles I will actually use my shovel and throw a few scoops of dirt aside and then check the dirt with my X-1 probe ... other than that, I use the 4.5 x 7 ExCellerator.
Whatever works best .... it's all good

I agree to disagree. And this situation I ran into where the site seemed unhuntable, opened up when I used my five inch. It makes me think about all those previous sites I had that same, too trashy, couldn't get a thresh hold scenario and how much fun it's going to be to go back with the five. If I see something different that changes my mind, I'll let you know, but my 4.5 x 7 hasn't proved itself to me like my five has. Whatever works is always the best choice to use and maybe in a medium trashy area I might do better with the Excellerator, who knows.

works in the Iron trash and junk the way it does. I need Depth right along with the smallness of the coil. Everything Down here is very deep. Everything old and nice is 8"+ and I am dealing with Salt salinity in the soil here. The 4X7" works great on a salt water beach also.Whatever works for you might not work for me. When I make a post like a lot of us, we post what works for us. Now if I could run 32 Manual on the 7.5"M/L or the 5X10" Joey coil they would get the Comment of which one is deeper. As it is, the Joey gets better depth then the 7.5"M/L. The Joey is more sensitive then the 7.5". How ever I got a Platypus Coil that is a Piece of Crap when compared to the 10" stock coil. It barely beats the Joey coil. Just no comparison though when you are head to head against the 10" M/L coil. Everything is relative to my area and that is all anyone is saying here. I hunt on the worst Black Sand Beach you ever could hunt on when I go visit the Kids in Jacksonville FL. That little 4X7" works better then the 7.5M/L and the Joey. Can you guess why. I think you need to read more, Post more before you make a Smart A$$ Post like that. All of us Old Guys here poke fun at one another and there is nothing wrong with that. If you are going to Poke fun at someone do it in a nice way not a Smart A$$ way. I have never Posted one thing on these Forums ever to blow Smoke up Anyones Butt. You get my Drift.
