I have had my XT705 Gold Pack for a few weeks now and am going to have some time to hunt a few local parks here in Orange County / LA over the next week or so. I have used it out in the desert a few times using the stock 18.75 DD Coil with some success. I was lucky to pick up a 9" MF Concentric Coil on ebay for 60 bucks and was wondering if that would be better suited for parks than the 18.75 DD elliptical? Any other tips you X-Terra park hunters can provide? Happy Holidays!

Question about Park Hunting in SoCal w/ X-Terra 705

Since you have a DD and a concentric I would try both coils at the park and see which coil you seem to like the best. Your HF coil will be a lil better for the gold and nickels and your MF coil is good for all a round, nickels on up to silver.

It's my opinion to always start out with a HF coil first. They seem to react more quickly than the MF or LF coils. Get all of the easy stuff first with the HF coil and then use your MF or LF coil and slow things down a little and get the deep stuff.
In just about all cases I have found a decent number of coins after starting with a MF coil and retracing my steps with a HF coil. When starting with a HF coil and going back with a MF coil I've never found a notable amount of coins as I do using the opposite scenario.
Have fun!

A lot will depend on trash density. If it's not bad, then you'd probably like the 9" better. But if it's tough, the 5x10 will out do it.
Personally, I hate park hunting with an HF coil. It really doesn't give the response that I want for hunting in iron trash.

I second the trash density approach to coil selection.
Both coils achieve decent depth on coins.

The 5x10 HF coil is a coin hunters dream once you learn how to use it.
Thank you all for the great info. That was exactly the kind of stuff I was looking for. I think i will go ahead and start with the HF coil and see how it works and then move to the MF time permitting. I think we are going to start out at the park in the morning and hit the beach in the afternoon. I'll be sure to post my results after the hunt. Thanks again!
Hey Guys, I would say i had a fairly successful weekend getting to know my machine at a few local parks and a short time at the beach. At the local park, I found that the 9" MF Concentric coil really seemed to work well. I noticed that it had very stable TID numbers for coins, especially dimes and quarters. The HF Elliptical worked pretty good too, but it seemed like the TID jumped around quite a bit more. However, at the beach is where the HF DD Coil excelled. The high mineralization made it really tough for the concentric to do anything. Again, i appreciate all the help. I plan on working with the HF Coil at the park a little more as it seems like a lot of folks really like it for coin shooting (plus i think it will give me a better shot at some jewellry). I uploaded a picture of the finds for y'all to see. BTW, i found my first wheatie!
Looks like you're getting the hang of it!
Now it's just a matter of getting more time in on the machine. Learn from everything you dig.
HH!

Yep, you're getting there.
Newyearsday I headed out to my watering hole coin spot, very trashy.
Used the 6" DD HF coil, not run at max sens, few steps below that at 25.
Pulled a few coins, nothing really special, but fun. The HF coils appear to be a little chattery in the TID department because they have a faster reactivity.
They tend to signal high tone on flat ferrous surfaces, making them ideal for finding steel core coins and nickels.
Just switch from multi-tone to 4-tone and dig anything that has a persistent high-tone mixed in with the other audio.
You'll pull the odd crowncap, but you'll also pull a lot more coins from in between the trash.
Oh and don't think you need to cover a lot of ground.
I got about 10 coins and had moved only about 20 yds from the picnic table.
And talking about pulling stuff.
Well, up pulled one of those cartwheel large rims Mercs with 2 shiny exhausts.
2 dudes inside checking me out.
Drove into the muddy grassy patch and promptly got stuck.
"Hey Mister, could you give us a pull?!?!?" one of those youngsters yelled to that old fart weilding a razor sharp lesche digger and steel handled shovel with a edge gleaming in the early morning sunshine.
Shame it didn't fit into my finds pouch,.....

UPDATE: So, i went back to the park equipped with the HF Elliptical coil to give it another try. I do have to say that after spending some time with that coil, i see why a lot of folks prefer them to the concentric coils. I was able to separate the targets quite a bit better with the DD as compared to the concentrics. One thing I did notice with the HF coil is that the TID's were a little bit different than with the MF Concentric. For example, clad dimes were registering a 38 with the concentric MF...they were consistantly 40 with the HF coil. Only slightly different, but different nonetheless. The best thing I found on this last outing was a 1935 penny at about 8". Thanks again for the help!
Hi, glad your having fun ... 
What changed me from Conc to DD coils was a hunt for modern shallow coins with a friend
He had a DD on , I had the standard MF Concentric
I passed over a signal which sounded terrible / very scratchy and not like what we had been getting ( nice clear mid to high tone ...Australian modern coins)
My friend came along after me and seperated and picked out about 4 modern coins which were about 1 - 2" apart
When he asked me why I passed over that spot I explained what it happened.
We put the targets back down in the places where he dug them from and I unplugged my headphones so he could hear and swung the Conc. coil over them
he said " Oh , I see what you mean sounds crap ! I would have gone past a signal like that too".
I got him to to that with his DD coil so I could hear ...result was clear individual signals and TID numbers .
I went home put a DD coil and the Conc. now gathers dust.
Yes, as you have experienced....generally speaking Conc, coils are commonly known have the most accurate TID no's between the 2 coil types
It is a matter of preference though, DD or Conc. ..... some like one or the other , some use both types.

Now although a DD coil really separates well, there is a place for concentric coils whilst park hunting.
I look at DD versus Conc like this. Same coil size the DD is a flashlight on narrow beam, the Conc is a flashlight on normal beam.
When confronted with small surface trash, iron, foil, airgun rifle pellets, fishing shot, hunting shot,... and looking for larger targets deeper down.
I want to use my flashlight on normal beam, so part of the beam flows past the surface trash and illuminates the target below.
So now and again I will stick on the concentric trying to look past the surface trash and listen for those blended, but persistent high tones.
OK it's an earfull and TID will not read the "coin" numbers, but the detector will signal on targets you otherwise would have left behind.
It's all part of the detecting toolbox.
Ever wondered why most "basic coin shooting" machines have a Conc stuck on them straight out of the factory?

Great info. I have enjoyed hunting the park with both of the coils i have. I can spend almost all weekend there digging up coins, keys, trash and other stuff in a 100 sq ft area! The first day with the MF concentric and the next day with the HF DD. I found quite a bit with both of them. Now, if i only had a LF Coil too! I guess that is on the wishlist, but i think i have my work cut out for me at the 10 parks within a few miles of here with the coils i have first.
