Well I got my SE and did some hunting. Although I don't have enough time on the SE to give a good comparison to the DFX as far as a toe to toe, and I can give my first impressions.
Putting it together: It took all of 10 minutes to put it together out of the box. Everything seemed to fit good and tight and I had no problems with it(shaft) being loose as some had mentioned. Maybe in time it may change but at this point I'm very happy with it's construction. So ends my first concern.
Air Test: With the "factory settings" the air tests were just like the DFX. Same depth same signal strength. No surprises.
Test Garden: My test garden is about 2 years old and consists of 2 areas. Area 1 has a penny, nickle, dime and quarter at 4-5" and the other has the same at 7-8". The SE had no problems finding all targets from 4-5" but found none of the targets in the 7-8" garden. Not surprising since my test garden seems to have very bad ground. The SE performed pretty much as good as my DFX in the test garden. Strange as it may be the detectors that have preformed best in my test garden are Garrett's. In my test garden the ACE 250 did better than both my DFX and SE. I think the key here is being able to maintain a stable threshold. The SE would not maintain a stable threshold no matter how many times I noise canceled. The only time I had a threshold was when the coil was not in motion at all. The Garrett's seem to keep a solid threshold in any conditions.
First Hunt: We took the new SE to a new site which was a 3 block long area where the old building had been bulldozed. This was a big mistake, and I knew better, but my thoughts were I know enough about detectors to take a new detector anywhere. I was wrong when it comes to the SE. The tones were far too confusing as was the visual information in such a trashy site. I can say the SE is a beer can magnet. As my hunting buddies found possible good targets they would have me check them so I could better understand what my new detector was saying. All I could tell them was it sounded like a beer can. Most of these cans had been plowed into different sizes so they were all over my ID(Smartfind). Most of them read just like a penny. In all honesty I feel my DFX handles trashy areas such as this better. Mainly due to it's better visual ID'ing. With time this may change.
Second Hunt: I talked my buddies into going somewhere less challenging to test the SE. I needed a place where the trash was more predictable, and less abundant, and more coins were likely. We chose a school that we have hunted many times before with some luck. I found a 1903 Indian Head here with my DFX about a month ago. Things went much better. I could actually hear a threshold part of the time and was finally finding coins. At this site my understanding of the SE took a giant leap forward. Several times when my buddies had me check a signal I was actually able to give a better guess on the targets ID then they did. While I didn't find any old coins I was impressed with several finds. First was a signal that sound solid and my guess from the *cough* depth reading was 7". Roughly at this depth I dug a musket ball. The very next target, at roughly 6" was an old rim-fire 45 caliber shell like the ones we find at Fort Dodge. Makes me think this SE could be a relic monster.
Conclusion: I know I don't have enough time in the SE yet to make a full analysis, but I do think I can give a good "first time users" analysis. In my opinion the SE is not for the beginner unless an experienced SE users helps. I have no doubt the DFX is a more new user friendly detector. Pinpointing with the SE was right on the money as is the DFX. Depth was on par with the DFX, but the SE's *cough* depth meter leaves much to be desired. Actually I found the visual ID(SmartFind) pretty useless for the first time user. I saw no consistency in the visual information of the SE compared to the DFX. I hope in time this will change, but for the new user, visual information is far more useful than tone. As someone new to a detector I think the DFX wins hands-down when It comes to visual ID'ing. I now understand why SE users say it's all about learning the tone, because the visual information, at this point, is useless.
You hear people talk about the SE's weight as a problem. I can now say I know where they are coming from. After 4 hours of swing the SE both my arms are shot. Where the heck does all that weight come from? My DFX has 8 AA batteries and is built of metal but I can still swing it all day. The SE is built mostly of plastics but feels like swing a brick. After soaking my body in ointment last night I feel I will be able to do some more swing today, but my time is going to be limited this time around. I plan to take the SE to the best test site we have today where I plan to put the SE's "famed depth" to the test. I've cleaned this park with my DFX so now I'll see if the SE can pull the really deep stuff I know is still there.
All in all my first impression is the SE is on par as a top of the line detector. In time I'm sure I will understand the SE much better, but at this point I would say the DFX, for me, is the better detector. Now with that being said, the SE does show promise as a much better relic detector than my DFX. One thing I was a bit disappointed in was I saw a small 22 caliber shell on top the ground that the SE wouldn't pick up. I dig bunches of these with my DFX and they sound good and solid. I expected the SE to be more sensitive to these smaller targets.
Here is my take for the day:
