Despite the SEFs size, it balanced well and compared with the the stock SlimLine coil the difference in weight is not that great. 1 lb 14 oz for the SEF and 1 lb. 5 oz for the SlimLine. One of the next things I noticed is that I am now able to run at a higher sensitivity setting than I could using the stock coil.
I received the coil one evening after work and only had a short time to hunt so I hit a part of my lawn that I know I've pounded with the SlimLine. The SEF did not disappoint as I pulled my first silver from the lawn since April the 12th. That's 14 lawn hunts later!
You have to understand that my house was built in the mid 1800s and so the lawn contains a ton of metal trash making it very difficult to pull out "Good" signals.
Very shortly after digging the dime we left for a trip to Alabama to visit my son and daughter in-law. This was a great time to test the SEF coil in beach environments. My first hunt was on a Gulf (saltwater) beach. I noticed that I could not raise my Sensitivity above 14 in the water and 20 on wet sand. This, however, did not hinder the recovery of many coins. Be prepared to dig, this thing goes deep! I was digging one target that I never could recover because of the size of my scoop and the water that started the sand caving into my pit.
The second test was on a brackish water beach of Mobile Bay. This time the SE allowed me to add 5 notches to the sensitivty over what I could near the Gulf's saltwater. I was able to hunt at 20 in water and 25 on the the wet sand. Although this is an 80 year old swim area, I did not recover any older coins. During both of these hunt I recovered a good amount of clad that was deep.
Of course, a good detectorist never rests. Even at my son's house I was out in the yard when not at the beach. I never thought I'd like a larger coil but I was very happy with the amount of ground I could cover and felt confident that I didn't miss much. I pulled $3.10 in clad from his lawn alone along with this decorative clasp, ring and token! The clasp has the initial S. V. R. on it. I'm not sure what it's from.
While swinging this coil, I noticed that it uses the Pin-Point Feature on the SE very well. I was pleasantly surprised to experience how well that works!
In summary, the 15 x 12 SEF coil balances well and doesn't weigh a lot. As opposed to the stock coil it allows my SE to run at a higher sensitivity, locks on to targets better and is more stable.
I am anxiously waiting for some farm fields to be cleared off so I can run the SEF where I ran the SlimLine last Fall. Be watching for more reports as I run this thing through it's paces now that I have returned from my trip!

The SEF coil continues to amaze me in regard to target lock on and depth. Whoever says it can't seperate deep targets in trashy areas need to give it another try! While using the 15 x 12 this evening (in my trashy lawn) I got a good signal that the SE was showing me at
around 10 - 11 inches on it's depth indicator. I dug and found this piece of small piece of lead. Wow!
Saturday, I decided to hunt a public park that is over the top of an old landfill. This would be a challenge for the separation abilities of the SEF coil. In the case of wide open areas like this park, I love the amount of ground I can take in. It enables the user to take in a lot of territory in a speedy fashion.
Whenever I swept over a coin, the signal I was receiving quickly took prominence over the rest of the background trash and watching the SE depth indicator I was able to get right on top of my desired targets. I was able to pull a good number of items even in this environment. I even managed a 1940 Wheat Penny. As I worked along, I received a bit of a different signal which I tested from multiple angles. Upon digging, I was rewarded with my first ever SE gold! A nice class ring that I am in the process of trying to return.
