I just recently purchased a new t2 and I must say that I love this detector! I was just wondering if the sef coil is as good as they say it is. I also saw that they have 2 dif size sef coils and I would like to get one but dont know which would be the better choice for the kind of detecting I do! I mostly just do old parks and residental homes but I would also like to start hunting the corn fields and other spots! I used the 5in coil and I was really happy with it. I just wished it went a little deeper. I just didnt want to spend 200 bucks on a coil that wont do much more then the one that came with the T2. Any feedback would be greatly appreciated! Thank you!
