Finally bit the bullet and ordered the 13" coil for my Omega. I don't need it for mineralized ground but was thinking the large coil size would be good for hunting the large soccer field near my house and maybe it would give me a little more depth. It finally quit raining long enough for me to get in a 2 1/2 hunt the other day in the grassy area people park on along the outside of the fence line that borders the field then moved across the road to one of the play areas at the shelter there. Not a fantastic day but then I have been hunting the play area on and off for a couple of years, ended the day with $1.32 2 quarters, 7 dimes and 12 pennies. Since I was cherry picking trying to get the hang of pin pointing with the coil the only trash targets I dug were bottle caps and I was fairly certain thats what a few of them where by the way the sound broke up at the edge of the target. Settings were gb at 61 sens at 68, disc maxed out and 4 tones just because I prefer the high sound and at times even with the disc maxed the mixed tones can indicate a trash target even though I get a good tid reading. As for the coil I like it so far, its light, easy to swing and surprisingly not that hard to learn to pinpoint with, tid numbers seem to be the same as the stock coil. Sorry for no pictures, the 2 working cameras I have on hand take to large a picture to post here and I don't know how to reduce it down. Hopefully I'll remember where my old point and shoot is and to buy some batteries for it and I'll get some pics of the detector and coil at least. Will be off work for the next to weeks so as long as the rain holds off I plan to get in a bunch more detecting with it.
