Pinpointing comparison questions

[Anonymous]

Could some of you old timers tell me if you feel that the Sunray X-12 is easier to pinpoint with than the stock 10.5" coil, or visa versa?
The outer edge of the X-12 appears a lot narrower than the stock coil, and I also wonder if that makes the outside edge a little LESS sensitive to targets. Every illustration I've seen so far shows the sensitive area only down the center of a DD coil, but I've noticed that I pick up targets on the outside edge too. This seems to make target location and pinpointing a little more difficult, at least for me. Noticed it on the Sovereign coils, and now with the Explorer.
Any thoughts or suggestions would be appreciated.

Fred;
I have had great luck pinpointing with the X-12
I use the x method (90 degree passes).
can pinpoint to a 2x2 area most times
very deep coins 10-12 inches sometimes are in the side of the hole.
Try to ratchet in on the signal. ie. if you start with the pinpoint and get a broad signal, go back out of pinpoint and start with the coil nearer to the signal until you get a pinpoint signal that is only about 2 inches wide then rotate the coil on its center point 90 degrees to maintain the signal. The target will then be in the 2x2 area under the center of the coil. If the signal fades when the 90 degree turn is made then slowly move the coil left and right until the tone is back and then rotate back 90 degrees till you can maintain the tone during the turn.
My Brother-in-law is hunting with a Whites XLT with a concentric coil that are know for the accuracy of pinpointing and he is amazed how accuratly the large coil will pinpoint.
We have been hunting a site where we are digging a coin every 3 min. so am not wasting any time pinpointing. <IMG SRC="/forums/images/biggrin.gif" BORDER=0 ALT="">

Fred,
I get same results. Targets cause signals at outside edge of coil and on both sides of the center web, if they are close to coil. That is why surface coins can be a bitch to pinpoint at first, you can have 4 hits per sweep on one target. Center will hit much deeper so lifting coil and rescan to eliminate edge hits will let you find target.
Think this is inherent in all DD coils. Although x-12 is thinner in appearence than other coils not sure that the coil windings are actually smaller, maybe one of the people that have dissassembled or X-rayed coils can tell us. According to Charles(NY) there is very little margin for error as to coil windings and placement of windings. Not sure if manufacturers have a whole lot of leeway in making coils that have markedly different performance in pinpointing and other characteristics than others.

Would this pinpointing also apply to the 10 1/2"

Jim;
Good to see your post. Welcome to the forum and the ranks of Explorer users. Yes the same advice holds for the stock coil. surface coins can be tough to start, but when you get a multiple beep in pinpointing mode you will know you have a surface target. you can then either raise the coil or if you have a handheld pinpointer or an X-1 you can use that to locate it quickly.

center and turn good method I don't missem now....
