I'm told that the 10" Solid White DD Coil from my Omega 8000 will work on ( and not damage) the Tek G2 !! But the Omega runs at 7.8 KHZ not at 19KHZ.......can these coils be compatible? Can a detector that runs at 19KHZ use the coils off of a 7.8KHZ unit??? Usually that is not the case...I'm thinking the 10" DD coil looks similar but there must be a 7.8KHZ version and a 19KHZ version.....any one know for sure?? . PS: Just tried a G2 for a weekend and....wow do I like it . Seems much better for my style of hunting than the Omega. While the Omega was good G2 .......will get me to cross over! That's why I'm asking about coil compatibility. Thanks for your replies.
