teknetics coil question.

[blugotti1]

hello guys! i have the tek.delta 4000 and it came with the round 8" coil. i was wandering if anyone has this detector or one of close likeness and has tried the oval 9x8 i think is the size coil on their machine and had any benefits of it? thanks all,David

I would like to see some tests with the delta and the non-standard coils available. Any links or videos out there. The ones i have seen are the 11"DD, 5"DD and 10" elliptical. I dont think the unit can give accurate depth over 10" when pin pointing so a bigger coil detecting at 13" will show as 10 on the LCD i think but i could be wrong.
