[QUOTE="user 12139, post: 490445, member: 12139"] thats an air test and useless if you ask me. Why, because when the target is on surface your not really exercising the coils ability to distinguish between ground noise and target response THROUGH that ground that the threshold is tuned against.. remember tuning for a stable threshold particularly in heavily mineralised ground impacts the ability to respond to target. A noisy coil and a quiet coil = one coil handles the ground better but can it then respond to the target? Bury your targets when testing if you want a true representation of a coils performance. A coils performance MUST take into account all parameters before accurate relevant results can be obtained. If this was not the case, then all coil manufactures would not use beta testers... they would simply air test in the workshop before releasing the coil to market - now would you want this, I would think not!
