ACE 250 Nel Tornado unstable

I just got this coil in the mail today and the detector goes off like crazy even when the whole unit is completely still at full sensitivity. I need to turn the sens down 2-3 notches just to have it not PING...Is this normal for these units?

The coil needs to be "tuned" to your control box. Your machine is ground balanced at the factory, so you can't ground balance it using an aftermarket coil. That is why you have to turn the sensitivity way down. I'm not even sure you can send it in to Garrett with an aftermarket coil to have it tuned. Call 'em.

Thanks for the advise...So after some further testing, it turns out that this coil is EXTREMELY sensitive to EMI...I was testing this in my house close to lights and all that, as soon as I took it outside it worked a LOT better. This coil is extremely sensitive...I really bought it for beach hunting to cover more ground faster and I think that really this coil would not be very good for more tight spaces...So overall I'm happy so far. I definitely see what you mean though by tuning.

I also want to put this coil (nel tornado) on for dry sand beach hunting (on my ace250)
For same reasons, large search, more coverage, depth
how is weight for 12x13?

would you recommend this or another coil?
