Bad coil on my MXT ???

[Dan(NM)]

As you can see in the video, this coil has no depth, correct tone ID or VDI. The coil hasn't been used outdoors, but, I was getting ready to sell the machine and decided to check the coil, glad I did.

I'm guessing it's a bad coil but the couple I've had go bad would overload with a high gain setting, the first one got worse after a couple hunts and I couldn't even get to the preset level without it overloading. If you were going to keep it I would say send it in to the White's in Oregon and if they can't repair it they usually offer you a new one way cheaper than you can buy a new one anywhere else. HH

I'm going to send the video to Whites and see what they think. The 6x10 coil ID's correctly with twice the depth.

Very odd. What's the voltage displayed on those batteries when you turn the machine on? Have you tried rewinding the coil to your machine to see if there is any change? You mentioned it's been put away/unused - Did it work before?

Good thought about the batteries that coil might take more power than the 6X10DD if it's on the edge of low, I know I change mine when it hits ten volts when first turned on. Couple reasons why is first I notice a loss in depth when it gets under 10 volts and second is it might show 10 volts when first turned on but drop lower real quick after a little power draw. HH

Same here. When the voltage displayed on power up is 10 or less, I replace. I've actually tested mine with the D2 coil and there is was no difference between 10, 11, and 12 volt, but as soon as I hit 9 or 8, depth suffers gradually. So rather than waiting for 10 to change to 9, I just replace after I notice 10 volts after a session or two.

What ever happened?
