I can't speak for Kellyco - I don't work there.
The DFX, MXT etc coils may or may not work on the V if they are not V nulled. If they have really good nulls, they can work. If they don't, you can still use them, but you will lose some depth because the loop null is affecting the signals - it won't fry the machine obviously. The V is much more sensitive than the other machines. The coils that are now produced have the tighter nulls to work with the V's. They work just fine with the DFX, MXT's...
If you want to buy non - White's coils (we don't make them, so have no control if they are V-nulled or not), try one from your dealer out first and see how well it does. It may work just fine for what you want to do. But, it may be that if you buy one without trying it, you might have to run single freq 2.5k or 7.5k to get it to work. We don't recommend using a non-V coil on a V, but it's your decision whether you want to buy the 3rd party coil or not. As you see from other posts, they can work well for some people.
