XLT vs M6 Filter question

[ShawnP]

I saw that the XLT has 4 filters and the M6 is a 2 filter machine, same as its big brother the MXT. What does more filters mean to the user? Better discrimination? Faster recover?

I will be buying a second detector come tax time and I am leaning toward the M6 just for ease of use, but I have swung a friends XLT and it did well, even though it was a bit on the heavy side compared to my F4.

Also if i decide to get a second coil when I buy is, the 4x6 dd or 5.3 round better for trashy areas or are they about the same.

Thanks any info will be great.

4-Filter types such as the XLT or XL Pro:

Great Info, just what I was looking for. I still have some time to decide, and the XLT does sound like it would provide more growing room than the M6. Thank you.

It certainly would !!

Most two and four filter machines have exactly the same number of filters but in two or four pole configeration.
Two 'filter' are easier/cheaper to manufacture.
'Four' filter have a sharper cut off rate between signals they do or don't allow through.
One thing to look for in newer machine designs is for analogical filters that reduce the masking effect of surrounding iron on a good target.

Though I love my XLT its quite a bit more expensive than the M6 (or MXT) and the stock coil is not great. You should be able to get more depth easier from say the MXT and though it really needs an elliptical to replace its stock coil would still be a cheaper option.

Hi, How does one find out if a machine has an analogical filter? Does the dfx have one? It is terrible at the masking effect.

Good question. XP were saying that their faster than average recovery speed enabled deeper targets near iron to be located but have now suggested that the new analogical (why not analog?) filter is partly responsible. I shouldn't blame the DFX as the XLT is as bad with the stock coil.
