non-magnetic mechanical stylus force gauge

Need to get myself the stylus force gauge and after reading what other people say decided to buy the simple Shure SFG-2 but then realized from one of the reviews on Amazon (as well as here) that it is still a magnetic one? Just curious - if Sure does know that this feature can cause problems why they wouldn't fix it or is there already another one from them which is non-magnetic? I looked at Ortofon as well but that one seems a little too simplistic with only limited number of scale grades. Since I have some MC carts the magnetism I guess can cause a problem, just wondering if this is correct? Appreciate the feedback.
Thank you
To Stanwal - saw one review here about the magnetic

On Audiogon some indicated that old ones were magnetic too

But on the good side I got a response an hour ago from Shure where they said the device is NOT magnetic.

Just looking for the simple mechanical one so that I don't care about batteries. I can't say if this is only me but in my case they fail always when you need them most :)

Thanks and Best Regards
Actually what Shure said was

"It could haven when the SFG is too close to a magnet for a while."

I didn't go into discussion with them over this one but IMHO if the metal (of other material) is NOT magnetic how can a close magnet influence? Does it make sense?
This is the official answer from Shure if interested

Copy / paste:
Q:Can the SFG-2 be used with moving coil cartridges, or only with moving magnet cartridges?
A:We only speak for Shure cartridges - all are moving magnet and work well with the SFG-2.

Q:It is my understanding that the magnets in moving coil cartridges are powerful enough to attract the stainless steel balance beam of the SFG-2 and produce incorrect readings.
A:This is feasible, though we have never tested the theory. Most phono cartridges use Mumetal for the cartridge body; MuMetal acts as a magnetic shield, thus shielding the internal mechanism from outside magnetic influence and vice versa.
FYI - Stainless steel has no, or very slight, magnetic properties.
As has been pointed out here for many years, that canned response from Shure contains more errors and false assumptions than facts.

As Tobes asked, why buy a cheaply made, inaccurate tool when for very little more money you can buy a decently made tool that's more reliable and more accurate?
Yes, Dougdeacon, I guess you are correct, it makes sense to look at digital ones.
Thank you
