6112M vs. 6112B High-Range Detector

[UncaBuffalo]

The 6112B had a 'hash-mark' on the high-range detector line, because the detector wasn't centered.  I do not see such a mark on the 6112M...is the detector centered now?

(I'll start googling, but thought maybe someone knew off the top of their head...)

Thanks!

Okay, on page 33, they talk about 'preferential direction' and 'radial on marking grooves', so maybe it just looks different than I'm used to...I'll put on my reading glasses and stare a little harder at the marking grooves when I get back to work...

However, now I have a new concern:  Read the first paragraph on page 5.  It says the 6112M will auto-switch between detectors.  That's all well and good in a uniform field, but how do I use it on a point-source?  It seems like there would be a way to force it to be on a certain detector, so you knew that it was actually in a good geometry with your fuel-flea...?

I used one of these to play with some hot trash the other night...and they are worthless for midrange point sources.  If you try to get the low range detector on the point, it auto-scales to the high range...and back to the low range...and back to the high range...ad infinitum...

I love the audible feature, so will continue to use the 6112M, but it needs to be modified so the user can forcefeed it which detector to be on.  If I had needed a 'real' contact dose rate, I would have had to bail out & grab a 6112B.

Or a "real RO-2" - of course after you had gotten finger rings & multi-badge, etc., so you could get close enough!

Too many point sources in this trash...I needed something with a small detector to get a realistic contact dose rate...

My tried-and-true OLD RO2 was right there for the rest of the job!
