Yes, I've been looking ,too.
I was going to get the CED2 from the LRH store.
Then I seen the acoustic one, Supercrono I believe, and thought I liked it.It seemed like it did away with most of the problems with screens and error readings and such.Provided it was set up right.
Now I'm kinda leaning towards the Magnetospeed.It does seem like a nobrainer that it would effect impact point.As I work up a load, I'm looking at group size as well as pressure indications.That would make the decision for this one difficult.
Now if I went with the Oehler, wouldn't I have the same problems with error readings and no reads as any with skyscreens.
