Hi SteveI perhaps jumped the gun a bit. After a while it gets to you this mis-information being spread by those that have not ever used some of the unit they are criticizing. I just felt the need to criticize his criticizing post. Can I not do the same ?
If your going to complain about something bad, writing to make it sound like you have experience with a certain model, you should have at least tried one out.
All companies have problems, and all detectors have little quirks about them that will annoy some users.
I am putting this to rest. This is the last I will say about this.
