Dave, as someone who has ordered one and as I type am dribbling at the gob in anticipation, I downloaded the operating manual from myLabRadars site to bone up on it. It covers off using suppressors in the manual and of course alignment for normal weapons.
I also ordered the air gun mic straight up, wasn't super expensive, in anticipation of issues.
Also, have upgraded the crappy battery power pack I have to a decent unit. I don't intend using AAs at all.
LabRadar have a few of their own Youtube clips on their site which are also good value. Cannot remember if it was on their site but saw one of a pistol shooter blasting away. He was set up and was shooting in about 5 mins with no issues.
