I just got a Fisher f19, and so far I love it. Haven't used my F19 too much, but so far I'm amazed at how light it is, how fast it is, and how stable the tone ID numbers are. One thing that I noticed right away is that it is top heavy, meaning you set it down and it falls over. So I thought I'd share my solution. I've seen these pvc "kickstands" posted elsewhere, but thought I'd post mine as well. Altogether parts were about $3. Makes the detector very stable. Hope this is helpful.
