Right on Gila, I hear ya talkin'. Don't worry, you'll get used to the Quatro, and all it's little trips. I've had my Quatro for over a couple of years now, and I thought I knew it, but I've recently realized that I need to take a very dedicated 2nd look at what it's really saying to me. I know this "bad boy" works, not only from my own experience, but from what I've been reading all along about it on this forum. The thing I'm trying to do now is "really listen" and "look" at the visual and audio signals. I thought there might be something wrong with mine because I was getting tons and tons , alomost non-stop signals, just yesterday at the bay down here where I live, but when I moved over to another area, it was picking out each individual signal. This thing just seems to read everything in it's sight, and try's to tell us what it is. Golden is right. We just need to "listen" to what it's trying to tell us. I know that sounds like something you and I already know, but I just think it's SO TRUE, for the Quatro. The other thing I wanted to say here, in regards to the "outer limits" of depth, is something I read on another forum from another Quatro owner. He said: "If you don't even HEAR, a signal, but when you put it into pinpoint mode, if that little visual thing they have goes up "even a hair's breath", (AS HE PUT IT), YOU'VE GOT SOMETHIG!!!!. Wow!!!!, That's hard work, but, you know, if he's right, this darn thing won't just stop at the audio level, but sends us infor of a target from the visual level as well that may even superseed the audio. What a bitchen detector. I love this thing, and I hope you fall in love with it too. (Look out Explorer II owners, we're comin' to get ya):| Well I'm probably going over board here, but maybe not. The main thing the Explorer has over us as far as I can see is the two numeric readouts, but as far as depth, LOOK OUT.:| Take care and I'll talk to you, at least by the first of the year. Marc.
