Good information Paul,
Lawrenzo, I have re-read the manual where it talks about the different modes, and I recommend everybody do so. (Try to remember how each mode works and where it's best used). Paul is right, don't use the Db mode as it's a continuous mode. You might hear too much in trash. When your ear gets better you'll get more sensitive to it. Also, Db mode won't id many targets deeper than 6" or 9", depending on the soil. So, if you do use it and want deeper targets, play it's game
To me, being in Germany where coins hit all over the place, I just look for solid signals. Then I put the detector in pinpoint mode and investigate those solid signals and dig those that don't hit so wide like aluminum targets do (I dig allot though, to see if what I think it is, is correct). Also, you will start noticing that the T2 is very sensitive, almost too sensitive. You are going to hear allot but here is something I've learned. Those short sharp signals (they also are very short in Pinpoint mode) are small targets. Don't let the depth meter fool you.
When I first picked the machine up, maybe the first week, I was just overwhelmed cause you hear everything. Hearing 3 or 4 different targets on a sweep is normal. (ie. "sounds running into eachother")(You are hearing more than any other detector can tell you). Pick out the numbers you are looking for. (I hear the T2 averages up and not down with colocated targets so take that into consideration). Start to notice the width of the signals.
A great way to understand any machine is to dig lots of targets. BUT, before you dig, note the numbers, note the depth, note the tone, note the width in pinpoint, note the clarity, note if the numbers jump around... before long your brain will just know and recognize. I think for that reason, most people get good with almost any halfway decent detector as they understand it's language. Well bro, you got one good detector there, just take time to understand it. Compare the target in modes. Like Db compared to 3 comparted to 2+ (ie. in iron). Play with all metal later on. You essentially have 2 or 3 detectors if done properly.
In closing I'll tell something I tell my German students learning English. Throw out German when learning English as it gets in the way. In this case, don't compare this machine, try to learn it's language. It's fast and tells you everything. To you that may sound like jumpiness, it's not, it's id'ing targets individually that most machines combine.
Hope that helps,
