Setting the sensitivity on the Whites TRX
Below are some helpful points that may not be in the user manual of the TRX. These came from the Whites Forum.
There is a sensitivity control on the TRX. Here are the general settings for sensitivity - the default is 3. Intended to be about 3.5". Sensitivity 1 = Bullseye II depth (about 1"), sensitivity 2 = Garrett ProPointer depth (about 2"), sensitivity 4 = around 4-4.5" - and it is likely to false on this setting, but some areas may be able to use it. It's not in the manual obviously. But here is how to get there:
First option:
1) Go into config (press and hold the button through the power down beep until you get to the taDAH beep for config).
2) Release and repress the button. Hold the button for 5 seconds. The indicators will indicate your sensitivity setting. The first set of beeps will indicate your current sensitivity setting (you should hear 3 beeps for the default sensitivity being 3). The next set of beeps will be the next one (4 beeps for sens 4), the next will be the next one (wrap around to 1 beep for sens 1). Release the button at the sensitivity level you want to be at. Might help you out in the tot lots.

Control Priority:
If you find yourself wanting to change sensitivity more than once and you want it on the "main menu" without that 5 second delay, there is a test mode which all it does is move the "menus" around.
1) Go to config mode
2) Release the button and then press and release 3 times.
3) Wait for config exit - you should get a dadadaDAH jingle.
Now your menus are switched around unless you do a factory reset (more later)
4) Go to config mode
5) Keep holding the button down - the sensitivity is the first menu rather than the indicators. release the button when you get to the sensitivity you want.
In this mode, the first menu is sensitivity. 2nd menu (release button after config and press and hold) is the indicator adjust. 3rd menu (release button after config, press and release once and press and hold) is audio adjust. This adjusts the frequency of your audio - so if you hear a lower frequency better than the one that the pinpointer is set to, you can find one that might be better. It has a very limited range, so it's possible that there won't be any difference.
Factory Reset:
If you want to put it back to the menu system that it came with, you can do a factory reset. This will reset everything - except the audio frequency - back to how it came from the factory. Go to config, release and press the button 6 times.
