I use a Fisher F2 but my aunt said she wants to try metal detecting, so she went out and bought herself a Spectrum XLT. When we go out next month it will be her first time so I need to be ready to show her how to use her machine. I've never used it before, so I came here to find out if it's something with a big learning curve or something that I can pick up on quickly and get her going right away.
Thanks!
Your aunt has good taste.
One of the best things about White's detectors is their "turn on and go" philosophy. Apparently, they figured out early on that folks just don't like to spend hours poring over an operator's manual before they ever turn on the detector, so they incorporated markings on knobs that (when used) will produce good results, and preloaded settings that do the same for the digital models.
Considering that her detector is used, you may want to sit down with the owner's manual beforehand and compare the factory settings in the book to the settings on her detector. If they have been modified, you can easily change them back to factory. This will give her the proper context for learning how her machine responds to targets in various environments. If you don't have a manual, White's has them in PDF for free:

The settings are all menu driven (of course) and straightforward. I would personally recommend the Jewelry and Coin program to start, since it has less discrimination than just coins.
White's detectors have a reputation of "banging in" on good targets. There are a couple things for the operator to keep in mind.
1. The key to identifying good targets is repeatability. If the VDI bounces around, or the audio is broken, it's probably junk.
2. The signagraph is often ignored, but a very important tool in good versus bad target ID. As the bars build up, they tell a story. A single, tall bar in the positive range is going to be a good target. "Smeared", short bars in the negative range are junk.
Pinpointing is easy and accurate. Once a target is found, simply stop the coil over to the side a bit, pull and hold the trigger on the pod (this puts the detector in the all metal mode), and slowly move the coil over the target. Look for the lowest depth number and the loudest (or highest pitched) audio. The target will be under the center of the coil.
Changes you'll want to make:
Target volume may be too loud for most, since it is set for use without headphones
Threshold is too loud for most - turn it down to 17 or so if using headphones
Turn ratchet pinpointing OFF
Turn tone ID to ON
VCO to ON
Modulation to OFF
All other settings left at default
Ratchet pinpointing can cause a new user to lose the target and cause confusion
VCO causes the target signal audio to increase as target strength increases
Modulation OFF causes all targets to respond the same regardless of depth. A new hunter really doesn't need to be worrying about "whisper signals" at this point.
A good set of headphones will increase battery life and just generally make hunting easier all around.
My final piece of advice is: don't get all cranky when she spanks you out there!
Good luck!
