My 6000/Di PRO SL has been described on this forum as a detector that has a medium or fast sweep speed. What effect does the sweep speed have on an operators efforts to decipher his detector's signals? My guess is that each type detector would have its pros and cons but I don't know what they might be. Also which analog detectors fit in each category?

Medium sweep/Slow sweep

You can prove answers to your own question with a simple bench test. Set up the detector and sweep a dime about 6 inches under the coil at what you would consider a "normal" sweep speed. Now, continue sweeping the dime under the coil, speeding up your sweep with each pass. With the 6000 series, as you speed up, you will find the target audio stays strong and will likely get stronger. Move the dime farther away from the coil and notice that faster speeds will allow you to increase the depth of detection.
Now that your arm is tired, start again at your "normal" sweep speed. This time, slow down the sweep speed with each pass under the coil. You will find that you must move the dime closer to the coil to maintain a target audio tone. Eventually, when you get real slow movement, you will not get a target signal. In fact, you will be able to stop the dime directly under the coil and not get a response.
The analog detector that comes to mind as being the "opposite" of the 6000, as far as sweep speed, is the Fisher CZ-5. You will find that a slower sweep speed is required for it to perform as designed. When you sweep it too fast, it will miss the targets, similar to the 6000 when it is swept too slow.
Lots of factors play into this. Number of filters, tracking and coil design, to name a few. There are some great users on here that might want to take a crack at further addressing your questions. HH Randy

If you have the early blue-box 6000/Di Pro you're more limited, but if you have a newer 6000 Di Pro SL with the Signal Balance control, increasing that control to a setting just below the point of instability will greatly enhance the depth of detection AND permit a much slower sweep speed that a lower setting.

Great idea! I will do the bench test for sweep speed. I am sure it will improve my understanding of how my detector might function at its best.
Does my 6000 SL have a sweep speed that is very close or possibly functionally identical to that of the XLPRO?
I have a 6 1/2 inch coil in the mail that should be here soon. I am anxious to try it out and find the functional differences between it and the stock 9 1/2. My faith in this old machine is steadily growing as is the treasure pile that I have dug with it.
I just bought the book "Taking a Closer Look At Metal Detector Discrimination". I am only half way through it and already realise that it is truly a fantastic source of information!
