What prevents modification to the Prizm? The system board or the casing?

Alot of these newer-breed machines are microprocessor controlled, with everything programmed into the software rather than having physical characteristics that can readily be modified. I would bet the Prizms are the same way. Bill would know for sure.

With the excellent Classic series you have a very quick response and fast recovery rate when you sweep across a target in the Disc. mode. With the Prizm series, you don't. They have a delayed response when you sweep over a target. They work differently. I read errantly reported comments early on that the Prizm's were ust Classic circuitry, and that isn't so!
One nice thing about the Classic's is that they have an easily accessed GB trimmer, and that GB adjusted BOTH the All Metal and Discriminate GB function.
The Prizm series has a less accessable and much tinier GB trimmer. Quite fragile by comparison. Also, I have found them to NOT function well to get a good balance between both modes, leaving me to wonder if they have two GB trimmers, or if one more is a factory preset or microchipped setting.
I have used Prizm's that had a too negatove GB setting in All Metal/Pinpoint, and too negative in the motion Discriminate mode. Some that were too negative and too positive. One that was too positive and too negative. And in the three cases where the trimmer was adjusted it didn't do anything to correct the fasing issue with one of the modes.
The gal who designed the circuitry maybe didn't understand that some of us like to have a detector with more versatility to it, both in GB adjustment and discriminating range and performance.
