Pre-wired boards allow for neater, more efficient, and faster lab exercises. The entry level boards include the experiment blocks, which are numbered for reference to the Lab Workbook - the DC and AC boards display
the schematics right on the board next to the real circuit. This helps students make the transition from abstract schematics to real components and real circuits with speed and accuracy.
Also, Heathkit's unique fault-insertion capabilities on many boards allow real-world troubleshooting experience without the added expense of computers-as is required by some suppliers.
