SPROG II provides a one-stop source for setting up and running any DCC locomotives; ideal for off-layout programming and test set-ups.
SPROG II has sufficient power to program sound decoders, even in large scales, so no power booster is necessary.
SPROG II works with all those "difficult" decoders that don't seem to read back on other systems.
SPROG II also includes the ability to test your locos, or run your layout, with on-screen computer control, and full DCC operation.
