Question: What are the differences between the Garrett CSI 250 and Garrett ACE 250?
Answer: The CSI 250 has a different face plate on it and is set up for targets that law enforcement would be looking for. The screen shows where the bullets, shell casings, knives and guns would ring up. The Ace 250 screen is set up for hobby detecting so it shows coins, rings, pop tops, gold rings etc. The machines have the same functionality.
