The AT Pro is an excellent machine and is waterproof to 10 feet. Is is great to use for relic hunting, coin shooting and in freshwater. The Apex uses different technology which is newer than what is being used in the AT Pro. The Apex uses 4 frequencies at one time which makes the machine a bit more stable in salt water and mineralized soil.
