How it differs from its neighbors
Moving up a step means a Double-D coil. The ACE 400 pairs 10 kHz with an 8.5 x 11-inch DD coil, and its Iron Audio voices iron you have discriminated out. Garrett puts headphones included in its box. The detector weighs 2.9 lb.
Below it, the ACE 200 trades settings for simplicity. Its frequency is fixed at 6.5 kHz, and Garrett lists 3 search modes with 4 levels of sensitivity at 2.75 lb. Of the four ACE models in Garrett's table, only the ACE 200's coil is called submersible in shallow fresh water.
Then there is the ACE 250, at 2.7 lb. It matches the 300 on modes and 8 levels of sensitivity but drops to 6.5 kHz. Garrett's table gives it no digital target ID.

Questions about the ACE 300
Answered from Garrett's product page, read Oct. 16, 2026.
Garrett does not say. No rating appears for it on the product page or in the ACE table. The listing title claims a waterproof coil, but a seller's title is not a spec sheet.
Garrett lists 8 kHz, with a frequency shift to cut interference. The ACE 200 and ACE 250 run 6.5 kHz, the ACE 400 10 kHz.
No. For the ACE 300, Garrett's table reads None included; only the ACE 400 ships with a pair. The box does hold 4 x AA (included).
