Garrett ACE 300 Metal Detector
The Garrett ACE 300 is a coin, relic and jewelry detector that sits in the middle of Garrett's ACE line. It runs at 8 kHz for solid sensitivity to low and medium conductivity targets, and the operating frequency is adjustable so you can shift it to clear electrical interference. A digital target ID reads each target on a 0 to 99 scale, so you get a numeric read on what is under the coil before you dig.
The ACE 300 ships with the 7 inch by 10 inch PROformance searchcoil, which is submersible for hunting wet ground and creek edges. Five search modes plus Pinpoint, eight sensitivity levels and notch discrimination let you set the detector for the site and the target. A large LCD shows the target ID, a coin depth indicator and a battery condition indicator.
The detector weighs 2.8 lbs (1.27 kg), adjusts from 42 inches to 51 inches and runs on four AA batteries that are included. Camlocks on the stem keep it steady in use, and the ACE 300 is made in the USA.
GeoWork Supply ships the ACE 300 packed with its searchcoil cover and the owner's manual linked below. It suits new and weekend detectorists who want digital target ID and adjustable frequency in a light, easy to run machine.

Features
8 kHz Adjustable Operating Frequency
The ACE 300 runs at 8 kHz, a step up from the ACE 250, for better sensitivity to low and medium conductivity targets such as gold and lead. The frequency is adjustable so you can shift it to clear interference and hunt close to another detector.

Digital Target ID, 0 to 99 Scale
A digital target ID reads each find on a 0 to 99 numeric scale so you can judge a target before you dig. The expanded target ID legend above the screen also flags US coin denominations.

7 by 10 in PROformance Submersible Coil
The included 7 inch by 10 inch PROformance searchcoil gives good coverage and depth for a detector in this class. It is submersible, so you can hunt wet grass, puddles and creek edges without worrying about the coil.

Five Search Modes Plus Pinpoint
Five search modes plus electronic Pinpoint and eight sensitivity levels let you tune the ACE 300 for coins, jewelry, relics or trashy ground. The coin depth indicator shows how deep a target sits before you start to dig.

Increased Iron Resolution and Notch Discrimination
The ACE 300 has twice the iron resolution of the ACE 250, which helps it pull good targets out of iron-laden sites. Notch discrimination lets you accept or reject specific target segments based on what you are hunting.

Built for Coin, Relic and Jewelry Hunting
The submersible coil, digital target ID and adjustable frequency make the ACE 300 at home in parks, yards, fields and old home sites. Pushbutton controls keep it simple for a new detectorist to learn.
