GRT0008-Ace 250 Metal Detector Feature Loaded and Powerful ! Includes Search Coil, 4-AA Batteries, Operators Manual, Instructional DVD Welcome to the feature loaded GRT0008 metal detector. With 40 years of engineering prowess behind it and a head turning sporty, outdoor design, this machine was made to perform for the 21st Century treasure hunter. But don't be fooled, this detector doesn't win first in its class on looks alone! Its as new on the inside as it is on the outside. Loaded with full range notch discrimination, pinpoint feature, graphic target ID and Touch-n-Go technology, the GRT0008 is the finest metal detector in its class. It also comes with a graphic target ID cursor with 12 element GTA notch discrimination for greater accuracy, Continuous Coin Depth Indication, Tone ID, 8 Sensitivity Settings, 5 pre-set hunting modes and of course the most advanced LCD graphic screen for quick and easy visual target ID. Whew! Need we go on? GRT0008 Metal Detector Features: Graphic Target ID Cursor (12 Segments) Discrimination: Accept / Reject Notch Electronic Pinpoint Continuous Coin Depth Indicator Sensitivity, Depth Adjustment (8 Settings) Tone...

• Enhanced Iron Resolution™: allows more control of iron discrimination levels; helps separate good targets from adjacent junk iron. • Powerful new Double-D searchcoil: provides greater detection depth and performance in mineralized grounds and excellent scanning coverage. • Higher Frequency: offers improved ability to detect low- and midconductivity items (i.e. gold nuggets, jewelry, lead relics) • Volume Control Headphones: included with purchase • Electronic Pinpointing: to precisely locate target and speed recovery • Accept/Reject Discrimination: to modify discrimination patterns • Five Search Modes: select pre-set discrimination pattern or create your own • Continuous Coin Depth Indicator: to determine target depth • Battery Condition Indicator: shows battery life continually • Interchangeable ACE series searchcoils: are available • Other features: One-Touch operation; 3-piece travel/storage, disassembles to 24"; adjustable arm cuff; quarter-inch (1/4") size headphone jack.
