BATTERY REPLACEMENT

1.  Turn either instrument (Transmitter and Receiver) over on its face and remove access plate with coin or large blade screwdriver.

2.  Lift the battery pack out carefully. Turn the battery pack slightly, unsnap the battery connector and slip off the sleeve. Change all eight batteries. Slip the sleeve back on, then reattach the connector to the pack. Slip the battery pack back into its compartment and do a battery test. Refasten the access plate. Both the transmitter and receiver will work from 30 to 40 hours on a set of 8 standard quality, carbon-zinc batteries. Alkaline batteries will give substantially longer life and in cold weather will perform much

better than standard carbon zinc batteries.

NOTE: As supplied from the factory, the battery pack is surrounded by a plastic sleeve to retain the batteries during possible rough handling and shipping. As a precaution, always reinstall the sleeve after battery replacement.

GEMINI-3 specifications

The Fisher GEMINI-3 is a sophisticated metal detector designed for both hobbyists and professionals seeking high-performance in treasure hunting. Launched by Fisher Research Labs, this model offers a myriad of features that make it one of the most popular detectors on the market.

One of the standout characteristics of the GEMINI-3 is its dual search capabilities. The detector is equipped with both a 10-inch coil and a 5-inch coil, allowing users to operate in various terrains and conditions. The larger coil is perfect for searching wide areas, while the smaller coil helps in pinpointing targets in more cluttered sites.

The GEMINI-3 utilizes advanced VLF (Very Low Frequency) technology, which provides enhanced sensitivity to both ferrous and non-ferrous metals, helping users to distinguish between valuable items and common trash. This technology significantly reduces the chances of missing hidden treasures beneath the surface.

Another impressive feature is the detector's digital target identification system, which provides users with a numerical readout corresponding to the type of metal detected. This identification system enhances the hunting experience, allowing users to make informed decisions about whether to dig or move on to the next target. Additionally, the GEMINI-3 boasts multiple discrimination modes, enabling operators to filter out unwanted items like iron and foil while honing in on more valuable finds.

The GEMINI-3 is built for durability and usability. The control panel is user-friendly and designed to facilitate quick adjustments in the field. The lightweight construction of the detector ensures comfort during prolonged use, making it an ideal choice for long treasure-hunting sessions.

Moreover, the detector is powered by a rechargeable battery, providing extended use without the inconvenience of constantly changing batteries. The impressive battery life allows treasure hunters to focus more on their quest and less on equipment management.

In conclusion, the Fisher GEMINI-3 combines advanced features with user-friendly design, making it a top choice for metal detection enthusiasts. Its versatility, technology, and practical characteristics empower treasure seekers to explore various environments efficiently, unearthing hidden treasures with ease.
