How to Use GPS with Metal Detecting for Precise Location Tracking?

Can you imagine that a gadget would be the digital memory of your adventures in metal detecting?

Metal detecting is not as easy a task as it may seem. Just sweeping a device on the ground in your hand is not the game, especially when you are a beginner in metal detecting. It is a mixture of patience, technology, and strategy.

If you want your Metal detecting experience to be at the next level, then you must have to include GPS in your routine to improve efficiency and accuracy.

By using this technology, you will be able to track the precise location, map the search area. Also, you can mark the locations of your findings.

First of all, you must be sure that you are using a reliable GPS device. It always depends on the type of location you are selecting, how frequently you are going there, and the accuracy you want.

Key Benefits of using GPS in Metal detecting

Record important discoveries with exact location and depth.
Sync data among devices or detect partners
Track searched zones to prevent redundant scanning
Combine your routes with old historical maps.
Map property borders to ensure legal compliance.

The Result: a better-structured, data-driven metal detection process that can be repeated, examined, and improved over time.

How to use a GPS in Metal detecting?

Turning on GPS isn’t enough. Here’s a field-tested method for making your Metal detecting successful.

Pre-Plan about the desired Area:

Use GPS apps or software to see the topography maps or satellite imagery before you go. This way, you will be able to detect the desired location, excluding the building sites, abandoned areas, and any new changes.

To find possible relic zones, you should import the old maps and counter-check with the latest GPs data.

Mark your starting point:

Log your beginning place as a waypoint once you’re on location. This will help in case you lose the position; it gives you a reference point to go.

Grid Searching:

Use your GPS map’s waypoints or drawn lines to make a grid. For instance:

Mark four corners of a space that is 100 by 100 feet.
Work systematically inside the grid.
When you get finished, move to the next one.

Track the movement:

If you want to review the track you have already visited, or want to share it with others. Then there comes a feature called the breadcrumb or track log feature that displays a route that you have walked on.

Log finds with way points:

There are some GPs programs with the facility of capturing pictures, audio and written notes.

Every time you find some valuable thing, mark this with a waypoint and give it a name. Your map will eventually become a hotspot database.

Analyze and export:

After you have done the Metal detecting, try to export the data to the desktop application or Google Earth. This enables you to identify patterns, compare hunt zones, and improve your tactics.

GPs' essential equipment required for Metal detecting

There are many available in the market, like a standalone device, and some come with smartphone apps that can coordinate your findings, site conditions, and depth. You can always access the map offline, too. Also, by digital logging, it can refine the strategies and analyze your search patterns.

1. Handheld GPS Devices:

They are made for outdoor exploration as they are rugged, very reliable, waterproof and work without cellular services.
Examples are Garmin eTrex 32x and GPSMAP 66.
Features include offline functionality, waypoint marking, topo maps, and track logging.
They are perfect for remote farms, wilderness areas, and historic sites.

2. Smartphone GPS with Apps:

They are more updated than even if you have no internet connection, their built-in GPS can function when the maps are preloaded.
You may utilize apps like Google Earth, Maprika, OnX Hunt, Gaia GPS, and even Google Maps.
They are multifunctional, user-friendly, and reasonably priced.
But it has a short battery life that may not work for long hours.
And yes, they are excellent for beginners or in urban areas, for Metal detecting.

3. GPS Watches:

If you want to be hands-free from extra equipment, then this would be the best choice.
They are portable and lightweight but of course, they can’t beat the handheld devices.
Some high-tech watches, such as the Garmin Fenix, Suunto 9, and Coros Vertix, have waypoint and GPS tracking capabilities.
It is often used for casual hunting.

Things to consider while using GPS for Metal detecting

Preload the maps before you go for Metal detecting with GPS, as some areas may not have cellular coverage.
Keep with you the power bank, solar chargers, or spare batteries because devices or phones drain quickly, mainly when the GPS is being used.
In some cases, there are tall buildings or in forests, the tall trees that cause the signal loss. For this high-end GPS is better than a phone.

Best Practices for logging and recording

Some Apps like Lucky Find and OnX Hunt allow:

GPS monitoring.
Find the classification type.
Adding information and taking a picture.
Property boundary overlays

Combine this data to identify high-yield areas and find geographical trends.

Recognizing GPS Formats and Coordinates

Understand how you will read the GPS.

Common Formats:

Most apps use decimal degrees (DD).
Traditional format for degrees, minutes, and seconds (DMS)
Decimal minutes in degrees (DMM): a standard for aviation and marine
Determining your latitude first will help you a lot (for example, 43.5890, -116.2190).

Tip: If you want to avoid mistakes, then stick to the same format throughout your journey. If it is necessary to change, then learn first how to manage them.

Keeping Your Logs in Order

Utilize cloud-based diaries or Google Sheets for your records:

Trace the coordinates
Permissions from landowners
Weather conditions
Historical allusions and map overlay.

If you have a systematic approach, then your logging system will become more than a hobby.
