The Garmin Montana 680t is a standout in its category thanks to its preloaded maps, built-in compass and altimeter, integrated 8-megapixel digital camera that enables you to capture those beautiful moments, and a 4-inch color touchscreen display that works even under the sun or if you have gloves on.

Before you purchase a handheld device, there are various aspects to consider.

First, consider durability and reliability. The Garmin Montana 680t is built to be rugged and last through years of outdoor adventures.

If you want a device that will hold up to rain, you should purchase a waterproof GPS device. The 680t is an excellent choice for this, as it features IPX7 waterproofing.

What does this mean?

This means the device can withstand being submerged 1 meter underwater for 30 minutes.

Battery life is an important characteristic of any portable device.

The 680t lasts up to 16 hours with the built-in lithium-ion battery, or you can also insert AA batteries for up to 22 hours of battery life.

While this is respectable

…there are other GPS units with much longer battery life, such as the Garmin Montana 750i, which can reach up to 330 hours in expedition mode.

Another important aspect is the device’s screen size and type.

The 680t has a 4-inch transflective (meaning it’s easy to read in the sun) touchscreen display with bright colors and high resolution. You can also use it with touchscreen gloves.

Also, consider the navigational systems and accuracy.

The 680t has built-in GPS and GLONASS system capabilities. These refer to the global navigation satellite systems that the device receives signals from. The more systems a device can interface with, the more accurate the GPS will be. Some GPS devices also have integrated Galileo.

Another feature to consider is whether or not you need a camera.

The 680t includes an integrated 8-megapixel autofocus digital camera so that you can capture those critical moments on your adventures.

Features & Benefits

Weight and Size

Weight and Size

The 680t weighs 10.2 ounces (289 grams) and has an overall 2.9 x 5.7 x 1.4 inches. With three AA batteries installed, the device weighs 11.7 ounces.

While this is not the smallest GPS device on the market

…it is lighter than many of Garmin’s other GPS offerings while also slightly shorter and narrower. This makes it relatively lightweight and compact.

However, the 680t may be a little too bulky to fit inside some pockets.

On the other hand, this is not the main purpose of the device as it’s meant to be displayed on a mount while in use for easy viewability and navigation.

Garmin Handheld GPS Device Navigational Technologies



The 680t is equipped with GPS+GLONASS satellite system technology. GPS is a global navigation satellite system owned by the United States, while GLONASS is Russia’s. Since the 680t can interface with two different satellite systems, it has the potential to more accurately pinpoint your location than a device that only has one or the other.

The 680t also comes with 100,000 U.S. topographical maps preloaded on the device, which is rather convenient and makes navigation a breeze. This is especially useful for geocaching adventures.

In addition to that…

…the 680t is also designed to find a satellite signal even in areas where receiving a signal may be more challenging, such as the wilderness or around taller buildings.

This ensures the reliability of the device when you need to find your way.



Furthermore, the 680t features an electronic compass with 3-axis tilt capabilities, which enables it to continue navigating correctly even if the device is tilted at an angle when in use.

Barometric Altimeter

There is also an integrated barometric altimeter, which monitors and tracks your altitude by measuring pressure changes as you move. This is also sensitive to weather changes that affect barometric pressure, so you can use it to track the forecast.

BaseCamp and City Navigator Software

BaseCamp and City Navigator Software

The Garmin BaseCamp software is a useful way to follow your customized maps and routes, allowing you to plan your trips with ease.

The track manager organizes up to 200 routes and waypoints for easy navigating. You can also upload City Navigator map data so that the device will give you turn-by-turn directions as you drive on the road.

Waterproofing is an important feature if you plan to use your device in rainy or snowy conditions.

With a waterproof rating of IPX7, the 680t can withstand immersion in up to 1 meter of water for up to 30 minutes. This is more than enough for rainstorms on the go.

Battery Life

The built-in lithium-ion battery lasts up to 16 hours.

While this is reasonable

…you can find other devices that last longer if battery life is the main concern. Thankfully, the 680t can also be powered with three AA batteries (not included), giving an additional 22 hours of battery life. You can also charge the device while you use it.

This video shows how to insert the battery and charge your device before set-up.

While this video uses the Garmin GPS Montana 610/680, the same procedure applies to the 680t.

The 680t has a 4-inch display with a resolution of 272 x 480 pixels.

The screen is transflective, meaning it reflects ambient light in your environment to create a bright enough display to see without a backlight (which would consume more battery life). It is also easy to read in the sunlight without washing out.

Another great feature of the screen is that you can use it with touchscreen gloves, which is important in chillier weather.



With the built-in 8-megapixel autofocus digital camera, you can quickly capture your memories along the trails.

Even better

…when you take a photo, the device geotags it so that you can easily navigate back to those exact coordinates if you wish to revisit that same spot in the future.

There is an integrated microSD slot (card not included) for more storage of your favorite photos.
