Flir TK Scout  (2019 Update)


October 2019

It has been over 3 years since I purchased the Flir TK Scout Thermal Imager.  This article is an update on my initial review of this thermal imager, Flir TK Scout.  Since my purchase, I have used this unit countless times on many wilderness adventures.  I have also used this unit in my professional career as a law enforcement officer as well.  This unit has been an invaluable tool for me over the years, especially when I have used it at my nighttime basecamps.  I have not had any issues with the use of this unit. The durability, functions, and features of this unit have allowed me identify objects and wildlife near or around my basecamp. 

A thermal imager is my choice when it comes to spotting and identifying objects in a wilderness area.  It has its advantages over night vision optics, because it detects heat given off by objects and living things. Night vision Optics need ambient light or IR (Infared), light for them to function effectively.  A thermal imager also can be used during the daylight hours to detect and identify heat signatures given off by objects.  This unit is not cheap but affordable.  The cost is much less than other thermal imagers in the market.  The Flir TK Scout is an affordable thermal imager with the necessary features to enhance your safety in a wilderness area. The unit has its limitations on resolution and target detection distance whereas the more expensive units do not.

Applications that a Flir TK Scout can be used for:

  • Wilderness Backpacking
  • Hiking
  • Home or Business security
  • Boating
  • Fishing
  • Camping
  • Detecting moisture in drywalls or AC leaks
  • Other Applications
Weminuche Wilderness

Basecamp in the Weminuche Wilderness

My use of this unit over the last 3 years has allowed me to test this thermal imager in some very remote and rugged wilderness areas.  My most rugged use came when I was in the Blue Range Primitive located in Arizona.  I was glad I had this unit while I was exploring an area near a habitat of Mexican Gray Wolves.  I was able to make informed decisions while I was at my nighttime basecamps.  The TK Scout has a compact and durable design which allows you to use it in various temperate and wet environments.  The unit allows you to use 8 different color palettes for various applications.  The TK Scout requires no case for you to store it in.  You can throw it in your pocket for quick deployment or in your backpack without worries that it will be damaged.  Below are my pros and cons with this unit.


  • Small and compact
  • Durable (Rubberized external case)
  • Waterproof
  • Various features such as: 
  1. 8 Color Palettes
  2. Ability to record internally photos and videos.
  3. Large eye cup
  4. Built in battery and easily charged using a solar panel or battery pack.
  • Easily stored and packable
  • 5 second start up


  • Affordable but for many still expensive, ($500 to $600 Dollars).
  • Limited range for accurately identifying objects
  • To change out the battery you need to send it back to the manufacturer, (Flir) for replacement.

The  specifications indicate that this unit will reach out and identify objects up to 100 yards.  I have found that I can identify objects between 50 to 75 yards not the 100 yards indicted.  At 100 yards you will see a heat signature of an object, but you will not be able to readily identify what it is.  This unit will reach out past 100 yards which is still good letting you know that something is there.


My personal experience using this unit has been very positive.  The battery has maintained itself over the years with no notable signs of wear. I am guessing that as time goes on that I will eventually need to send it back to the factory to have the battery replaced .  As a solo wilderness backpacker my safety and security is important.  My purchase of this unit was well worth the investment. I am not a payed sponsor nor was I given this unit for free. My intent on providing you this update was to give you my personal opinion on this unit to give you information so you can make an informed decision on buying it. I believe that this thermal imager will enhance your security and safety in a wilderness area without adding bulk to your adventure.

Garmin inReach Explorer Plus

Garmin GPS inReach Explorer Plus


The Garmin inReach Explorer Plus is modern technology that all wilderness backpackers should have with them on their wilderness adventures. As a solo backpacker I always carry a GPS Satellite Communicator with me. There are various types of satellite communicators in the market. I have used different types and the Garmin inReach Explorer Plus is my first choice when I decide to head into a rugged and remote wilderness area.

The Garmin inReach Explorer Plus is the newest version of the older Delorme InReach Explorer. Garmin acquired Delorme and they merged companies. Garmin then came out with the new InReach Explorer Plus.

The Garmin inReach Explorer Plus has many new features with an upgraded ergonomic look and feel. One of the new features this unit has is the 24K topographical map. The earlier version (Delorme inReach Explorer) did not. The Garmin inReach Explorer Plus uses a text messaging system to communicate with family and friends using satellites.

A paid subscription is required to use this feature. This unit will also allow family and friends to track you on a map anywhere in the world. The Garmin inReach Explorer Plus can connect to your phone via Bluetooth so you can type with ease and view a larger screen. The Garmin inReach Explorer Plus uses the Iridium satellite system to send and receive texts.

As with all GPS communicators, there is some lag time when sending and receiving these messages depending on where the satellites are positioned in the sky. If you are indoors or in an area without a clear view of the sky sending and receiving a message may be difficult as well. The Garmin inReach Explorer Plus allows you to do some of the following:

• Send and Receive text messages 
• Get weather forecasts based on where you are located.
• View a built-in Topographical map.
• Send SOS messages in emergencies (subscription required).
• Set waypoints and routes.

The Garmin inReach Explorer Plus uses a subscription service for its data capabilities. The unit can be used with its GPS functions without paying for this service.  If you do not have the subscription then the data communication to include SOS features will not work. 

Garmin offers different subscription plans. One of the plans is called the Freedom plan. This plan allows you to use the Garmin inReach Explorer Plus on a month-to-month basis.  Utilizing this plan allows you to put the unit in a suspend mode and you do not insure any fees. For further information on the plans go the Garmin web page at https://explore.garmin.com/en-US/inreach/

My Field Test Of The Garmin Fenix 5X

I field tested the Garmin Fenix 5X in the Kalmiopsis Wilderness located in the Southwest portion of Oregon.  The Kalmiopsis Wilderness is a very remote and rugged area and it was a perfect place to test out this watch.  I started out from the Briggs Creek Trailhead and I headed west.

Before my trip, I downloaded (2) routes and several waypoints.  I used the waypoints as markers to test the accuracy of my Fenix 5X. During my 6 days and 5 nights in the Kalmiopsis my Garmin Fenix 5X did not lose a GPS signal.  It kept me on my routes and it found all of my waypoints.

Navigating with my Garmin Fenix 5X

I was very happy with the navigational features of this watch as I bushwhacked off the trail.   While on my adventure, I charged the watch 4 times, using my solar panel, during my 5 night 6 day journey in this Wilderness.  Overall, I enjoyed using this watch and I will be using it on other future wilderness adventures.

Flir Scout TK (Thermal Imager)

Flir Scout TK Thermal Imager


The Flir Scout TK is a pocket-sized thermal imager that you should consider having on your wilderness adventure. The FLIR Scout TK allows you to see objects that emit a heat signature such as a person’s body heat.  Thermal imagers have historically been very expensive to buy. The introduction of the FLIR Scout TK has changed this

The FLIR Scout TK is lightweight unit that can reasonably detect objects up to 100 yards away. The unit runs about $600 dollars before taxes.

The FLIR Scout Specifications

  • Weight: < 7 oz.
  • Detector Type 160 X 120 Microbolometer
  • Refresh Rate: 9Hz
  • Field of View: 20 Degrees x 16 Degrees
  • Display: 640 X 480 LCD
  • Battery: Rechargeable Lithium (5 Hours Run Time)
  • Images: Able to take up to 1000 images
  • Able to take up to 4 hours of video
  • Color Palettes: 8 color selectable

I did a field test on this unit while on a wilderness expedition in the Hells Canyon Wilderness located in Idaho. The unit is not only portable and lightweight (less than 7 oz.), but also very durable. Throughout my 4-night 5-day adventure I had the unit in my pocket or in my backpack without a case. I never had to charge the unit during my trip and I used it at my basecamp in the evening.

Having this unit with you in a wilderness area allows you to have a safe and more relaxed stay at your basecamp at night.  All thermal imagers can be used in complete darkness during the day since it detects heat and not light. 

The FLIR Scout is very simple to use and it has 8 color palettes to choose from.  This unit can also be used around your house for security or for other daily activities when you are not in a Wilderness environment .

Below is my FLIR Scout TK video that I made while on my adventure in the Hells Canyon Wilderness (Idaho). The introduction of this affordable thermal imager it is something you may consider having on your next wilderness adventure.
