When Primitive Skills Meet the Digital Era-Using Apps and Modern Technology in the Wilderness

by
One of the principles I teach my students at Arcturus Primitive Skills Institute is this: I am, and always will be, a student.
 
Take edible and medicinal plants, for example. While I’ve accumulated a substantial amount of knowledge, the learning never ends. There is no way I’ll ever master every single plant’s use on this planet—and that’s the beauty of it. I carry that same mindset into every aspect of survival and bushcraft. Whether it’s new techniques or better tools, I’m always refining, always evolving. What I haven’t learned at formal survival schools, I hunt down on my own.
 
One of the most effective ways I continue to grow is by leveraging modern apps and digital tools—many of which are available on both iOS and Android. These resources are invaluable to survivalists, bushcrafters, and outdoor enthusiasts alike. Below are some of the most highly rated and useful tools I use and recommend:
 
PictureThis
A powerful plant identification app that can recognize over 400,000 plant species with more than 98% accuracy. Simply snap a photo of a plant and the app will instantly return its name, species, toxicity warnings, and detailed information. I often use this as a springboard before researching a plant’s edibility and medicinal properties online.
 
Knots 3D
If you want to master knot-tying, this is your go-to app. It teaches over 200 knots with 3D, 360° interactive views—immensely helpful when trying to understand complex configurations. For a real challenge, try wrapping your brain (and fingers) around the Evenk Hitch.
 
MyRadar
Skip the clutter of traditional weather apps. MyRadar offers clean, fast, and accurate radar maps with real-time weather alerts—essential before heading into a course with students. It outpaces traditional sources like The Weather Channel or AccuWeather by avoiding distracting pop-ups and advertisements.
 
Spyglass
A navigation powerhouse that turns your phone into a survival toolkit. With features including offline maps, augmented reality navigation, a digital compass, GPS, waypoint tracking, and even star catalogs, Spyglass is indispensable. When you’ve forgotten your compass or paper map but have your phone (and a reliable power source), this app can guide you through.
 
Gaia GPS
Perfect for those who prefer a streamlined GPS app. Gaia offers detailed maps and route planning and is known for being more reliable on the trail than its popular competitor, AllTrails. AllTrails excels in route planning, but Gaia shines in execution. I personally prefer Gaia but encourage others to try both and decide which suits them best. Advanced features require a subscription.
 
First Aid by the American Red Cross
This app could literally save a life. It provides offline access to step-by-step emergency instructions for burns, cuts, CPR, choking, and more. It includes a hospital locator, 911 integration, educational videos, interactive quizzes, and receives regular updates. Best of all—no ads.
 
Zello Walkie Talkie
Transforms your phone into a real-time push-to-talk radio. With both public and private channels, voice playback, and compatibility across platforms, Zello is bandwidth-efficient and reliable in emergencies. It also supports Bluetooth headsets, offers text and image sharing, and encrypts your messages.
 
Signal
For secure communication, Signal is unmatched. It uses end-to-end encryption that even the developers can’t access. It’s free, ad-free, and open source. Messages auto-delete based on user settings and are never stored on external servers. It even supports groups of up to 1,000 participants.
 
SAS Survival Guide
Based on the bestselling book by former SAS soldier John “Lofty” Wiseman, this app offers offline access to practical survival knowledge. It covers essential topics like fire starting, shelter building, Morse code, and sun compass use—ideal for remote adventures.
 
Pro Tips
• Combine a first aid app with a survival manual app to create a well-rounded emergency preparedness toolkit on your device.
• Organize all your survival apps onto a dedicated home screen. In a high-stress situation, you don’t want to waste time scrolling through icons.
If you’re serious about your self-reliance journey, equipping your phone with these tools can be just as crucial as what you carry in your pack. Let the learning—and the adventure—continue. 

Sleep Like Royalty on a Peasant’s Budget-This CPAP Battery Is a Game-Changer

by

Back in my younger years, I had no idea I had sleep apnea. I just knew I was always exhausted, no matter how much I slept—especially when I worked third shift at a state prison. It wasn’t until my wife pointed out how badly I snored and suggested I get a sleep study done that I began to connect the dots. Turns out, she was absolutely right. The results came back: severe sleep apnea. That’s when I picked up a ResMed AirSense 10 CPAP machine, and my sleep—finally—started to improve. Fast-forward to summer 2025. Over the past few years, whenever I did a survival weekend trip, I’d tough it out and sleep without my CPAP. It wasn’t ideal, but I managed. However, just a week before my upcoming Basic Survival 101 Course scheduled for June 20–22, I decided to do a reality check. I was camping at White River RV Park and, without my CPAP, I found myself waking up every 20 minutes. That’s when it hit me: I can’t do these weekends without my CPAP anymore. The problem? My camp has no electricity. Last summer, I watched one of my students and his two teens effortlessly charge their phones and devices all weekend using an Anker Solix portable power station—pretty sure it was the C1000X model. I was impressed, but $500 for a power solution felt steep, especially when I just needed it for my CPAP. So, I shifted my search toward standalone CPAP batteries. I explored a few: the Easylonger CPAP Battery ES400 Air at $169 (tempting, but reviews made me pause), the Night Owl (decent, but $300 felt like too much), and the Bluetti X30 (also $200, but the reviews didn’t inspire confidence). I also looked at the Portable Outlet PO-160UPSv2 and the Pilot-24 Lite from Choice One Medical, but again, the price-to-performance ratio didn’t sit right with me. If I’m dropping serious cash, I want five-star peace of mind. And then I found it—the Renogy 72000mAh 266Wh 12V Power Bank and CPAP battery. Nearly five stars, with reviews from people who used the same CPAP machine I do and claimed it powered their sleep for multiple nights without a recharge. Sold. I ordered it on Amazon for $159 with overnight shipping. When it arrived, the battery was about 75% charged. I topped it off in preparation for the weekend. The battery came with two USB-C PD ports and a DC 12V/5A cigarette lighter port—perfect for my AirSense 10. I did have to purchase a separate ResMed DC adapter for around $29, but once that arrived, I was ready. Friday, June 20, was long—setting up camp, greeting and assisting students, then jumping into training. By the time I finally crawled into bed, I was wiped. I plugged my CPAP into the Renogy and hoped for the best. It delivered. The battery powered my CPAP the entire weekend without needing a recharge. By Sunday, I still had over 50% battery life. I even used the USB ports to charge my phone. The only minor issue I ran into was that if I bumped the cords too hard while sleeping, the CPAP would shut off—but aside from that, I was seriously impressed. Let me be clear: I’m not sponsored by Renogy, and I don’t get anything out of recommending them. This CPAP battery is still new to me, and I’ll see how it holds up six months from now—but based on this experience, I can say with confidence that the Renogy battery is the best bang for the buck I’ve come across.

Wheeping Forsythia: Medicine of the Yellow Flower

by

Wheeping Forsythia

Weeping Forsythia (Forsythia suspensa) is a hallmark of spring, and one of the first bloomers to catch my eye each season. I typically spot this plant alongside Snowdrops early in the year. It has been valued in traditional medicine since ancient times for its numerous health benefits. The yellow blossoms can be eaten raw, though they are bitter. However, the flowers make a pleasantly flavored tea. Below are some of the plant’s medicinal uses:

• Anti-inflammatory properties: Weeping Forsythia contains compounds such as phillyrin and forsythoside, which help reduce inflammation throughout the body.

• Respiratory health: It can reduce inflammation in the air passages of the lungs (bronchiolitis).

• Antibacterial properties: The plant inhibits the growth of bacteria such as Staphylococcus aureus.

• Antiviral benefits: Prepare a tea using the flowers and consume it when dealing with colds, the flu, or other viral infections. Gargling the warm tea can also soothe a sore throat. Additionally, it boosts the immune system, aids in tonsillitis relief, and reduces fever.

• Allergy relief: In spring, I use this plant along with Purple Dead Nettle to alleviate allergies.

• Heart health: The plant contains oleanolic acid, which supports heart muscle function and helps regulate blood pressure.

• Pain relief: Weeping Forsythia’s analgesic properties are effective for relieving pain and headaches.

• Topical applications: Prepare a fomentation or wash with the plant for antiseptic use. The tea can be used to clean wounds, cuts, burns, rashes, and other skin problems.

• Support for internal organs: The plant is beneficial for liver health and can help regulate blood sugar levels.

Methods to Prepare Weeping Forsythia for Medicinal Uses:

  1. Tea: Use a tablespoon of fresh or dried yellow flowers and steep them in hot water for 10–15 minutes. This tea helps with fever, sore throat, and inflammation.
  2. Tincture: Fill a mason jar with dried fruits and leaves, then cover them with vodka or brandy. Seal the jar and let it sit for 4–6 weeks, flipping it upside down once a week. Afterward, strain and store the liquid. This tincture offers potent medicinal benefits, boosting your immune system and aiding in fighting infections.
  3. Infused oil: Place dried flowers in a jar and cover them with almond, olive, or coconut oil. Let the jar sit for 4–6 weeks, then strain and store the oil. This infused oil can be used for topical applications, including burns, wounds, and sunburns.
  4. Syrup: First, prepare a tea using the flowers as described above. Strain out the flowers and mix the tea with honey. Store the syrup in the refrigerator for up to one month. This syrup is effective for treating coughs, colds, the flu, other viruses and lung ailments.

The Healing Walk of the Forest: Discover the Power of Phytoncides and Forest Bathing

by

Have you ever spent time in a forest and later noticed how at peace you felt? Did you notice how well you slept that night? Did you feel better physically? The trees and green plants of the forest emit invisible biochemicals called phytoncides that create a shield of protection around them to ward off harmful microbes, insects, bacteria, and fungal infections. When you are in a forest, you inhale these phytoncides and benefit from their medicinal qualities, such as a reduction in stress hormones, lower blood pressure, and a boost to your immune system. These phytoncides cause your body to increase white blood cells which fight off viruses and other microbes. The phytoncides are also beneficial in that they have anticancer properties, improve your respiratory and cardiovascular health, and even elevate your mood. The air of the forest can relax you and helps to calm nervous energy. It helps with insomnia. A two hour walk in the forest can produce enough white blood cell activity and a health boost that can last for days. In Japan they practice Shinrin-yoku, which according to my research translates as “forest bathing.” Could the Japanese, who have the highest life expectancy globally, be on to something? These phytoncides are part of what gives essential oils there powerful medicinal properties. There are thousands of phytoncides, but the most common forest-related compounds are listed as follows: camphene, pinene, limonene, myrcene, and sabinene. Forest bathing, hiking and camping are great ways to get a dose of these healing phytoncides, which aid in our physical and mental well-being. Depressed? Stressed? Feeling tired or worn out? Time to get out into the wild for a recharge! Getting outside, getting sunlight and breathing in that fresh medicinal air is an exceptional way to promote your health.
