SIGMA 3 Survival stands for Scout, Survive, Sustain.

These three words encompass our philosophy behind wilderness exploration and bushcraft skills. One of our core principles is the more you know, the less you carry. At Sigma 3, we will teach you all the primitive skills needed to survive anywhere in the world, with the least amount of survival gear possible. Having these skills will give you greater confidence in all outdoor adventures and the ability to go further with less equipment.


SIGMA 3 Survival School is known for its intense and completely immersive wilderness survival and bushcraft programs. Over the last decade, we have offered Survival, Tactical, Medical, and Preparedness programs of all types. However, our primary focus and goal is to train our students how to walk off into the wilderness with nothing but a knife and survive indefinitely.

We aren’t a school that teaches you how to get rescued when you’re lost. We teach you how to get lost in your adventures and shed your fear of the wilderness. With our standard training curriculum, which has been tested and proven to be solid for over a decade, you can be assured that the skills we teach you are the ones you need to know not only to survive but to thrive in the wilderness!


DIFFICULTY OF COURSES: All SIGMA 3 courses are rated on a 1-3 scale for difficulty, Level 1 being the easiest and Level 3 being the hardest. We truly believe that almost anyone, despite fitness levels or potential health issues, is capable of taking all of our courses. Some are very easy and laid back, while others are very difficult and more intense. Yet even in our most intense courses, we have helped people who never thought they would pass persevere all the way to graduation. If you have strong willpower and confidence, you have the ability to pass our courses. We are here to empower you and lift you up so that you can succeed and pass these generational skills to your family and friends!


Usually discounts are only given to small groups, but keep an eye out for sales if you're on a budget. We run great sales a few times a year when you can save big money. Contact us if you think you might qualify for a discount. We try to work with everyone, and if you legitimately can’t afford training, then we will work with you to make sure that you get that training. To set up a payment plan we have Affirm that can be used during checkout to finance your purchase.

CHILDREN: Children 8 years and up are allowed at most of our courses. Parents must attend with minors. Certain courses, such as the Instructor Course, SERE, and Urban E&E, are 18 and up only. Contact us if you have any questions about our child policies.


Almost all our courses offer a refund, minus a 30% cancellation fee. We have a cancellation fee, to discourage last minute changes in booking. We don’t offer any refunds with cancellations less than 2 weeks from date of the course. You can transfer your credit to other classes up to 3 years from purchase date. Many people look at the weather or have doubts about their ability to perform during survival training and get cold feet! Don’t stress about it. This stuff is easy with our help! We will walk you through it. Refunds aren't included in Survival Instructor program, there are no refunds for that program, but you can transfer your credit to other courses. And that credit is good for up to 3 years.
