SIGMA 3 Survival stands for Scout, Survive, Sustain.

Which encompasses our philosophy of wilderness explorations combined with bushcraft skills. The idea behind our philosophy is that we teach you all the primitive skills you’d ever need to know to survive anywhere in the world, and then use those primitive skills to supplement or replace your survival gear needs. Having these skills will give you greater confidence in all your outdoor adventures and give you the ability to go farther with less. The more you know, the less you carry!

SIGMA 3 Survival School is known for our intense and completely immersive wilderness survival and bushcraft programs. Over the last decade we have offered Survival, Tactical, Medical, & Preparedness programs of all types. But our primary focus and goal here 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 in general. With our standard training curriculum that has been tested and proven to be solid for over a decade, you can be assured the skills we teach you are the ones you need to know to not only survive, but thrive in the wilderness!


DIFFICULTY OF COURSES : All SIGMA 3 courses are rated on a 1-3 scale for difficulty! One being the easiest and three being the hardest. We truly believe that almost anyone, despite fitness levels or potential health issues, is capable of taking all our courses. Some are very easy and laid back, while others are very difficult and more intense. But even in our most intense courses, we have helped people that never thought they would pass, 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 and lift you up so that you can succeed and help carry these generational skills onto 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 where 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 setup a payment plan or group/family discount, then contact us today for details.

*We offer special discounts to military veterans. Contact us for more info on getting a military discount.

CHILDREN: Children 10 years and up are allowed at most of our courses. We prefer that a parent attend with the minor but if the parent absolutely can’t attend then we will work with you to make sure your child gets some world class training. 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.
The only courses we don’t offer refunds for are the Instructor Course and any Featured Guest Instructor courses we might be hosting. There is absolutely no money back on the instructor course but you can use that credit for literally anything you want if you decide to not take the course. We prefer that people cancelling just transfer their credit to another course and you can transfer that credit as many times as needed. Contact us if you have any questions regarding our refund policy.
