The reality is that most gear is not needed to hunt. As a recently married man with two young kids and a single income, I had to develop a priority list for extra money so I could hunt every year multiple times. I tired going into debt and it didn't work out for me.... Here is what I got. Every year I run down the list and use extra money on the next category.
1. Tags/licenses - I can't afford to hunt out of state on our current income, so I focus on opportunities in my home state and make the best of it. Side note: get off the band wagon and stop listening to influencer x, y, or z telling you about the 4 350 bulls he killed last year, it's bad for your mental health and you will never be able to do that and live the life you are living at the same time.
2. Reliable Affordable Vehicle - If you can't afford to put gas in your F350, do you even have a truck? I will take a reliable vehicle that gets decent mileage over a stereotypical outdoor truck. Most hunting requires long drive and fuel economy can impact the bottom line and prevent trips.
3. Weapons - Rifle, bow, muzzleloader. It needs to be accurate and reliable out to realistic ranges. Modifications can be made in the future to extend range and accuracy.
4. Packs - Finding game usually means covering country and carrying your stuff plus packing out meat. A good pack is a onetime investment that can be used for your entire hunting career. Get a good pack a stop trying to upgrade, they are expensive.
5. Boots - Good boots/shoes that fit your hunting style and needs will make the entire experience better and prevent injury. Very few people need $500 Crispi's, that's why this is low on the list. Honestly, Nike Free's are some of the quietest shoes I have used.
6. Optics - Optics are an enhancer not a requirement so they are at the bottom of the list. Everyone wants NL Pures but if you stay home until you can afford NL Pures, you still won't know how to hunt when you get them.
camo clothes, ultralight gear, sleep system, obsessive clothing layers, etc are all fluff and should be avoided until extra money is flowing.
