3. Infrared all the way
Upgrade to Infrared as soon as you can–even if you don’t need to. It is a critical tool! Between making it easier to spot an animal in a darker environment to showing the organs of the animals (vital for organ-shot specific missions). When you upgrade your infrared, it also increases the battery charge life (meaning less time between recharges)
