Predators' technology is extremely advanced, far beyond any other species currently known. The weapons we have seen them use, while generally modernized versions of existing tools, such as spears & blades, are only their basic hunting tools, not their most advanced or high-powered armaments.
In modern times people don't take machine guns on a big game hunt, they take rifles. It's the same situation in a different context.
Their other technology is seen to be far more advanced in its own right, such as the laser shown to effortlessly cut through 2000ft of ice in AVP,
being fired with pinpoint accuracy even from the depths of space. Even their video technology is extremely futuristic, they are capable of creating completely realistic 3D holograms by layering 2D images on top of one another, as seen in AVP, & even have sophisticated real-time thermal mapping on their wrist computers. They are light-years ahead of man in terms of advancement, having already mastered space travel long before we even learned to build.
