What to do next?

Firstly, thank you for your reply! But here are some questions:

Compound bow is far superior to the composite bow in the stable branch, and I highly recommend.

but where shall I look for it? In hunting stores I only find regular crossbows. Is it just my luck or they don’t spawn there?

The survivor armor is better than the ESAPI vest not because it has higher protection values, but because it has far higher coverage.

I understand the part about coverage percentage, but may I ask why is survivor armor considered having higher protection values compared with ESAPI vests? heavy survivor suit has 20 in bash and 24 in cutting while ESAPI has astonishingly 50 in bash and 90 in cutting. Or is it not correct to compare these numbers?

If it’s an old science lab (pink map marker) just bringing a keycard to open the door will get you in and from there the turrets are mostly isolated. If it’s a new lab (blue map marker), then i have no idea because I’ve only raided a single one before and it was pretty breezy.

Actually it shows as grey "l"s on my map, named “research facility”. Can I go into there safely without being killed by turrets?
