I am getting annoyed with the fact that I have to rely on my speed and FSD to get out of being attacked while mining/after being interdicted, and would like to know what the best defensive weapon is. What I am looking for is something that will get me out of a sticky situation relatively easily, but for a not-too-expensive price, as I am an amateur miner, and tend to earn money from completing transport missions, so money isn't the best for me. My ship is the viper MKIV, and my current weapons are 2 pulse lasers (gimballed) and a point defence. What I would really like is just something that could fire and/or aim automatically, and cause a decent amount of damage. Thanks in advance for any help.
Lasers are good against shielded enemies but a multicannon will do far better against hull. I would go with one gimballed pulse laser and a gimballed multicannon, just fire both constantly. You're only going to be fighting if someone attacks you first, so you shouldn't need to worry about running out of ammo too much.
Chaff is also very good as it will make gimballed weapons miss when targeting you, which keeps you alive longer.
