What do you put in it?

Wellies, spare tin hat , sandwiches. Oh , a bottle of whisky and a scotch egg for afters.....

stingrays! .. lots of stingrays!

A small port!

Now that that's out of the way. It really all depends on what ship you're flying and what you're fighting against. =)

A WDS-31 Serco Biowaste Disposal System. The rest of you may like crapping in a plastic sack, but biobags never appealed to me for whatever reason.

Depends on the ship and the activity.

Large Port:

Mining Beam MkII
Mega Positron
Repair Module
Proximity Mines
Jackhammer Rocket Launcher
Chaos Swarm Missile Launcher
Gatling Turret
Stingray Missiles

etc...

Things that small ports are better for:

Mineral Scanner
Rail Gun

Did you miss Plas Devs on purpose, TRS?

I feel the Plasma Devastator fits nicely in "etc..." ;)

Personally, I find it handy for mining and ... mines!

a microwave oven

Mining beams usually, or mines when trading.

Otherwise, I don't usually use large ports.

a leprechaun.

Chaos Swarms.

But, please learn HOW to use them, first.

I prefer a large Port with a Cigar, after Dinner.

I wasn't trying to list every large port weapon. I was pointing out that a large port has a better selection of everything except for mineral scanners and rails. (Although the low mass of gems are worth noting.)

Mines and Repair Modules are only available in large ports.
