Now days I usually use my
Cutter but my
Python is a dedicated Tritium miner.
The fastest way to mine Tritium is with SD/SSD, scan with PWA, prospect the brighter glowing rocks, don't ignore cores, some of them can have a considerable amount of Tritium in SSD deposits even if the core is not worth collecting. Don't forget to laser the rocks as well.
Any ship that is fairly fast and manoeuvrable can be used, I carry 2 SSDM's on both the above for ammo capacity reasons. resupply burns through tungsten faster than you can find it.
Take your time when you are SSD mining, pause for a couple of seconds after the chunks are ejected before firing the next shot. If you fire too soon you may only get 3 or 4 shots into each deposit but them few seconds pause can give you up to 7 or 8 shots into the same deposit.
