Hi. 1 : Can someone explain me why should I buy skill ( specialisation ) and module Deep core strip miner t2 ( see picture bellow ) ? And I see 320 m^3 and 480 m^3 but, the deep core if I understand, it’s like less efficient that regular strip miner !?? 2 : what is the better miner t2 or Strip miner t2 ? Thanks in advance ! and fail safe Ps : I get an exhumer ship ( Hulk ) see this picture : ![Capture d'écran 2022-12-16 06.54.22](https://global.discourse-cdn.com/eveonline/original/4X/a/4/f/a4f5fbf778e5d8826e7423128f68ae9187567873.png) ---

You are missing a couple of details in your comparison. Strip Miner I is used just like a mining laser - point it at any rock and it drags the same volume of stuff in regardless of the ore. Modulated Strip Miners are designed to work with mining crystals - fit any crystal and it will out perform the Strip Miner I _for the ore the crystal is designed for._ T1 crystals last forever, T2 crystals are consumed over time but have better bonuses. Deep Core miners are intended for mining Mercoxit - a useful ore for T2 manufacturing. They are less efficient than normal miners, but a normal miner can’t handle Mercoxit. [Mining laser details](https://wiki.eveuniversity.org/ORE_Basic_Ship_and_Skill_Overview#High-slot_modules). [Mining Crystal details](https://wiki.eveuniversity.org/ORE_Basic_Ship_and_Skill_Overview#Mining_crystals) There’s a world of difference between being able to fly a Hulk and knowing _how_ to fly a Hulk. ---

thanks my friend, in the beginning ( 2014 ), when i started in high sec hageken , i bought a exhumer and i make lot of money ! Its was simple because the Ore in high sec ( less skill ) is not like in null sec ( specialisation ). ---
