yes you can buy different tanks for it. any tank should fit it fine (unless it's a tank made for hybrids which is rare) but the smok, ijoy, sense, uwell etc tanks will all work fine on it. The only thing is remember to buy a tank that takes coils that will work at your mods watt limit and also it's possible some tanks might hang over the sides. I'm not sure how big the 510 area is on the target
