That should be both coils together. When you add a second coil it splits the resistance in half, so if you have two 1 ohm coils it'll be .5 ohms total. That 1.7 ohm set up is pretty high for a mech mod but if it's high resistance wire then it sounds like one of the coils isn't firing. When I do dual micro coils with 8 wraps of 32g wire they're about 1.7 ohms each. But whether it's one coil not firing or just high resistance, your Nemesis won't fire it well until you get closer to 1 ohm. My personal favorite is between .6-.8 ohms. Just make sure your batteries can handle sub ohms. If you're not sure then just pick up the Sony 30 amp batteries and be done with it because they can handle .2 ohms for short bursts. They're the US18650VTC3 and are pretty cheap. If you order from Fasttech then expect to wait a month to get them, but you'll pay half the price.
