Is there another 510 atomizer that the experts recommend that I can use for multiple hits?
Yes, there are a couple of options I think. You need to replace the oil as it's 'burned up', meaning it has to not only hold more but feed it to the heater in a uniform manner. We want continuous vapor production over time?
IMO the champ at this is no longer made (of course....). The ThermoVape EO cart holds half a gram or more and can dispense it in dozens of 'sips' or HUGE hits. I watched an entire gram be consumed in something like 32 consecutive hits. It takes iron lungs to do that. It's smaller bothers (Revolution/DART) held much less, maybe 1/8 gram but would feed it in a uniform manner. Now only available as used.
Still available as new are the Hercules and Trinity. Both from Delta 9. Hercules has been with us for several years and has been steadily evolving to fight the leaks that seem to happen when one is pushing production as hard as possible. The latest models are reported to be much improved but not problem free (yet). It does best on harder ('stable') goods, runny concentrate finds a way to leak out fast.
Trinity might be the call for you. It's 'brand new' (less than a month out?), holds .7 grams (.5 recommended routine fill) and seems to dispense well without leaks or problems. So far anyway. It needs thinner stuff (has to flow, even if very slowly, at room temperature). All the rage ATM is mixing in a drop or two of (very expensive) terpenes to thin it out enough to flow and feed and give a huge boost in taste. Another model, able to deal with thicker concentrates, is coming. You might want to wonder over to the Persei thread where both carts are discussed?
I'm enjoying Trinity, getting to know it, but still think 'load small and often' with DC attys more suited to me. I'm OK with V3 but really like V2s personally.
Here's a Trinity on top of one of our favorite mods:
And here's one with a small WT:
Trinity is reported to work by having a porous SiC 'wick'. That Silicone Carbide, very hard stuff, the stuff you make really tough 'sand paper' from since it 'cuts' most everything else short of diamond. Very heat resistance, you make containers for melting metals from it. You can grind it and 'sintered' into a single piece:

It's basically inert but has tiny holes that soak up' the goods on one side and hold it in front of a hot Titanium element on the other. As concentrate is evaporated away, more soaks in from the outside. Must have taken a lot of engineering/testing to get right. But, fed the right stuff (and CO2 oils seem OK......) it chugs ring along hit after hit after hit. Pure enjoyment with no maintenance between hits.
So the cart has super tough ceramic, Titanium, glass, some SS in the structure (not hot) and a couple of Silicone rubber seals to keep the concentrate in. No welds or glue (like in V3 over V2). I'm sure purists somewhere object to something in there, but none of the 'known evil materials' seems involved.
At $15 each, if you have a suitable TCR mod already, it's a cheap experiment?
