Good news everyone!
I believe I've finally come out of my SR-71 induced stooper enough to make a somewhat coherent post regarding my meeting with G as well as what I've learned by playing with my unit (heh).
First and foremost, I wanted to thank @
THC SCIENTIFIC for the awesome customer service. From our meeting I can see that he really lives for these products and takes great pains in trying to get us all in proper working order. On top of that he most generously gave me a fresh set of AW batteries (the stock generic batteries just wont cut it for my Herc), as well as leaving me with a good half gram of pure gold in the coil, lol. But I digress...
Now that my Hercules SR-71 is up and flying, I couldn't be happier! Below (in no particular order because I have ADHD), I have listed insights, tips, and ideas for your browsing pleasure. Hopefully the following list will assist you in achieving enlightenment!
- As G stated, the Hercules is specifically designed so that you can reclaim the vast majority of your unused concentrates. While other companies make products which can be seen as direct competition for the Persei/SR-71 combo, NONE of them allow you to reclaim basically everything that isn't vaped... except the Hercules of course.
- If you disassemble any part of the core (other than the coil), you should always break the entire thing down and reassemble from the ground up. Don't be lazy and take shortcuts.
- The stock batteries that came with your Persei are not going to be good enough for the Hercules. AW is suggested by THC Sci, however I have also been getting great results from Efest 18350s. Word is that these are just rebranded AWs, and from what I've seen by 3rd party testers, the performance seems to be on par. I believe G took a set from Atom so he can test these out himself. From my own experience, I've been swapping between the AW and Efest's when one gets low on power, and I can't notice a difference unlike with the stock generic 18350s. Oh, I got the pair of Efest 18350s for $7.00 (+$4.00 for USPS 2-3 day mail) off of Amazon.
- DON'T run the Hercules on low batteries. While the AW's and Efest's have worked well for me until the Persei top cuts out, it is possible to have power drop off enough that you arent heating your oil enough to vape, but enough to loose viscosity. This was most likely one of my reasons for my leaking issue (this was with the stock generic batteries, NOT the AWs or Efests). Regardless of your battery brand, I just don't suggest taking the risk unless you don't really care. You can reclaim basically everything that leaks anyway!
- Try to use 99% iso. Yes, its available. Yes, in CA. I buy mine from my local Vons (it's Safeway brand iso). HUGE difference over 91%.
- Think of battery like like fuel in a car. Most of the fuel you use is spent getting the car up to speed (however fast that may be). Basically, you use way more gas getting to 70MPH (or 1,000,000,231KPH or WTF ever it is equal to for you non Americans) than you will traveling constantly at 70MPH. Same thing goes for the batteries and the SR-71. Most of the power you consume will be heating it up from a cold start. Once it gets going, you can lay off the gas and cruise for a while on the built up heat, while only needing short bursts of power to maintain that heat level. This is why finding the ideal temp for your load is critical. This matters for everything from vape density to how far you can stretch your meds.
- If you get whispy hits, its most likely one of three things. So before you fire off an email or make a post, try this:
- Check your batteries. Are they stock generics? Do they have a full charge?
- Try using the Herc without the black outer heat shield. Simply take it off then reattach the SS cap and mouthpiece. This will eliminate the possibility of an air leak.
- Make sure you have enough load in the coil. I've found it possible to get great hits off the oil reserve. That's great and all, but what you use from there needs to be replenished when you top off again. That means if you used .25 of your buffer, you will need to put .25 + whatever u were going to vape on the next fill.
- Don't overload. If you think its because of load, make sure everything else is okay before dumping more meds in there. Better safe than sorry and reclaiming.
- When using the outer heat shield, be sure to back the plastic piece out that holds the screen in the mouthpiece by a few threads.
- Always insert the SS cap into the chamber/heat-shield BEFORE putting on the mouthpiece. Don't leave it in the mouthpiece and try to screw it back on that way.
- Coil length should be cut to various sizes depending on what type of concentrate you are using. Its been covered fairly well so far in this thread, so I wont go into a lot more detail, however if we could get some user feedback for what works well with what length, that would be tits. To make this easy for people, the SHORTEST coil should be flush with the top of your ceramic rod (white, IDK about the other colors or if it even matters).
- Remember to COOL YOUR HERCULES DOWN. Draw air through it for a good 15-20 seconds after your last hit. This will prevent burning your oil and having it leak into the lower heater chamber.
- Also remember to store your cooled Herc sideways. If you have a very runny oil in there and or a fresh high capacity fill, consider slightly elevating the mouthpiece end to prevent runs into the mouthpiece. I actually use a styrofoam packing peanut as a "pillow" for the Herc, just for that purpose.
- Remember, storing it on it's side will mean your concentrates will... concentrate on the bottom half of the coil. Keep that in mind when reheating to get more hits. You may want to prime the Herc with that side facing up at an angle or even sideways.
- Every coil is slightly different in dimension and density. Because of this, how you properly hit your specific setup can be slightly or very different from someone else. This is being addressed by G, however in the meantime just keep that in mind when trying out stuff other people claimed worked for them. BOG's Herc seems to work great when its straight up and down. Mine needs to be tilted ever so slightly, and so on. Cutting your coil will also change this dynamic.
- To expand a bit more on that coil thing... Every coil has a different density. Basically one coil may hold more or less than the next. I suspect that coil saturation variations is a source of some issues for people. What I suggest is taking your coil out and loading it (completely) outside of the Hercules. This way you will be able to see the concentrate soak down into the coil. That will give you a good visual indication to determine when the coil is fully saturated. Once you can see the concentrate has made its way completely through the coil, try reinserting it and going from there. I found this way allows me to vape dab sized amounts of concentrates off the top of the loaded coil as well. Simply drop a dab on the top of the ceramic rod and have at it (short coil).
- Make sure your coil is properly seated firmly at the base of the upper cheater core. Push that thing down with a tool or a paperclip or something to make sure. If its not in complete contact, you wont get good (or maybe any) hits. That being said, I noticed that I'ts very easy to draw too hard and pull my cut coil off the base. I found to prevent this, I need to prime the coil by pulsing the button a few times before inhaling and then SLOWLY pulling Sherlock style. Imagine as if you were trying to get the thickest milk u can in a tiny bong. That slow. Once I know good vapor is coming, I can typically draw harder but Its not normally needed given how dense the vapor is. Also, this becomes more of an issue with the "thicker" concentrates. If your wax or whatever is rock solid when its cool, then all you will do is suck the coil up off its base if you don't liquify the load before drawing through the Hercules.
- If you don't have a (or don't want to) cut coil, you can load smaller amounts on the full sized coil by loading the BOTTOM of the coil outside of the Hercules. Simply take the coil out, flip it over, melt in your concentrate, then reinsert the coil making sure the concentrate side goes in first (facing down). I get good results when the bottom 1/4 or so of the coil is well soaked in wax/oil/etc.
- Be easy on the power. You should only really need a long power hold when the Hercules is first getting warm, so you can prime the oil/wax/etc. Obviously how long you need to press the button is going to depend on what you have loaded and how much, etc... however I try to go by this rule of thumb; If I can feel a good flow of vapor and/or I can hear stuff bubbling in there, the Herc is typically hot enough. From that point I let off the gas for a little while, occasionally getting back on it in short pulses (to keep the rod @ operating temp). I think most people have issues when they smash on the heat and just lay into it. Try this approach with slow inhales first. See where that gets you.
- I honestly think people should try hitting the Hercules more like a 2.4ohm cart. From there, expand and explore what this beat can do... but if you start small and familiar I think you will have a much easier time.
That's it for now, but I am sure I will think of more stuff to add as the day goes on, so check back for edits! Of course it takes steel to sharpen steel, so if you think I'm off base (or simply want to chime in on any of this) please do so ASAP! Were all in this together.
