30mm Coil and Banger Combo

If you’re looking to upgrade from a smaller banger, a 30mm banger is a great choice for a bigger payload. This banger and coil combo has all you need, minus the e-nail controller. I recommend to get the coil and banger all in one purchase; otherwise there’s a small chance that the fit between the banger and coil may not be quite right and may require some adjusting. As far as the accessories go, some cappers might be slightly too small for a 30mm banger, although this one should be the perfect fit. As far as inserts go, it comes down to preference, as the 19mm wide insert leaves plenty of room around the sides to grab with a tweezers, but some might prefer a slightly larger insert to hold the most massive globs. You can get it all here in one fell swoop with a discount and ensure everything works smoothly.

30mm Enail Coils vs. 25mm Enail Coils

Which is better: a 25mm coil or a 30mm coil? It all depends on your setup and preferences. I would recommend the 30mm to anyone who does larger dabs quite often. Although you can definitely fit some pretty huge globs in a 25mm, the 30mm helps distribute heat along the bottom more efficiently so that more heat is delivered more quickly where it’s needed. It also seems to keep the temperature more steady and less phased than the 25mm when dabbing. Another upside is that the larger 30mm barrel size is slightly easier to adjust compared to the 25mm, since the wraps are not as tight. Sometimes this can come in very handy if you end up getting a banger that is slightly different than your original.

Drawbacks Of A 30mm Coil

The drawbacks of using a bigger coil are fairly minimal. A 30mm coil takes slightly longer to get up to temperature; but once it does it stays more steady at that temperature while in use. One other small drawback to the 30mm coil is that it will use more electricity in the long run. There are also some concerns with mini rigs. The 30mm coil weighs a little more, so if you have a small rig with a light base on it there might be more chance of knocking it over if not careful. This is usually an easy fix, however. Simply adjust the position of the coil to point inward. In other words, the banger neck and coil neck should be aligned by rotating the coil neck to point back towards the rig. The coil neck will be resting against the banger neck if your banger is pointed away from the rig (and not cocked to the side). If your banger is off to the side then just make sure the coil neck is pointing back towards the rig. Check out this article for a handy diagram of how it should look. This is a recommended quick read if your rig is not the most sturdy and you have some concerns about it falling over on you with an enail coil. One other hack you can use is attaching your own heavy base to the bottom of your rig to simulate a larger rig and keep it upright.

Considerations For Mini Rigs Using 30mm Coils

A larger 30mm coil also weigh down a very small rig (or “banger hanger“). This can be remedied in most cases by making sure that the e-nail coil is pointing back towards the rig instead of away from it (see pic on this page). This keeps the center of gravity balanced on your dab rig and will help prevent it from tipping. Another handy piece of gear that helps with this is a drop-down adapter. One more important thing: please make sure that your e-nail coil cord is not in a place where you might snag it! Cats and e-nails sometimes don’t mix. It’s up to you to decide whether you are too accident prone for an e-nail or are not able to create a safe environment for your setup to reside.

Warning To Those With Limited Hand Function

Although the banger clamp offers the most secure yet flexible fit of your coil and banger, it might not be the best for those who have limited dexterity in their hands or chronic pain such as arthritis. The clamp prongs are pretty small, so it may be difficult to remove for those with hand or coordination issues. The great news is, as long as you have full functionality of your hands, you no longer have to worry about putting excessive force on the nipple of the banger when inserting or removing the fastener to your coil! Also, you can achieve the perfect fit, since the height at which the clamp is secured is now adjustable.
