The Tomcat is a dual function cap engineered to expand the capability of your Flowerpot F16 head. It doubles as a cap for the F16 but also has a 22mm Diffuser. 

We will refer to the converted F16 as "the Tomcat". It's purpose is to facilitate Troy's (from 420 Vapezone) technique for ideal extraction. 

This technique requires your first hit to be PURE convection and so the injector side of the Tomcat allows for this. The second hit would be a hybrid heated hit, this means that you can just flip the device over to the 22mm diffuser side and let it sit on the shovelhead (bowl) for about a minute, this will conduct enough heat to it to allow for conduction heating and then you pull air through it. This technique will "clean up" your bowl with a combination of conduction and convection extraction. 

This technique is only possible with the Shovelhead Titanium Bowl. 

F16 body and machined screen not included.
