[QUOTE="jon holsenbeck, post: 594468, member: 47490"BTW, what is bottom lock?[/QUOTE] On reels? I haven't heard it called that but someone probably does, I heard it referred to as spool lock. These reels have no "clicker function" Where the "clicker" would normally be, instead that function locks line from leaving reel so you can break off, or pull with no drag. Popular with the JDM sold reels. Nice in that you don't have to change drag setting or wrap line around reel to break off a snag.
