The Karver KJ10 Winchless jammer allows course and fine tune without the use of a winch. The main line is run through the Winchless (which is based on the same 3 jaw, high load technology as the KJ Jammers) where the line can run freely. A finetune purchase can be permanently attached to the trip line which instantly grips the line as soon as the fine-tune is required. When the fine-tune is released the line goes back to course tune operation.
