The Compass Marine Pro-HST Heat Shrink Crimp tool:
This is a exclusive Compass Marine offering called the Pro-HST. It is a professional level tool for everyday use. It is a USA made controlled cycle ratcheting crimp tool specifically designed for heat shrink crimp terminals. This tool does not simply "squish" terminals to an oval shape it literally compresses them in a 360 degree manner just like the $1000.00 AMP tools do for insulated terminals. This tool is actually made by the same US company that manufactures many of AMP's crimp tools. This crimp tool is manufactured right here in the USA, supporting US jobs, in small lots. They are not comparable to inexpensive Chinese tools that may share some visual frame similarities.
