Chirp III (TTV-170)

The TTV-170 and the TTV-290 series of tow vehicles are designed for hydrodynamic stability in most towing applications. The stainless steel midplate construction provides users with a rigid and stable platform to mount additional sensors. The high visibility yellow polyethylene covers are designed to handle years of use. These new and improved shells are more resistant to impact than earlier models, and are easy and cost effective to modify or replace.

  • The TTV-170 shell is designed to fit previous models of TTV-170 and is ideal for shallow water applications.
