Technical Support

Need Help? Klein is always available and ready to serve
Klein was arguably one of the first in the industry to provide a 24/7 customer service program originally referred to as Niteline. This service was created to provide technical and sales support after normal business hours. Today Klein, maintains its commitment to "around the clock, around the world" service with well qualified technical and sales staff. We are currently servicing valued customers in 80 countries, and building upon international relationships to best meet the service needs of our customers.

Klein’s service technicians for Side Scan Sonar systems, Bathymetric systems and all related products can normally diagnose problems with a simple telephone call. If you need help, call us anytime.
