Who we are & what we do.

HTI is a dedicated group of scientists, engineers & techsspecializing in acoustic technology for fisheries assessments.

We’re your "local" global experts in monitoring fish survival, passage & behavior.

We design, engineer & manufacture acoustic equipment & software in Seattle. We also conduct studies, provide analysis reports & support everyday.

Driven by client needs and the feedback fish in fine-scale 3D. Driven by client needs and the feedback from our team of in-house consultants, HTI continues to evolve from our team of in-house consultants, HTI continues to evolve both technologies. Both are applied in freshwater & marine both technologies. Both are applied in freshwater & marine environments all over the world. environments all over the world.

Hydroacoustic Echo Sounder Advances – Releasing February 2012Our latest advance in hydroacoustics with Window 7™-compatibility completes our new monitor control boards with efficient raw data management and other asked-for features and upgrades.

New LY Acoustic Tags - Spring 2013The Model 795 LY tag is the latest addition to our L-series acoustic tag product line. Powered by a single lithium cell, this acoustic tag is ideal for longer term studies (possibly 2+ years or more depending upon needed resolution). This acoustic tag is designed for tracking predatory fish over extended periods of time and exhibits the same signal strength and resolution as other larger L-series acoustic tags. Like all HTI acoustic tags, the LY Tag comes with optional encapsulated PIT technology providing tag identification long after the tag battery has expired.

Autonomous Data Loggers - Fall 2013HTI's newest addition to this data logger suite will be a completely submersible, single-frequency receiver and data logger. Being completely autonomous and simple to use, this new data logger can be put in the water in the area of interest and left for the life of the rechargeable lithium battery pack. Employing the same technology as the Model 300-Series Data Loggers, it is also fully compatible with all HTI acoustic systems. By virtue of the proprietary tag encoding, like all of HTI acoustic tag system, it is immune to tag collisions. Comparable to a VEMCO VR2, HTI's autonomous data logger can simultaneously detect and identify literally hundreds of acoustic tags at the same time in the array.
