  To see your fish tracks in 3D, Model 795 Acoustic Tags offer many advanced capabilities in the smallest acoustic tag commercially available. They are user programmable and work with HTI's Model 290/291 Acoustic Tag Tracking Systems, and together they offer an efficient means of remotely tracking fish in 3D with sub-meter resolution.
      > Acoustic Tag Spec Sheet
  Key Features of Acoustic Tags  
Sub-meter, 3D position resolution over time (e.g. every second).
Smallest tag size: 0.65 g in air, 6.7 mm dia x 16.4 mm long (Model 795 s Micro Acoustic Tag).
Individual tag ID with up to 100,000 unique codes available.

Acoustic Tag Specifications  
     Example of 3D fish tracking in the Sacramento
     River, California. The different colors in the fish
     track indicate different depths.

 Note: All tags operate at 307 kHz with an encoded signal.  Length, diameter, and weight may vary +/- 10%.   Life quoted is calculated based on operating parameters of 1 msec pulse width (PW) at 25°C and can be
 extended by decreasing PW and or PRI.

 > Model 590-series Hydrophone
  HTI hydrophones work perfectly for detecting Model 795 Acoustic Tags. See an example of Model 590-series Hydrophones deployed in a hydropower dam environment.

If your project is in a high-flow environment with flat surfaces for mounting hydrophones, we recommend HTI’s Low-Profile Hydrophone.

 > Model 595 Low-profile Hydrophone
Low-profile Hydrophone Similar to the Model 590-series Hydrophone, the low-profile hydrophone detects Model 795 Acoustic Tags. It was designed to easily mount onto flat structures. Its ping detection range is 170 degrees, as opposed to the 330 degree detection range of a pole-mounted Model 590-series Hydrophone. The low-profile hydrophone is ideal for flat structures in high-flow areas.
 
 > Model 690-series Hydrophone Cables
  Model 690-series Hydrophone Cables and Model 696 Armored Hydrophone Cables were designed to handle rugged aquatic environments. Compared to other cables, they allow significantly less noise from outside electrical sources. These cables are excellent for long term, deep water operations.
