The V9 – 180 kHz transmitter monitors predation, movement and positioning activity of larger animals for up to two years.
The introduction of V9-180 kHz transmitters has expanded VEMCO’s 180 kHz capability to include longer life tags that can be used on larger animals. 180 kHz tags have been used widely on a variety of fish species from salmon smolts to arctic cod to various reef species.
Why 180 kHz Frequency?
The V9, operating at 180 kHz, is designed to work well in both fresh and salt water. Choosing this frequency enabled VEMCO to develop a small, lightweight tag that operates well in marine environments. Tags with operating frequencies greater than 200 kHz are less effective in salt water. Depending on the conditions of your location, the V9-180 kHz tag can reach 300 metres range.
The V9-180 kHz Transmitter Allows You to:
- conduct long-term studies of predator movements for up to two years
- track a predator after it has just eaten a salmon smolt that was tagged with a V4 or V5
- monitor movements of non-native fish species to understand their impact on the ecosystem and its inhabitants
Detect More Tags
Researchers can now tag and release many more fish simultaneously due to the detection capabilities of our new tag transmission systems – High Residence (HR) and Pulse Position Modulation (PPM).
180 kHz Positioning Studies
If your research requires detailed movement data, the V9-180 kHz has flexible programming options that allow you to conduct long term positioning studies using our traditional VR2W-based VPS (VEMCO Positioning System).
VEMCO Tag Activator (VTA)
The V9 does not have an activation magnet as is the case with larger transmitters. The tags are activated using a handheld unit, the VTA, that is exclusive to the 180 kHz line of transmitters only.
