> Model 490-LP Acoustic Tag Programmer |
| |
The Model 490 Acoustic Tag Programmer permits the user to program the Model 795 Acoustic Tag in the field. To activate, the tag is placed within the programmer’s magnetic coil. The programmer then activates an internal "switch" inside the tag allowing it to receive settings and begin transmission of the tag's signal.
Researchers can now program the various sizes of HTI acoustic tags in the field, in the lab, or in the fish. The Model 490-LP Acoustic Tag Programmer makes it
possible to activate and program Model 795 Acoustic Tags whenever and wherever you’re ready.
Each tag is placed within the new programming coil, which activates an internal switch inside the tag, allowing it to receive settings and begin transmission of its signal. It also has a new built-in detector that confirms the tag has been program-med. And the pulse detector LED light shows when your tag is active (or ‘awake’).
Besides being significantly smaller and lighter, it’s "in-fish ready" (meaning it directly connects to the Model 491 In-Fish Acoustic Tag Programmer). All acoustic tag settings are easily managed within TagProgrammer software.

HTI's Model 491 In-Fish Acoustic Tag Programmer activates and programs HTI Model 795 Acoustic Tags after surgical implantation (or gastrical insertion) into the fish. This programmer is used in conjunction with HTI's standard Model 490LP Acoustic Tag Programmer and a laptop computer. After a fish is tagged, it is allowed to recover from handling and surgery. It is then placed inside the clear acrylic tube filled with ambient water and passed through a magnetic coil to activate the tag immediately prior to release. This extends the life of the acoustic tag battery (compared to the usual activation of a transmitter at time of implantation), providing greater flexibility for field studies. |

|

|
The Model 492 Acoustic Tag Detector is used to verify at close ranges that a tag (alone or in a fish) is successfully transmitting. The unit verifies a tag’s pulse repetition interval (i.e. rep rate) by observing an LED light which flashes at the same interval as the pulse interval programmed for that tag. It’s powered by an internal
9 volt battery and signals when the battery reaches a low charge condition. A small probe at the end of a cable is placed in the water to detect the tag's transmit signal. |
