    Smallest compass archival tag on the market

    This miniature compass archival tag measures and records earth’s magnetic field strength and tilt in three directions, giving the compass measurements. Additionally it measures depth (pressure) and temperature. The logger is only 46 mm in length and 15 mm in width.


    DST magnetic is designed as a fish archival tag for geolocation studies, longitude latitude estimates and migration route tracking of fish and marine animals. It enables scientists to gain valuable information on migration routes and behavioural patterns over a long period of time. The tag can be implanted or tagged externally.

    Wide selection of depth ranges, from shallow to deep ocean

    Customers choose between depth calibration up to: 50 m, 100 m, 270 m, 800 m, 1500 m or 3000 m. The shallower the range the better the resolution and accuracy.

    Tag holder kit ensures easier and safer attachment

    A tag holder kit is available for the tags, to make the tagging process easier. It also increases the safety for the fish. See more under the accessories tab.

    User defined text on the housing

    For tag and release of animals into the wild the tags can have a customized text on the housing, for recapture purposes. This is especially important when the tags are used on commercially fished species, so that fishermen can return a tag with valuable data to the scientist. Normally there is a reward for return.
