The V8 tag is particularly suited for monitoring of salmon smolt migrations, and can be used to track large numbers of fish over large areas. The V8 offers an alternative between the V7 and V9 tags due to its higher output power and greater detection range. V8 coded transmitters send acoustic pings at 69 kHz that are infrequent and random about an average delay. This ping train includes an ID number which permits identification of the specific tag. The V8 can be detected by all VEMCO 69 kHz receivers. There are two battery options, the 4L or 4H. To control the characteristics of the tags, users can choose from one to four programming steps: Status (ON/OFF), time interval, acoustic power level (L/H) and nominal delay."@en ; skos:notation "SDN:L22::TOOL1156" ; skos:note "accepted"@en ; skos:prefLabel "Vemco V8 Coded Transmitter Tag"@en ; skos:related .
