Our shark finmount shapes are designed to position the antenna as high on the fin as possible to improve Argos transmissions. The robust “memory metal” antennas are custom-made using a nickel-titanium alloy. Antennas are available in standard and heavy-duty configurations. Attachment kits are included with the tag.
If you are studying large pelagic species that periodically bask, consider a Wildlife Computers towed tag. Towed tags are attached to the animal by a long tether and dart anchor. They are positively buoyant allowing them to float at the surface while trailing behind a slow-moving animal. Spot and SPLASH10-F towed designs have been used extensively on manta rays and whale sharks.
This video explains how Wildlife Computers SPOT finmount tags work.
