Stainless steel head dart tags (SSD) are for marking large fish such as billfish and sharks which can not be easily brought aboard. The tag head is specially ground and sharpened to anchor smoothly in firm tissue or muscle. All metal used in the dart head and wire is 316S grade surgical steel. SSD tags are made with the stainless steel wire covering the inside of the first 7cm of the marker. Some researchers prefer to have a stainless steel wire core along the length of the tag if there is a high likelihood of the tags being bitten by other sharks or predatory fish. These tags have superior legibility and integrity to our competitor’s products.
