Limpet Suite Product Sheet

Low Impact Minimally Percutaneous Electronic Transmitter (LIMPET) tags are widely used for cetacean tracking. LIMPETS were originally designed in 2006 for tracking killer whales. Since then, LIMPETS have tracked more than 20 species of whales and dolphins.

Users deploy LIMPETS remotely with a pneumatic rifle or crossbow anchoring two small titanium darts into the thin outer layer of blubber. The electronics remain external and, when the animal surfaces to breathe, the tag transmits data to the satellites. Typical deployment durations range from weeks to several months.


Wildlife Computers offers three separate LIMPET feature options: SPOT, SPLASH10, and SPLASH10-F.

LIMPET Accessories

Titanium Tag Darts

Wildlife Computers offers two dart sizes—standard and short. The standard dart contains two rows of three petals (six petals total) and is 68 mm long. The short dart contains a single row of three petals (three petals total) and is 45 mm long. Dart design is critical for tag reliability as the design dictates the implantation shock forces. For this reason, Wildlife Computers only warrants dart tags prior to implantation unless deployed with Wildlife Computer darts. Both sizes are USD $150 each and we require two darts per tag.

Dart Sterilization Packages

If you plan to use a gas sterilization system, these housings can be very helpful. The packaging consists of a tube and 2 urethane end-caps. When holding the “dart-tip” end-cap, the back end-cap and tubing can be removed. This allows you to easily screw the dart directly onto the tag without handling it.


Wildlife Computers supports the DANINJECT CO2 rifle for use with its LIMPET dart tags. DANINJECT, and our experienced clients, recommend model JM Special 25 with a 25 bar, 13 mm smooth barrel. You may need to call DANINJECT directly for this barrel option. Further information on this rifle can be found at: https://daninjectdartguns.com/product/jm-special/

Deployment Arrows

Both the air gun and crossbow arrows are available. Arrows are $75 and include a float and a deployment cup bonded in position.

Deployment Cups

Should you choose not to purchase the Wildlife Computers deployment arrows, deployment cups are available à la carte. Deployment cups are urethane cups designed to support the tag during firing. We have cups suitable for both crossbow shafts and air gun shafts. The cost is $25 and we recommend at least one cup per 3 tags be purchased.
