The Rescue Throw Bags by Lehmar were developed especially for the rescue of persons as well as a technical aid. The biggest difference to ordinary heaving lines is that the second end of the line is equipped with an additional throw ball which allows the user to make a second attempt by re-casting the rescue line without having to store it in the bag again. Many other extras such as the Whiffle ball at the carry handle that improves throw distance and release, reflectors or holders for a glow stick make the Lehmar Rescue Throw Bag a well-engineered rescue device.
