Ólöf Hilmarsdóttir worked at shuffling fish-lines at Selatangi in Keflavík. She was washing her car with Undri when she got a brilliant idea.  It must be clever to use Undri on the fishing-lines.  She got permission to try the detergent and the result was obvious.  The fishing-line that ususally was really starch and tedious suddenly became soft and manageble.  The crew on Siggi Bjarna (the fishing boat she worked on) were very pleased with the result and Ólöf sais that she has no doubts, the catch has increased significantly even though it was good before.  People came to see the wonder with their own eyes and now many have tried for themselves and they agree with Ólöf.

Postitive experiments of three fishing boats emphasise that Undri works. 

The crew on Kópur from Grindavík has done systematic experiments with Undri fishing-line detergent and sprayed every other sector of the line.  Those sectors seem to catch a lot more fish.

Pétur Sigurđsson in Ebba KE claims that his catch has increased 50% since he started to use Undri fishing-line detergent.  Last New Year Pétur took his old fishing line, wich he had soaked in Undri, and added some hooks.  He located his line and the catch increased considerably.  Pétur thanks Undri for that.  He sais that it is an old saying, that new line catches more than an old one since the new one is clean and has all hooks applied.  When he used Undri his line became as new and started to catch more.
