In the Science on Scene section, page 19, it lists a number of apps helpful for Fire Fighter training including Knots 3D.
A few excerpts from the article:
It seems like just about everyone has a smartphone or tablet these days but few of us really explore the full power of these handy devices. Turns out these devices can be used for more than just Facebook and Google. A growing number of apps either have been developed for rescue services or have great useable features for us.
Knots 3D for iOS and Android is a cool, inexpensive app that shows 87 different knots in 3D animation, with more being added. Each knot and its uses are thoroughly described and alternate names shown. Just click on a name on the main list and the knot ties itself and allows you to turn it around to view from different positions. Speed it up or slow it down to stop action to help make learning a new knot a snap.
You really don’t want to be looking at an app right when you need that knot on a scene, but it’s great fun for drills and personal learning.
