What are the advantages / disadvantages of a fixed loop lanyard versus a slide lanyard?
Well, first, most T2FL (fixed loop) Lanyards have a single drop with one whistle and thus are “simple” lanyards that require no adjustment, etc. However, in other cases, being able to adjust (slide) the main knot can be an advantage. Please consider the following: For a fixed loop to go over ones head, it needs to be 27 – 30″ in diameter (depending on the individual’s head size and whether or not it needs to go on over glasses, etc.). 30″ is more or less standard, but let’s assume 28″ would work. That loop would contribute 14″ to the half length of the lanyard. The fixed knot would contribute about 1″additional. So, for a standard 21″ half length, from the back of the neck to the whistle ring, the drop below the fixed knot would be 6″ long. That length is not long enough for the whistle to be picked up and inserted into the mouth without lifting the fixed knot off the chest (and along with it what ever is on that leg, such as a counter, and on the other leg if there is one). That is us
