It is also suitable for making noise when supporting your team at the stadium (if allowed by local laws). It is very handy, reliable, easy to store and carry on board, and its sound is <u>long-lasting!</u> Indeed, its battery can provide sufficient energy for 20 minutes of <u>continuous</u> sound (i.e.: the remarkable amount of <b><u>more than 250 starting procedures</b></u> including some general recalls.) It is also reasonably cheap: altogether it costs slightly more than 50 bucks. Roughly equivalent to only 4 Air Can Horns (one can do not last more than one regatta/match - when you are lucky ;-) The <a href="https://cad.onshape.com/documents/8cf90174e913a18765b7c6da/w/40df413f20304dad4cfcf7bb/e/37f0c93552f78937c692df9b">source drawing</a> on <i>Onshape</i> is parametric.
