Feuer­wehrWilli tests a fire­fight­ing back­pack for himself & you. 20 litres of extin­guish­ing agent go in there and every­thing seems easy, does­n’t it?! You can see how long you can pump water with it (in fast motion) - a very long time. Conclu­sion: - well made - you can reach it for a long time - over 10m throw range - great addi­tion for oper­a­tions such as: espe­cially if you don’t have a water-carry­ing vehi­cle in your fire brigade.
