Okokuqala, sidinga ukunquma ukuthi yisiphi isibani esisifunayo? Uma isetshenziselwa ukuyibeka phansi futhi ifakwe ngebakaki, sizosebenzisa "isibani esingaphansi kwamanzi". Lesi sibani sifakwe ubakaki, futhi singalungiswa ngezikulufo ezimbili; Uma uyibeka ngaphansi kwamanzi kodwa ungafuni ukuthi isibani sikuvimbele ukuhamba kwakho, kuzomele usebenzise igama elishumekiwe, elinobuchwepheshe elithi “isibani esigqitshwe ngaphansi kwamanzi”. Uma usebenzisa lolu hlobo lwesibani, udinga ukwenza umgodi wokungcwaba isibani ngaphansi kwamanzi; Uma isetshenziswa emthonjeni futhi ifakwe ku-nozzle, kufanele ukhethe "i-splight spotlight", egxilwe ku-nozzle ngezikulufo ezintathu.
Eqinisweni, ukhetha izibani ezinemibala. Igama lethu lochwepheshe "linemibala". Lolu hlobo lwamalambu anemibala angaphansi kwamanzi lungahlukaniswa ngezindlela ezimbili, enye “iwukulawula kwangaphakathi” kanti enye “iwukulawula kwangaphandle”;
Ukulawula kwangaphakathi: izibani ezimbili kuphela zesibani ezixhunywe kumandla kagesi, futhi imodi yayo yokushintsha ilungisiwe, engenakushintshwa ngemva kokufakwa;
Ukulawula kwangaphandle: izintambo ezinhlanu eziyinhloko, izintambo ezimbili zamandla kanye nemigqa yesignali emithathu; Ukulawula kwangaphandle kuyinkimbinkimbi kakhulu. Idinga isilawuli ukulawula izinguquko zokukhanya. Yilokhu esikufunayo. Singahlela ukuyishintsha.
