Gudbiyaha heerka submersible waa heerkulbeeye heerkul sare hagaya gaaska, kaas oo isku daraya dareeraha iyo wareegga habaynta calaamadaha ee sanduuqa isku xirka. Naqshadeyntani waxay u oggolaanaysaa dareemaha inuu la kulmo gaasta ku dhex milmay kartoonada, ka dibna gaaska u qaada qaybta dareenka iyada oo loo marayo tuubada dareenka. Alaabta cusubi waxay xallisaa caqabadaha la xidhiidha cabbiraadda heerarka dareeraha heerkulka sare iyadoo laga fogaanayo xidhiidhka tooska ah ee u dhexeeya dareemayaasha iyo dhexdhexaadka la cabbirayo. Qiyaasaha heerka immersion waxaa si gaar ah loogu talagalay inay daboolaan baahiyaha cabbiraadda heerarka dareeraha ee heerkulka sare ama dareeraha aadka u wasakhaysan. Sifooyinkeeda gaarka ah ayaa ka dhigaya mid ku habboon codsiyada u baahan cabbir yar ama dhexdhexaad ah iyo bay'ad leh warbaahin aad u daxalaysa. Mid ka mid ah faa'iidooyinka ugu muhiimsan ee cabbirrada heerka immersion waa awoodda lagu cabbiro heerarka dareeraha ee jawiga heerkulka sare. Farsamooyinka cabbiraadda heerka dareeraha dhaqameed waxay inta badan ku dhibtoonayaan inay si sax ah u go'aamiyaan heerka dareeraha heerkulka ba'an sababtoo ah xaddidnaanta dareenka. Si kastaba ha ahaatee, marka la eego cabbirada heerka immersion, dareemaha si toos ah uma soo bandhigin dhexdhexaadka la cabbirayo. Taa baddalkeeda, waxay la falgashaa gaaska ku jira dhululubada immersion, kaas oo u shaqeeya sidii xannibaad ilaalin ah. Habkani wuxuu hubinayaa cabbirka saxda ah oo lagu kalsoonaan karo xitaa marka lagu jiro xaaladaha heerkulka sare ee adag.
