Tuubooyinka wareegsan ee loo yaqaan 'spiral point' waxaa sidoo kale loo yaqaan tuubooyinka caarada. Waxay ku habboon yihiin godadka iyo dunta qoto dheer. Waxay leeyihiin xoog sare, cimri dheer, xawaare goyn degdeg ah, cabbirro deggan, iyo ilko cad (gaar ahaan ilko fiican). Waa qaab-dhismeed tuubooyin toosan oo si toosan loo sameeyay. Waxaa ikhtiraacay 1923 Ernst Reime, aasaasihii shirkadda NORIS ee Jarmalka. Dhinac ka mid ah godka toosan, geeska jarista ayaa la isku dhejiyaa si loo sameeyo xagal, jajabyadana waxaa loo sii daayaa jihada mindiyaha. Ku habboon in lagu farsameeyo godka dhex mara.
Astaamaheeda ayaa ah in god qaabaysan laga furo madaxa tuubada jeexdinta toosan si loo beddelo qaabka koonka jarista, taasoo keentay in jajabyada hore loo riixo oo laga saaro. Sidaa darteed, guud ahaan waxaa loo isticmaalaa oo keliya taabashada dunta godka dhex marta.
Maadaama habka gaarka ah ee looga saarayo jajabka tuubooyinka barta boolalku uu ka fogaanayo faragelinta jajabyada dusha sare ee dunta la sameeyay, tayada dunta tuubooyinka barta boolalku guud ahaan way ka fiican tahay tan tuubooyinka tuubada wareega iyo tuubooyinka tooska ah ee biibiilaha. Isla mar ahaantaana, xawaaraha jarista guud ahaan waxaa lagu kordhin karaa in ka badan 50% marka la barbar dhigo tuubooyinka biibiilaha wareega, taas oo si weyn u wanaajisa hufnaanta habaynta.
Intaa waxaa dheer, tuubooyinka boolalku waxay guud ahaan leeyihiin 4-5 gees oo jarid ah, taas oo sii yaraynaysa xaddiga jarista ilig kasta, taasoo kordhinaysa cimriga adeegga tuubada. Guud ahaan, marka la barbar dhigo tuubooyinka boolalku ku wareegsan yihiin, cimriga tuubooyinka boolalku ku yaal waxay ku sii dheeraan doonaan ugu yaraan hal mar. Sidaa darteed, tuubada godka dhex marta, haddii aysan jirin shuruudo gaar ah, tuubooyinka boolalku waa inay noqdaan doorashada koowaad.
