location of oblivion rapid

[M C]

Good morning and compliments of the season, 

Is anyone able to verify the gps coords of Oblivion rapid on Batoka gorge ?.   T4a lists it at -17.9815 25.9113 but other opinions are that this point is between rapids 16 and 17 . Oblivion i think is number 18 .  

much appreciated,

Martin
