I'm a little stuck... Click here to teach me more about this clue!

'flip' is the definition.
(I've seen this before)

'dive with a measure of caution?' is the wordplay.
I cannot quite understand how this works, but
'measure' could be 'end' (end is a kind of measure) and 'end' is found in the answer.
'of' could be 'o' and 'o' is found in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for go off the deep end that I've seen before include "See red" , "Be reluctant to enter part of pool" , "storm?" , "lose it" , "Flip" .)

I've seen this clue in the Sydney Morning Herald.
