This is what happens when combining more than one technique to form a combination. These are the most popular / usefull combo's I've used.
Search hunt with ambush hunt - the spearo marks the separate ambush spots and moves from one to the other waiting on each place for about 20 seconds. Differs from a normal search hunt in that you stay at the ambush spots for some time before moving on.
Search hunt with cavities hunt - Normal search hunt with the occasional cavity check

thrown in. Can also be hanging around a canyon type structure during a normal search hunt.
"Let's not leave a hole unvisited!"
Tide hunt with surface hunt - pure gambling. Swim around in circles aimlessly and hope for the best. A in - out zig zag pattern sometimes work best.
Ambush hunt with cavities hunt - the spearo waits beside the hole like the method described above. This is usually applied when a fish is suspected to have holed up in a cavity.
I think that's about it ....... all the type I can think of for now. Anything else anyone can think of ?
Deep Dives, Big Fish, Good Shots and smelly feet to all !
