Night or Day hunter? which are you

[black1]

I was wondering what most here do when hunting. I read most subs would submerge during the day to evade airplanes and from being seen and at night surface and hunt, is this somewhat correct and i was wondering what are some of your tactics and thoughts on doing this. I think from now on I may submerge and listen for contacts and plot course to follow and when it reaches night surface to chase down, get in position and attack either on surface or if needed at depth, what are your opinions on this. Also is there enough O2 for being submerged for a whole day? Thanks guys.
