at first, i started out fishing off shore without the aid of electronics. triangulation, a texas rigged worm, a marker buoy and an anchor. it got a little easier once i bought a $100 Eagle depth finder (with the old blocky pixels), but i still employed the triangulation method, and still do to this day, even with my basic Garmin sonar. i’m not knocking all the new technology, or those who use it, but i still enjoy the “old school” sporting aspect of the hunt. as far as the amount of time spent fishing one spot, i’ll do some fan casting on each of my holes until i feel i need to move on, usually 5-10 minutes if they’re not biting, more if they are.
