Gyro binos are a near religion for top Southern California marlin fishermen. In fact, the best of the best often have four or five guys in them, each with his own quadrant of water to cover. A lot of daytime, finner swords are spotted with them by both sporties and plank boat guys.
I don't believe that they are all that common among the average So Cal tuna hunters, but some do use them.
We used them extensively down in The Baja, but much moreso for tuna and swords than marlin...There are so many of the latter down there, you don't really need them to catch good numbers of marlin. Tuna are a different story.
Marry a tall tuna tower (one of my great loves and something that I am simply miserable fishing without - it truly is "The Jaybird Seat") with a set or two of gyros and you will spot bird schools and holehead pods at downright unbelievable distances and this, in turn, will put you on some big tuna schools - and there are often dorado, wahoo and marlin among them - that no one else has seen. Some Mexican crew have incredible vision, but none could match what those gyros saw.
Ditto on locating big bird schools on the radar. As soon as you learn what to look for, your "range of sight" increases dramatically and you get the same results as you do with the gyros, only much further out. I had a screen in the tower and on the bridge and used it regularly to find the birds that, in Cabo at least, if you found, there were always fish on them.
As it is in many aspects of fishing, I don't consider any of this a "specialized, West Coast thing". As far as I'm concerned gyros, radar bird hunting, the right lures and spreads, teasers and bait and switch fishing and a lot more stuff that I write about in my books works anywhere and everywhere. One need look no further than our own JT here, to see vivid proof of that.
Yes, it all works; unless, of course, regional fishermen don't know the where and how of such things. And there is way too much of that, as far as this fisherman and author is concerned.
