I've used
terrafin for the last 2 years.
I think it's reasonably priced at $100 for the year, unlimited access and it will help you find the general area of a temp break.
Also the last couple of years I've attended the Saltwater Seminar Series... for $45 you get a lot of "goodies" including a free Roffs report ($65). I always buy 2 tickets

I think the Roffs are the best available but very pricey.
I like to track the direction of the eddies in and around the canyons, Terrafins access let's you do that. The one thing I don't like with Terrafin is the color scale can change from day to day which makes it harder to track the water movement.
