Navionics app.

[Downriggerer]

Well my son talked me in buying this expensive phone so I think I'll put it to good use. Thank you downrigger!!

Good luck!

Last year in Alaska I was coming in one halibut light due to a stuck anchor burning off a good chunk of my day and a raft of kelp that tore up all my gear.  I had a 45 minute drive back to "civilization" but I wasn't happy I was light a halibut.

I looked on my Navionics app as I was running back in for what kind of bottom we'd be going over as we were running, and also to help with my heading and time/distance to destination.  I rented a boat that doesn't have some of the luxuries my boat enjoys.

I saw a nice dropoff that was going to be right under where we were going.  As we got there, I dropped a herring that hit the bottom 1 time before a 60 lb halibut jumped on.  

I never would have put that fish in the box and my freezer if I didn't have the Navionics app on my phone.  I can cruise around on my phone, any time, save gas, and plan out trips and locations before I get anywhere near the water.  It's definitely worth it $15 a year for me.
