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.

Does your phone app plot your GPS location over you map as you move around on the water?

Yes.  It will do estimated fuel consumption, distance and time to destination, heading, time to waypoint, etc.  

One of my favorite features is you can highlight a particular depth range where you want to fish and it will show you anything that fits your depth criteria on the map.

I have needed a new spot many times and looked on the app for something close by that looked workable.  Within a few taps, I have a few new spots to check out.
