whats ur fish finder?

my lowrance hdi finally crapped out on me, it had gps maps built into it. looking to replace it with any recommendations??

Or one of these??

am shooting thru hull which i understand makes a side view unit(which i don`t think i need?) not doable?

I switched from Lowrance to Garmin a few years ago and have found them to be way more user friendly and I have been very happy with them overall.  I went with the Garmin Striker 7plus SV.  The striker doesn’t have the built in maps.  I believe the Echomap version does.  I also have the striker 4 plus on one of my other kayaks.  Overall, I really have liked the Garmin.

I have the Hummingbird Helix 5. I bought the navionics chip for it for mapping. I have been pretty happy other the Hummingbird power cable issues which are a constant hassle. I think my next one will be a Garmin.

Like nobaddays, I've got a Garmin Striker 5DV as my primary and a Striker 4 as a backup spare back in the truck. Neither has maps but I always run my Marine charts and Lake maps on iBoating on my tablet and have it on my phone too as a secondary backup. Both FFs have GPS and all the features for tracking, saving your tracks, creating routes, waypoints, etc. I've run the 5DV for 13 hours non-stop and my 8aH battery was still at 12.3v.

I will attest to the impressive sonar resolution of the Striker 5DV from a trip last summer. Anchored in 25 feet of water on a lake in dead calm conditions fishing salmon roe for arctic char. I was changing to fresh bait and dropped a single egg in the water about the size of a BB gun bb. 0.177"  Shortly the egg showed in the transducer cone about 5 feet under the boat. I watched that single egg drift to the bottom of the lake 25 feet down. From that day on I was pretty much assured that if I wasn't seeing any fish on the finder, there really wasn't any fish down there. And that was shooting through the Lowrance-ready plate on the hull.

I would say that having GPS and waypoint creation on any brand of FF is the most valuable feature bar none. Whether you are trolling/drifting or just stop at a spot that has a great bite, being able to return to that location is paramount to repeating success.....well, uh, most of the time.

I like running my charts, salt and fresh, on a separate device - actually both my cell and tab have it when on the boat. If my FF ever dies, I still have full navigation and charting and even my track to follow back home if needed.

I've got the Humminbird Helix 5 G2 GPS DI with Navionics maps.  Really like it. 

thanks for replies, appreciated! ......am going with a garmin echomap uhd 64cv with coast mapping. just ordered!
