Plotter/Sonar unit HELP

Good Day.

I am replacing the a Garmin 541 on my 21 Key west Bay boat. I think I would like to stay with Garmin butt it has been 15+ years since I have researched features and capabilities.
Not concerned with anything over 100-125 ft deep.
Would like HiDef screen, not a touch screen
Unit that will deep hole shrimp

Thoughts on ClearVü™ and SideVü™ sonars, Chrip? 300w vs 600w?
Airmar transducer over the Garmin?

Whats the budget?

I have a GPSMAP 943XSV & the GT34UHD transducer & GCV20 sonar box.
It is now a hefty price but was cheaper back in 2020 when i got it all.
I can actually pull up to a dock & sidescan to see if any fish are under it. I am still learning it but it hascreally helped.
I am sure there are smaller set ups that may save you some money.

budget is pretty open and don’t want to kiil the piggy bank on things i wont use.

This has a ton of good info, should answer a few of your questions

I have a lowrance hook 7. It has chirp technology. I use it for deep hole shrimp and it puts me on the target.
Lowrance has a reputation for short lifespan, but mine has been solid for 7 years. I had to do a factory reset this year but it booted right back up. It’s budget friendly too. Just doesn’t have the high def screen. Fish don’t care if I have high def :joy:

I downloaded the Navionics app onto an iPad, as a backup plotter, and it was, actually, more accurate, offshore, than the Garmin we were using at that time.

I think it was around twenty bucks for the first year, and two or three bucks/year after that.

Navionics is a must have if your gps/fish finder is compatible. Love it.


If I were upgrading my Garmin 540 I would take a good long look at this deal next week.

If you get a sidescan unit, whatever the vendor (personally, I’d recommend Humminbird or Garmin), make sure its a megahertz transducer.

I had that sale paper around here a couple days ago but someone has already thrown it away. I remember a more expensive unit in there
Is that the one where you can see your lure?
I copy on the mega transducer.
Do y’all think it would help catching salt water inshore fish?


garmin is good at catching salt water inshore fishermen, thats for sure

Had the Garmin UHD 92sv with the GT56 transducer. Downloaded the Active Captain app along with the charts. Still getting used to the technology (especially the sidescan). I like it so far. Spend the money on the transducer!
