Garmin Gt54 Vs Gt56
I am planning on getting a Garmin EchoMap UHD 74sv unit. I'd get the 94 sv if there was room in my small center console, but there isn't.
In shopping around, I've noticed that some "packages" for the UHD 74sv have the GT54 transducer, while others have the GT56 transducer.
I assume (maybe I'm mistaken) that the GT56 is a newer model transducer? A little homework reveals that these two transducers do have some frequency differences from one another, but my one and only concern and question is whether or not there would be any VISIBLE performance differences between these two different transducers.
Informed and experienced input requested and genuinely appreciated. Uninformed speculation, not so much. Thanks in advance.

I had similar questions when I was selecting my transducer but found very little. There were a few YouTube videos, but they were mostly shallow water. I ended up getting the GT56 as it’s higher frequency provided more spread from my thru hull transducer. I haven't used it much, but so far very pleased with its performance.

It all depends upon what you are going to use it for.
TH GT56 & GT 54 will perform pretty equally in most uses, the GT56 has a deeper usable range, but if you are fishing in less than 75' of water, that won't matter. The GT54 has UHD clear view, which is great in shallow water (under 30') that the GT56 lacks, but the GT 56 will be a better performer once you get to about 60' of water depth. There is a reason it costs more, and that is because it uses somewhat bigger elements. I have the GT 54 and a GT 23 on my 23' CC, but we fish in saltwater in depths ranging from 10' to 300', and once you get deeper than 100' the GT 54 is not very useful.

Yes, the GT56 UHD is the newer unit and what is currently packaged with Garmin's ECHOMAP UHD units like the 74sv UHD,94SV UHD ,106 ULTRA etc.
Both GT54/ GT56 have Traditional CHIRP, Clear Vu and side Vu....
I have used both and the GT56 does have a bit sharper return for structure than the GT54...plus a bit deeper Traditional.
Also..
The GT54 has a 20' cable..the GT56 has a 25' cable.

Look up MG Marine Tech on YouTube... he did a pretty detailed review of both on the water. Has a bunch of EchoMap vids too.
My two cents... How often do you buy new electronics? Get the newest and best available of whatever you want to buy, don’t get last years model. I recently upgraded to the 74SV and have been very happy with it.

But public health
In an abrupt switch, the Centers for Disease Control and Prevention (CDC) changed its COVID-19 testing guidance to say that being exposed to a person with the disease doesn't necessarily warrant a test if you're not in a high-risk group or showing any symptoms, according to a Live Science report.
But public health officials are criticizing this sudden change, which a federal health official told CNN was a result of pressure from upper ranks of the Trump administration. Current evidence on COVID-19 transmission has not changed: The virus continues to infect many people who don't end up developing any symptoms, and who can silently spread the disease to others.
"These testing recommendations make no scientific sense, unless there are plans to demand isolation of all known contacts of COVID-19," said Krys Johnson, an assistant professor of instruction in the Department of Epidemiology and Biostatistics at Temple University in Pennsylvania.
It's not clear what percentage of COVID-19 cases are asymptomatic; some estimates say around 10 to 20%, but the CDC estimates about 40%. "If each of these people goes about their daily lives, this pandemic will continue to impact our country and daily lives for the foreseeable future, regardless of the advent of a vaccine," Johnson told Live Science in an email. "I actually didn’t believe it, for it seemed entirely bizarre,” California's Santa Clara County public health director Sara Cody said on Wednesday, according to the San Jose Mercury News. “The truth is that if you’ve been in contact with someone who is infected with COVID, you absolutely need to get a test.”
