Default Noob on Garmin Fish Finder

Hello!

I'm looking at the Echomap Plus 62CV with no transducer and I'm going to pair it with GT-21TM. I mostly fish offshore not more than 200M that's why I prefer the 50/200khz.

My question is with regards to Sonar frequency.

Will I have the option in the sonar menu to choose LOW & HIGH Chirp since it's a 50/200Khz?

i'm a bit confused if this transducer will give that option because based on the description on their website, it only says "traditional 600W 50/200Khz"

Unlike the GT-23, it's says "CHIRP Mid-band (80-160 kHz)"

Does Garmin have a Chirp Low band transducer?

The GT21 does not do chirp for traditional sonar; it's just a dual frequency transducer. It uses a form of chirp for the ClearVu or as some other companies call it structure scan portion but that is not the same and is not as good at finding fish.

Usually you will see a chirp transducer advertise a range like 80-160 as opposed to a dual frequency that does either/or 50/200.
