Default Help choosing transducer for Garmin 741xs

Hi, everybody. I'm new to forum and spend several hours of searching and reading, but could not find the exact answer. Bought a boat from forum member which had old furuno green lcd fishfinder and i really cant read it that good. On my last boat i had lowrance 337 and i remember picking up structure and fish lot easier. Now with budget about 2K i think my best option is garmin 741xs. I'm fishing most of the time less than 200 feet of water. want to be able to see the bottom/fish at around 20 mph. Also like to do high speed trolling and scouting for new spots. Mostly still bottom fishing. What kind of transducer you recommend ? Right now i have transom mount, 525STID-PWD if i go 20 mph i see depth but bottom is not readable. Boat is 24' CC.

Welcome to THT and your first post.

To stay near your budget the Tm150M is probably a first choice..with the thru hull B75 a second.

Check out the post #25 on the link below and Tom is showing a video of the 547xs and Tm150 at 32 mph.

watched it, so is the chirp technology that makes it read so clear or just perfectly mounted transducer. i thought at those speeds only through hull would do it.

There are several factors to consider.

Generally with a tone burst system a thru the hull will certainly give better results vs a transom mount transducer of the same element type.

With CHIRP you have a bit better signal processing combined with a higher quality transducer.
I still prefer a thru hull as they will be running in cleaner water while on plane.
But as Tom's video shows...not bad for a transom mount.

Go one step at a time..try the Tm150.
Also..I can give you a 30 day trial..if you want to upgrade no problem exchanging it.

Late to the party, but I totally agree with the TM150. Airmar did a great job with this transducer, and CHIRP is definitely the way to go when it comes to sonar.
