Default Which Garmin Transducer

I am purchasing a new Grady Freedom 307 and will be fishing in shallow to 75’ deep waters off the southwest coast of Florida. My dealer is recommending that I go with a transom mounted GT30 and a thru hull B60 or 171 (Garmin). I am leery of transom mount due to susceptibility to damage and am wondering why he is not recommending some of the more advanced ducers that are available. If anyone would be willing to share your thoughts on which selections would be best, it would be greatly appreciated.

thanks,
Ford

I use a 275 Airmar chirp in a pocket which has worked well for me. Just adding a Garmin GT51TM now for side scan (transom mount). The GT30 is cheap and considered a shallow water transducer. I wouldn't buy that.

Yes, I am wanting a side scan and would not mind having front scan, but i am not sure that is possible with this type of baot.

The MFDs will be twin 8612s.

Thanks,
Ford

The other transducer option for side scan besides a transom mount is the thru hull fairing mount versions.

And with a thru hull side scan mounting you have two options.

If the spot of mounting is less than 5 degrees deadrise you can use a single transducer..such as as a GT51TH.
But if the deadrise at the spot of mounting is greater than 5 degree then you would need to use a pair of transdcuers..such as the GT51 THP.

If the boat is trailered....sometimes fairing mount is not always the best option .
