Default Need transducer advice

I am installing a Garmin 7212 with a GSD 24 sounder in my Bertram. I would like to get a transducer with depth/speed and temperature outputs, 1KW and 50/200 freqs. I have thru hull transducer now and will replace the existing one. I fish mostly deep water.;?;? Does it make sense to add a second transducer for a back up as the boat must be hauled to change transducers. Any suggestions?

IMO, if your existing transducer is in the "perfect" location, and you are getting good depth readings at all speeds even in shallow water, I would install the new ducer in the current location. (This assumes the first ducer can be removed without too much trouble.) There may not be too many areas of clean water under the hull. On the other hand, if you lose readings at high speed or in shallower water, there may be a better location for the new installation, in which case you might as well keep the first ducer as a backup.

The current transducer worked very well. I intend to install the new transducer in the same location. I am trying to get an idea of which transducer(s) make/model I should purchase to go with the electronics- GDS 24 which is 1kw,50/200, with temperature and speed. I have looked at the thru hull and the tilted element models and don't know which one works the best- These are older electronics so I would think there must be some opinions- Thanks Al

The only thru hull transducer with speed is a single element , 600 watt B744....not a deep water unit.

......................

For 1 kw transducers there is the flush mounted 3 element B164.
Also the B260 with a 22" fairing for larger boats..30' or so and larger...it can be pocket mounted on smaller boats.

Also..

The flush mounted SS264 pair..also 8 elements.
