I have the obsolete 178c w/internal antenna which has a frequency range of 50-200 khz. I bought the 200 khz transducer PN 010-10249-00 w/depth & temperature capability when I installed it several years ago. I am pleased w/its features and it works very good in the bays. Unfortunately that transducer is also obolete but a suitable substitute would probably be the dual frequency 50/200khz w/depth & temperature PN 010-102720-00.

Keep in mind that w/the 178c you will need to buy the program chip w/Morgan City LA to Brownville to get the detailed map data of the Texas coast. I believe the newer Garmin models have the software built in but of course at a higher price. I spent several hundred extra $$ for the computer interface options such as the program chip reader to manage my waypoints and 110vac power supply to familarize myself w/the unit while off the water.

Good luck w/your choice.

looks like the 440s or the more expensive 540s is what garmin has now. looks like they come preloaded and have a different kind of map. i think its a satalitte image now.
