Lowrance Transducer- Are they the same?

Does anybody know if it is the same transducer for the HD 5 as it is on the Lowrance 510 C?

According to LEI they are the same.

Thanks

Is LEI the manufacturer? I cannot remember what was on the package.

lei is the mfg of lowrance.

NBCrappie, I have a X510C. I just put transducers on the back and trolling motor, with a switch to change front to back. Hope it works , but I have not had a chance to try it out, due to weather and high ,muddy water. The x510c will use the HST-WSBL as well as the HD5X, but it is only a single beam transducer. I think the HD5X is dual beam capable, so I think if you use the transducer from the X510C you will only be able to have single beam coverage. Someone who is more knowledge than I am may be able to give you more information. I believe the X125 and X135 also use the same transducers. Those units,however, are not color. Hope this helps and I hope you like your X510C.
