i am wondering if there is a difference between the 200kHz cone angles between the dual freq ducer and the the single 200kHz. I just noticed that different 200kHz ducers have different angles, while browsing at lei-extras. I have a 110c with 200kHz ducer and thinking of up grading to the dual. I occasional try to use my humminbird 787 at the same time and the bird knocks out the 110c at about 30fow. hoping that the 50khz will allow both to operate simultaniously plus give me that wider angle when searching on flats. currently i use the bird for doing that but would like to use the instead since it has that big display. any thoughts would be appreciated.

The Lowrance 200 KHz transducer has a 20 degree nominal cone angle. The Lowrance 50/200 transducer is 12 degrees at 200 KHz, don't recall the cone angle at 50 KHz, but it's wider than 20 degrees.

thanks for the info. guess my next question would be do any of ya like that narrower beam or wider beam or are they both to extreme from the standard 20degree. I suppose the 12* would give good bottom seperation but would miss out on seeing some fish....hmmm...but could split screen i believe so could actually see more of the bottom while having enhanced bottom detail directly under the boat. does anybody run this system or know of any drawbacks? i typically fish in 5-30fow...this time of the year of course somewhat deeper than that. i guess i could leave my 20* on the transom and use it when want and get a ducer switch or just unplug one and plug in the other. any suggestions will be appreciated

It may not make much difference, but the dual frequency transducers are a LOT BIGGER than the 20 degree unit.

well i have a humminbird quadrabeam ducer so i guess im use to the rooster tails:bigsmile:
