LMS350 50KHz Operation

[Paul Dickson]

I have a Pro V with the LMS350A in the back and an X-85 in front with the X85 transducer on the trolling motor. I have been considering a second transducer on the transom for the X-85 so the person fishing from the front when the TM is not down can see what is happening when trolling with the main motor, drifting or just running across the lake. That is easy enough to do with a switch but two 192KHx transducers on the transom would be a problem so would need to either add a 50KHz or Dual Frequency transducer for the LMS350 if I do this. Does anyone have experience with either the 50KhZ or dual frequency 50/192KHz transducers on this unit. I saw them on E Bay for less than $50 so the price is right.

Thanks for any info you can provide.

Used them for years. I have to say the 192/50khz transducer is very large, so large in fact I think it slowed my boat down 1-2mph from the drag. The system worked and I figured out a few very handy features using two sonars, one at 192khz and one at 50khz(both LMS350A's) Say you go over a school of bait fish and the 192 unit shows the bait fish, the 50khz unit is not as sensative to the smaller fish and you could tune it to not see the bait fish but show the larger fish feeding in the school. Not always good hooks but you could see them there. That I really liked. As far as shallow water performance the 50khz doesn't work very well. Normally you can run both at 192KHZ up to about 20' of water. At that point the units start experiencing crosstalk and the screens get full of artifact, looking like signals coming up from the bottom, almost like tall weeds. This sytem could be better, and that is why I'm goimg to 2 Pinpoint 7520's on my new boat. Just my 2 cents.......

Thanks Dutchman I appreciate the feedback. Will figure out what to do by the time the ice is out.
