Running 2 Lowrance units

[Jerry]

I'm currently running a 350-A on the bow and a Global Map 2000 of the rear. It seems that when running both in manuel mode the rear unit does not mark fish ? Looking for poss info on what might be going on. The boat is 18 ft long are the transducers have a cross over problem?

Sounds like your transducer cones are colliding with each other. The only way to solve this is run one unit at a time or get a 192/50khz transducer for one of the units. Or only fish in water shallower than 16'. The new lowrance's are 200khz/50khz. This is still close to the 192khz so there may be problems with the new stuff and the old stuff.....

Sounds like a similar problem I had when running a Starcraft TP180 a few years back. I was told that it's a frequency issue and that the only way around it is to go the 192/50 route with different transducers. Other option is to look at a different brand for your second that runs at a different freq; or go the Pinpoint route (although it would be very expensive to switch out) with the networked system. It's seamless for solving the very issues you're talking about. Hope this helps.

I would recommend searching the archives. Very similar posts have been brought up many times, and there have been many accurate & valuable responses. You might search for khz or frequency. ?????
