Issues Using 2 Sonars

[jwhadrava]

I have an LMS-332C and a X-100c. I have the X-100C on the front of the boat and both tranducers in the back. I am unable to get both units to work at the same time. They will work for about 2 minutes and then the 100C reads 2ft and the 332C reads 300ft or more. What should I do or change to alleviate this problem.

as long as the transducer are that close you will have the problem. If you can move one transducer to the front of the boat it might help your problem.

Is this real common or with some units. I have a buddy who runs an LCX-27C and an 332C and his work just fine. His transducer are actually within inches of each other and mine are at least on each side of the motor.

I believe if they are both using the same frequency you will have problems, I have an HDS8 and a 510C and if I use both at 200khz I get interference, If I put the HDS at 83khz I have no problems.

If they are both of the same frequency you will probably have interference like you are seeing now.

I have one on front trolling motor and one on the stern and will often see interference between the two.

Water depth, and bottom hardness have a bearing on mine.

Try changng the sensativity on one or both; that sometmes helps.

Or go to units with different frequencies....
