hummingbird transducer interference ?

[huckfin]

Going to be replacing the 586c thats on the counsule with a 898. I would like to mount the 586 up front and have both transducer still transom mounted. Will both units function properly yet? I think I saw a way to run the 586 off of the 898 unit and was also wondering if anyone has any feed back on this.

There is some info here to hook up your 898 to a legacy product.

I would guess your going to get interference with both running off the transom unless for example you had 1 set to 83khz and the other 200khz.

Called tech at h/b no update available for 586. I'll check into the khz

settings. thanks

It has 200/83, same as your 898.

I would run your 586 with sonar set to 200/83 and use your 898 for side imaging and mapping. Which 898 did you get?

Or, you could sell me you 586 and i'll run it off of my trolling motor.

I got the 898c HD SI, Hoping to install this weekend. Thought about putting the transducer for the 586 on trolling motor, but that means the other half has to raise and lower trolling motor to use the locator. That being the case I would probably be better off just giving you the locator so as not to listen to the P & M ing.

On 2nd thought, the PtP is lower than i would like on the 586. Lowest i'd probably go is the 596 which is 4000ptp

Unless something has changed, the 898 ducer is always running both frequencies. You can't turn either 200 or 883 khz off. You can view either or both frequencies on the 898 through screen selections, so you could view 83 on the 898 and see no interference from the 586, which I assume runs the standard 200 khz. But the 586 will pick up the interference created from the 898 ducer. Try it and see how bad it is. There should be an adjustment on the 586 to filter out interference. Try it and see how bad it is. If you're only looking for a depth reading in the bow, it should be ok.

Yes, you can adjust the frequency you use on the 898cSI.

Ah, great question. I figured when i selected 83 or 200 instead of 83/200 that i was actually turning one frequency OFF. It is more likely that i am turning the VIEW off of that frequency. A call to HBIrd should clear that up.

No need to call HBird. Turn on both sonars at 200 khz and observe the interference (looks like rain on the screen). Then change the 898 to view only 83 khz. The other sonar will still show the interference from the 898 ducer firing at 200 khz.
