using 2 fish finders

[nightowl66]

I have a Hummingird 757c on my dash and would like to install another cheaper fish finder on the bow and have both on at the same time. I have a Humminbird Xtreme 160 out of a older boat I though about using. I contacted Humminbird and they said they both run at the same frequency and will interfere with each other.
How do you go about finding one that will work and not interfere with each other?
Thanks for any help

Re: using 2 fish finders

It depends on the depth of the water you are using these locators in. I have a PinPoint at the box and an Lowrance on the console. There is no conflict but I usually fish in less than 30 feet of water and typiclly average 15. If you are in much deeper water then you need locators that don't operate on the same frequency.
