Thread: Running two sonar units

Thanks for all the information. I think i will just stay with one unit and just relay the information to my partner.
Thanks Agian

The transducer for the 898SI is about 4" from the bottom of the boat (that's right 4 inches) while the 595 transducer is mounted so that half of it is under the boat. I did not want my transducer for the 898 to be "in line" with the bottom of the boat; but, up high so as to be protected. Now, I couldn't and wouldn't do this if I did not already have the 595C which gives me lots of info including speed and depth. My 898 gives me speed, and depth as long as the 595 is off. However, AND FINALLY HERE IS MY POINT, if both transducers are on at the same time, the depth reading on my 898 could say I'm in 580 feet of water (for example) or 1 foot of water, when in fact I would be in twelve feet. So, I turn off the 595 and my 898 readings are perfect. Yes, since both transducers are operating at the same frequency they often interfere with one another.

Gansett,
Next time out you should try and turn on and up the Noise Filter menu in the 898c Si unit to see if it helps any with this.

Another option would be to buy the AS-Si-DB-Y cable and use the 595c unit’s transducer for the 2D sonar in the 898 unit. You would than be able to take the 595c off your boat if you wanted to.
