I use different ones at different times. I do like the brown one pretty well though.I will also say this. I like using the sonar networked more than I do separately. All that means is, that I see from both units the sonar from the rear transducer on the boat. It seems to do better than the one that is spinning as the trolling motor spins. I change up some though and take off the network feature from time to time and use the front one. One thing that alot of folks dont realize they need to do is, keep the two separate sonar units on different frequecies if using both.The two signals will both bounce off each other if same signal and give you undesirable results.Thats one big reason I network them to make sure that dont happen.GCF
