I have a technical question I hope someone can help me with. I have a 17.7 foot tiller boat with a Fishmark 320 in the back. My bow mount graph need replacement. I just got the Spring Cabelas catalog and they are showing all the new electronics. Now I know why stores are selling the Fishmark 320s for $169, they added new models and upgraded the pixel counts again.
My questions are: If I buy another Graph with a 200 kHz frequency and a 20 degree transducer, how deep will I be able to fish without getting interference between both units when they are on. Does the interference start when the cone angles overlap or is there some other factor that causes the interference?
I busted out the protractor and assuming the transducers are about 16 feet apart, it seems that the cone angles won't overlap until I start fishing water deeper that I normally fish while using the bow mount trolling motor.
Wasn't terrible at a state park beach. Antelope island maybe. I wouldn't recommend it as a beach destination tho. Figured I was there, I'm getting in it.
The water looked and smelled disgusting with hundreds of thousands of birds sh*tting in there. About as gross as the Salton Sea. When I duck hunted there I didn't even want to touch the water.
It's kinda gross with the algae in the summer but I got in it anyway. Wanted to see the increased bouyancy at work. You can kinda tuck yourself into a ball and you'll just float with your head above water. When dry off you look diamond encrusted with the salt.
We went to the flats too. I dipped a tire on the rental car onto it just to say I’ve been there,but it was still pretty soft from winter melt. After seeing some moron in a BMW suv get dragged out of the muck I had no intention of repeating his stupidity.
