Eagle tri finder

[CTD]

Hi, I'm still looking for the best fishfinder for me. Seems like most use a 20 degree transducer which has a pretty small view area. I was lookin at the trifinder, it claims 170 degrees, they claim 60 degrees for a 20 so it may be 3 20s together. Sounds good for me but the resolution is only 240x160. For those of you with a resolution in that area can you get a clear enough picture, for those with the trifinder how do you like it.<br />Thanks<br />Dave

I've had a FF with less resolution than that and it worked fine. More is nicer but it will do the job.

CTD<br />The vertical resolution is all that maters. The horzontial resolution just affects how long the image stays on the screen. I think we would all like to see 40 to 60 degrees transducer when fishing shallow water under 100 feet. Problem is to get a 45 degrees transducer must go to 50khz.<br /><br />The tri finder I at first thought would be a good unit but then after thinking about it I am not so sure. I think must send a pluse on the left transducer and wait for a reply, then send out a pulse on the center transducer and wait for a reply, then on the right and wait for a reply. After that can go back to the left. So it is a long time before send out a second pulse on the left transducer. To me that says both the fish and the boat must be moving verrrrry slow to draw a fish arch. I think if it worked good the top of the line unit would use it, but only place I see it is at the bottom of the line units.

Re: Eagle tri finder

That makes sense, if it were that good everyone would have it. Hope to hear from some people who actually use one. I had a chance to use my neighbors bottom line with a side finder and it seemed to work ok, Didn't catch a single fish that day though. Is the software in the fishfinders that converts signals to fish symbols very accurate or does it call every signal a fish.

CTD<br />In my opinion software about as smart as a newborn baby. It think any signal that is not part of the bottom is a fish symbol. Turn off the fish symbols and look at the raw returns, You can do a better job of telling if it a fish, bush, underwater tree branch or air bubbles.<br /><br />Fish finder can help you find fish or structure that should hold fish but has very little to do with catching fish.
