Depth Finders/Fish Finders


-Marc V-

Question

Howdy Gang,

Would like to get some folks' opinion's on mainly one aspect of a fish/depth finder. I've been considering for some time getting a Lowrance x135 in black and white. I'm thinking that in getting this model it has 4,000 watt peak to peak power, and it's the cheapest one around that offers this feature.

I've heard that a higher watt finder will higher levels of detail (schools of baitfish) that depthfinders of a lower watt will not show. Is this line of reason true? If not, feel free to set me straight.

Another feature that I liked on this model was that you could change from a standard fish finder screen to a view that was similiar to vexilars, or marcums dispaly.

I'm just wondering if I could get away with a 2,400 watt finder, or even a 1,000 watt finder, and get pretty much the same level of detail that a 4,000 watt finder would show.

Probably going to be river fishing the most, and finding the baitfish would help my chances of finding the kitties, and other fish quite a bit easier.

Thanks for any input.

Marc

The only time that you will need more than 2000w is if you were fishing the great lakes or in the ocean when you might be fishing in much deeper water than we do in our lakes and rivers in MN. 2000 watts will be plenty for what you are looking for. If you want to get better detail of bait fish and fish in general then your best bet is to get a color fish finder, the detail and imagery of most colored units is much, much better than the b&w's. If a color unit is out of the question then get the x135, i've seen it in action and it is a great unit, I was skeptical at first that a colored unit would tell me what's going on under the boat better than the b&w, but once I got one I was very surprised at how much easier it was to tell the difference between baitfish and a pile of rocks or brush, and even the size of fish that I was marking.

Marc V,

More important then power is cone angle. Look at Humminbird to get easy to use units with multiple frequency/cone angles which will up your odds for finding baitfish and target species. Power of 4000 watts P/P will increase the ability of the wider cone angle to pick up smaller targets on the fringe of the cone. Just remember that a standard Lowrance cone ange of 20 degrees will only show a 3 foot circle below the tranducer in 10 foot of water. A similar Humminbird 60 degree cone will show a 9 foot circle below the tranducer which is how you see much more on a Humminbird then a comparable Lowrance dollar for dollar.

I checked out the Humminbirds. I've heard good things about them as a unit also.

One question, I found a Humminbird (767c) that has both color, and 4000 watt p/p power, but it's a dual frequency (200 kHz / 20degree @ -10db - 83 kHz / 60degree @ -10db). I've heard that on the shallower frequency, or one of the frequencies of a dual beam, that the unit will not be able to identify fish. And that dual frequency units are mainly for folks that fish with downriggers. Any truth to this?

Otherwise the 767c is in the same range as the lowrance with the same p/p power, and has a color display the same size.

Thanks for the help. Appreciate it.

I have the 777c2 with the quadra beam transducer. It has 20, 60 and 90 degree cones. All will mark fish. Most of the time I run it in the mode that combines the image seen by the 20 and 60 degree cones. Get a color unit. I really like my Humminbird.

I have always thought that the wattage output had more to do with the depth that you might be able to scan and to show finer detail requires higher resolution, not necessarily higher power.

That makes sense. Talked to a Lowrance rep at the "world's foremost outfitters" a couple weeks ago, and I think he was trying to tell me the same time, just wasn't clicking. Not sure if i'm just that slow, or if he wasn't explained all that great.

Think I'm headed toward a color screen now vs. the black and white. The Humminbird I have in mind will provide both the power, and the resolution. Should have both bases covered.

    • First snapper yesterday. It was looking for Leech!     Was that Leech?
    • Baked taters  grilled pork chops and Califlower  . Had better Califlower though. 
    • Sunset last night on Burntside lake.    
    • Just don’t know where else to put this ray of hope.
    • We get eggs from locals who have chickens.  The difference in shelf life between washed and unwashed eggs was weird the first time I heard it.  Months for unwashed; maybe a month for washed.   Farm fresh is a fair amount different than from the grocery store.  Bigger yolks and thinner shells are two of the more noticeable differences.  I had my first red yolk eggs a few weeks ago.  Kinda freaked me out but it’s no big deal really.
    • Nature is pretty rad.    I think it's cool the eggs can just sit there for some time.  Especially because it can get quite cold.   There are sometimes a dud or two and I first thought it might be because they froze before mom incubated them but they always kick off.  When I have done post mortem examinations of the duds they always have almost completely developed ducklings inside.  I've never found one that was just some yolk.
    • No mosquitos yet, plenty of flies the last couple of days and here is my first spider outside of the house!    
    • I’ve never studied it but I’m pretty sure she has to be full time incubating before they all start.
    • I have a bunch of people telling me to install a camera in the box and set up a webcast.  I know my parents would love it.  Especially my dad, who built the house.     If I ever get around to it, I'll post a link.
    • I wish I would have caught them taking the leap and deciding which mom to follow.  I saw them that morning and it looked like about 2/3 went with one and 1/3 the other.  Definitely some gansers in the mix too.     I've caught the leap once out of 5 years.  I track it pretty close and can predict within about 5 days window of when I need to watch in the morning for mama duck to fly down and wait.  I had it nailed last year but real life prevented me from seeing it happen.   It's interesting to me that the duck lays an egg or two a day and they pile up over the course of a week/week and a half.  But they all hatch on the same day.  Crazy.  It must have something to do with development kicking off when mama duck starts sitting on them full time.  It's cool that those first layed eggs just sit there in a state of suspended animation waiting for mom to start full time sitting on them.
