hey. i got a humminbird 570 fish finder, without DI. i got it installed on saturday, and used it for the first time on sunday. it read the temperature and depth, but i couldnt get any more information than that. it didnt show the bottom profile, structure, fish, anythin, just a white line with occasional black vertical lines....

we realized when we are at full speed, the fishfinder is almost out of the water... however, the finder is already low on the transom, it actually hangs a little under the transom, maybe half transducer is below....

so, i will move it lower to prevent it from coming out of the water.... but besides that what could the problem be?? maybe the angle is not set correctly??

by the way, i had to route the transducer cable parallel to some electrical cables, but tried to separate them, and didnt use the same ties, in order to prevent a possible interference. i also let the transducer cable hang loose while the electrical cables are tight, so there is not much contact between them... i dont know if this works or not, but thought it couldnt hurt....

thanx!

The number one installation criteria is the transducer face has to have a smooth non-aerated water flow across face work properly all the time. If you send me two pictures of your transducer installation; one from the side and the other straight behind it from a low angle so I can see some of the hull bottom. I can critique it.
Angle could be an issue, hull location can be an issue too.

You didn't do the photo that shows some of the hull bottom, What is forward of the transducer has a bearing on performance.
What boat brand and model is it?

Does the unit perform properly at idle speed?

hey. the boat is a kingfisher, 17´ i believe, they say its from 1981 but the motor plate is from 1977 so i think the boat is also from that year... the unit performs the same (or should i say, does not works) when moving fast, slow, or completely stopped....

and, i just requested my friend the picture, when he gets home he will send it to me...

That looks good as far a hull smoothness. A better location is where it looks like one has been before to the right of the trailer bunk. Still put a little downward tilt on trailing end of the transducer. The Humminbird transom transducers are not as hydrodynamic as the Lowrance torpedo shaped ones are.

not an expert but with the fish finders Ive had, ive had the opposite problem, surface noise would put allot of clutter of the screen and out of the water it would find more fish than in the water.. ive sent sonar all over my backyard when i first got the thing and there are allot of lunkers back there depth reading would be all over the place ... even out of the water and in your driveway that thing should be buzzing low water depth 2 feet...

i mounted mine using an old trolling motor mount, took the motor out put a pipe in there attached the transducer to the end of the pipe ran the cable up the pipe to the unit and now i can lower it into the water a good foot below everything making noise, that got rid of the clutter and bad readings and made it more accurate but if i raise it up to the surface or pull it out of the water it finds lots of fish and stuff.

so i have no clue why your having the problem your having with it, id say call the toll free tech support and see what they say?

good luck

i remeber using my fishfinder little 110 buddy pordable as a fish finding wand... i had that thing out of the holded and aiming it all over the place looking for fish more than it was in the strait down position,, that thing was a 360 degree fish finding machine..

thanx for the input!!

the reason i put it there and not where i removed the old transducer, is because on the instructions it said to measure at least 15" from the end of the prop to the transducer... so right now the transducer is at 15", the old location was about 11" from the prop...

so, what do you suggets?? should i move it to the original position, and tilt it a little more downwards??

[Tony Monticelli]

well it does sound like you need to get it more in the water and off the surface, but it also sounds like you need to push buttons and play with the settings, increace gain/sensitivity, is the beam on wide or narrow,, does it split screan with bottom lock that gives you the best bottom views etc etc etc....

make something up as a temporary mount that you can move around and etc... just sticking it at the old spot might not be any good either if it starts getting clutter from the engine boat hull etc...

thanx tony!! this is the first fish finder i have seen, so i dont know how to adjust it properly.... i played with it a little bit last weekend when i installed it, but i increased/decreased sensitivity, and pushed every button and access every option it has, and i didnt get any improvement... thats when i began thinking the problem was more in the transducer or cable, rather than on the settings, as i couldnt get a bottom view, not even when moving only with the trolling motor or completely stopped...
