Humminbird Pirahna 160 Advice Please

[Whiskers]

Hey guys need some advice,

Had pretty bad rooster tail problem so I put a shield on but now can only get a reading under 4-8 knots once on the plan it just doesn't read at all?

Father inlaws does the exact same thing at speed but with out rooster tail or shield?

Oh and the reading was pretty poor without the sheild anyway.

Common problem? Settings issue? Location?

Any help would be very appreciated

air bubbles forming around the tranducer, same happened to mine

[madmullet]

ow and also you may find when on the plane the back of the boat lifts out of the water just enough to interfier......

air plus the signal from the transducer mixing together in like bubble or an air pocket trying to send down to bounce back = a very bad reading

[Whiskers]

Can I please get the other thread deleted please?

Air bubbles hey? So any idea what to do about them?

Can some one please clean this mess up as I really need help with the sounder question

edit your pic down in size... it may be like 3000x2000 piixels.... reduce it down to say 1500x700 for an eg

Elli Where are you

[madmullet]

one way that i found is transfer alot if weight to that side of the boat, like 4 people and then get on the plain and it should sit lower in the water thus given better bounce back. if this works move transducer lower on the tranom.

PM sent....(an extra one)

you may also find that it is due to being mounted on the port side, the starboard side is prefered due to less interference from the motor, and generally where the skipper is too therefore keeping the transom lower on that side

Need a side on shot but it looks to me as though transducer is facing wrong way. Do you have manual for the sounder they have detailed instructions of how to and where to mount.

Should look similar to this.

looks like it is kicking up from the water pressure and reading out behind the boat , angle it down towards under the boat a bit and see what happens ,

need a pic from the back of boat level with the hull and transducer if possible

A clearer shot from ebay looks similar to your transducer.

Definately kicking up and not sitting paralell with the boat as most manuals suggest. I have even pointed my Garmin one down towards the bottom to get a better reading at speed. Try levelling out the transducer and you should get a better reading
