Default Help! Sounder producing odd, low-quality images.

Hi all,

The problem: sounder produces a very blocky, imprecise, pixelated image that looks like it's out of the 1980s. The sounder does correctly gauge the depth and correctly detects structure at bottom and detects anything in the water column, but the images of everything it detects are very sloppy and almost useless. What is the possible cause of this?

I have Raymarine eS128 electronics with Airmar B60. Boat is 2005 Hydra Sports. Electronics have been on for 3-4 years, don't know about the Ducer.

Thank you all for your help here on THT.

Following up on my own post -- is it possible that the eS128 is compatible only with CHIRP transducers and not traditional? That seems to be what this outline of specifications suggests? I had thought every display that was compatible with CHIRP was also backward-compatible with traditional sonar, but perhaps that is not the case? https://www.raymarine.com/view/index-id=12164.html

How did you upload one of my favorite games growing up onto your display? Asteroids for atari was always a blast, would be great to have the kids play during a slow bite.

You have the bottom fill checked in the menu,under sonar settings in the lower pictures.The upper picture you have the range and shift off.It also appears you have the A-scope turned on all the way on the right side.Capt.Mike

Thank you. I see from some of your other posts that you have long experience with various Raymarine setups. Have you ever seen the ugly, low-resolution, pixelated type images that mine is producing? Do you think the transducer might be bad or...?

Regarding the upper picture, (i) I will check the bottom fill; and (ii) the range and shift are on but I only snapped this photo while moored up to my friend's dock in very shallow water, which was throwing the reading off a bit.

Yes the A-scope is on. I will disable that as it wastes space. Thanks for pointing it out.

I am going to send you a private message regarding some purchasing decisions I am making.

Thank you.

eS128 is only compatible with Raymarine's mediocre CHIRP transducers, not with conventional fixed frequency transducers or Airmar CHIRP transducers.

eS127 is compatible with fixed frequency transducers. CP470 is required for Airmar CHIRP transducers.

Abbor, are you positive? That would definitely make sense and explain it. I suspected that might be the case, but Raymarine's information appears to say in some places that the e128 works with the B60. Below are some examples of conflicting information.

Specifications here suggests that eS128 is NOT compatible with B60; and is compatible only with Raymarine's CHIRP, like you say. https://www.raymarine.com/view/index-id=12164.html --> click Specifications tab, scroll down to "Sonar Options."

However the installation manual for the eS series doesn't distinguish between the eS128 and the eS127, and lists the B60 as approved. Maybe I'm misreading this installation memo and your theory is correct. I really appreciate it.

Follow up to own my post: Abbor is correct. Seller from who I purchased the boat upgraded the electronics but didn't realize traditional transducer was incompatible. I called Raymarine and confirmed that eS128 is not compatible with the Airmar B60. So now I have some choices to make.

Abbor - thank you for the help.

Abbor - the plot thickens. Today I found a CP370 box installed in the boat, which should make the B60 work. So, now I am confused again. I guess it could be either the transducer or the box or one of the cables that is not working correct. I would like to think that the odds are low that the problem is the eS128 - - but I can move the connection over to the other screen to rule that out, I guess. Any further thoughts on likely point of failure? I think I'm going to replace all this with CHIRP anyway

This miraculously fixed itself after a software update and a factory reset. Thanks for your help.
