Changing from 292 to 295

Aloha, took a 292 out that was working fine and upgraded to a 295, not sure exactly what transducer it’s paired with tho, square black rubber set in a fairing block was told possibly a 2K
292 was being used on LF, was told to use tap B setting with 295 ??
Recorder shows what I’d call pulses from the bottom of screen going up :huh
Need help with setting


Sorry first timer on a forum :sorry
 
Keikikai,
The FCV-292 is a dual frequency sounder, it's most common frequency pairing was 50/200Khz. However 28 and 88Khz were also available. The first step is to try and figure out what transducer(s) you have. A lot of times the FCV-292 had a label on the back that would indicate it's frequency pairing. If that's not available can you post the measurements of the face of the transducer(s) for us. If we know the length and width of the transducers, we can figure out what the FCV-292 was using.

Snips,

Thanks for the quick response, had a feeling I left some info out...
292 was 50/200... transducer was plugged into only LF side and when I removed the plug it only has 2 wires and red and a black..
Transducer is 6 1/4 inches long and 5 5/8 wide
 
Keikikai,
I sounds like you have a CA50B-12.
Its dimensions are 160mm x 143mm or 6.3" x 5.6".
If so, we recommend using an "A" tap setting for the FCV-295.
CA50B-12 was a 2kw transducer.

Thank you again, I will change the tap setting to A and try it tomorrow on the water
Will update later
 
Snips,

Changed tap settings to A, did a factory reset to start over at the dock, got very good picture up to about 20fa at 40fa start seeing feed back from bottom, adjust clutter and gain to get rid of feed back... moved out to deep/trolling still getting feed back down at 70-80fa
Have clutter up to 80% and LF gain at 3.5 also had to turn Tx pulse to long..
any adjustments/settings I should try and make while I’m out on the water
 
Snips .

I’ve been adjusting on the water the last 2 days, high and low clutter with high and low gains
Got into the tvg setting and adjusted that also and I’m still not getting good results when I’m out trolling 500-1000fa, I’m in the same area as friends that are marking a feed layer/bait
And also some big fish...

He also has a 292 tho with a different transducer, with my old 292 I’d mark that also with gain setting no higher than 3...

I’m can adjust to get great results when I’m in up to 50fa but one I go out deeper I’m not seeing anything and I also get the feed back on the bottom of screen

Should I use the same gain setting as 292 and adjust from there? I was told that this new units needed to be on the higher gains???

Also I’m trying to attach pictures and it doesn’t go is there any way I can send a different way??
 
Keikikai,
There are a lot of differences between the 292 and the 295. So the settings between the two will be different. Without seeing any screen shots it hard to say what setting(s) to change. However one setting I probably would advise against using is a long pulse. A longer PL will slow down the 295 TX rate.

Snips,

Finally got some pictures of my 295 that I’m trying up upload and it says it’s to big? Any idea how else I could send
 
I normally right click on the photo in windows and pick Send to a e-mail recipient. Windows will then ask about resizing the photos. This way I can quickly reduce the size of large photos. Then I don't send the new e-mail; I just drag the newly created files from the e-mail to a new folder on my desktop and cancel the e-mail. Now that the files are reasonable size I use them. It is just one method I use to reduce a photo down to size. If that doesn't work, I am sure there is a youtube video on reducing your photo sizes down.

This is the feedback I’m getting. I’m out in 700-1000fa water so I know it’s not bottom feedback, if I turn down the gain till it goes away I lose the little feed layer/bait
 
Keikikai,
Because it has a pattern to it, it is probably electrical noise.
What happens if you go dead ship with nothing else on?
I have seen inverters and battery chargers cause similar noise in sounders. Below is what inverter noise looked like on an FCV-1200, note the similar pattern.

Snips,
I had a chance to try it out on the water today and yes if I turn engines off it goes away.. Any suggestions on how to get rid of it??
 
had a similar issue check out my post - 295 with r99 engine interference and troubleshooting steps
the FURUNO forum staff got me straightened out
 
Teffy... thanks for replying, had a chance to read your post, you mentioned internal ground being removed... are you talking about the negative wire next to power???
 
im not sure that is the technical term but thats what i described it as. there are sheild wires (bare) in the transducer cable that you attach to the case area inside of where u attach the transduce cable plugs. i would check whether these wires had any affect connected or disconnected. even try leaving off or on the temp pigtail sheild wire


Try everything.

eng ground worked for me but still had a little bit of noise so i moved the freq down a bit since i have a broadband transducer.i have a capacitor also.

with my a non standard transducer (not in menu) the 295 needs more attention. in dirty green water i adust my tvg constantly to get a good return . not that is a bad thing the returns are incredible . i have a camera next to the sounder to take pics of interesting returns. i print the pics out and place in my 3 ring binder with my sounder notes.
