Default transducer ticking / now not

I used to be able to hear the transducer ticking. Now I can't hear it anymore and I loose the bottom when up on plane. It is a shoot through. Could it have gone bad? Or could something else like a ground wire cause this?
I know I need to give more particular info. I'll get that when I go down to the boat tomorow morning. I just figured I had to start norrowing down instead of putting it off longer.

Thanks

I've never owned a transducer that didn't ping.

First make sure you haven't turned the gain all the way down. I would do a rest on the unit to be sure.

If that is not it, then my bet would be something is wrong with the crystal in the transducer or poor power supply to the 'ducer. Check the connector well. Depending on your unit you might be able to get the pin-outs and you can check for power on the pins of the head unit.

Process of elimation from there - you know anyone with a 'ducer that you can connect your head unit to?

According to a warning that Airmar used to have on their website (but I can no longer find after their last reconfiguration), one should not hear any clicking. Supposedly if one does , it indicates the T/D has already been somewhat damaged and internally loosened, usually as a result of being activated while out of the water for more than 60-90 seconds . At the time this seemed a bit odd as many epoxy in their T/D's as shoot-thru's. Perhaps it is a lot better to use the mineral oil cannister type shoot-thru ? A call or e-mail to Airmar may give you a more definitive answer. Do not put your ear anywhere near the T/D any time it is activated. You will likely not hear anything at all but may experience excruciating ear/brain pain., like a spike suddenly shot thru your head. Voice of experience from long, long ago. .....(sigh).

Is it a glue in shoot thru or is it one of the transducers with the fluid well like the P79 or M260 where you epoxy in the housing, then fill up the well with either mineral oil or non-toxic engine antifreezebefore putting the transducer element in? If it is the well type, check your fluid level, you may have a leak, especially if you used 5200 to attach the housing and mineral oil for the fluid (now a no-no per Airmar, but origianlly a recommended combo).

Thanks for the help. I have the p-79. I'll have to check the fluid level, didn't think of that. If it did leak out I hope I didn't kill the 'ducer.

If the transducer is working you will hear it transmitting, (Clicking). transducers don't fail to often in my experiences. It could be a cable issue or a dead transducer. Best thing to do is borrow or purchase another transducer, plug it in and hang it over the side of the boat in the water and see what you get.

I checked the fluid level and there was fluid in the there. I added more so that when I put the 'ducer back in it over flowed so I know that it is full. I installed it in the spring or early summer. So now I'll check the connections and check the warranty.

My Airmar clicks louder when the frequency is on 50 then 200 when I can barely hear it.

Well, I called Standard Horizon and they said the problem is in the unit. Forgot to mention it is ff520 for the cp1000c. Sent it to them got , got it back in about a week and half. It's hooked up again and is doing fine so far.
Thanks for the help everyone.

If the transducer is working you will hear it transmitting, (Clicking). ...
I can understand why lots of people think that, seems to make sense, initially. Human hearing, if perfect, is 20 cycles up to 20 thousand cycles (20hz-20khz). Some people in rare instances can hear a dog whistle at around 22khz. Perfect hearing is a thing mostly in males, age 17 to 19. After that it’s all down hill, i.e. hearing loss.

A transducer is pinging away in the range of 50 thousand cycles (50khz) for a low frequency transducer. That is way, way above anything a human (or a dog) can hear. Don’t even think about trying to tune in a transducer pinging at 200khz.

So if you are hearing a noise coming from your transducer you are hearing something other than the transmission…unless you are Superman with ultra-sonic hear abilities or something like.

Well, whatever the clicking is when it clicks/ticks it holds the bottom. When I didn't hear it, I had nothing. Now after I got it back, the clicking is back and the sounder is holding bottom again at all speeds.

Thanks for the info. I sent my plotter and FF520 back yesterday to SH. FF520 stopped working the last trip out of the season and the CP1000 looked like the inside of the screen was cleaned with a somewhat dirty cloth which left a few streaks. I'm sure SH will have mine back in no time.
