Check the mounting location, check the cord connections, make sure the ducer is actually clicking when it is not working, otherwise either the unit or the ducer is going bad
No. St series from Raymarine are made for digital depth only, not fish finding and do not talk nmea. The only way to get that Garmin of yours to see depth would be to go from an ST40 nmea out to that garmin nmea in. Or purchase a nmea 0183 smart sensor and hook it to the garmin.
The transducer for your depth gauge will not work through an aluminum hull. A drilled through-hull transducer or a transom mount transducer are your options here.
You need to check to see if the depth sounder transducer is connected or functioning. It might be turned off, the connectors may be bad or the transducer is bad. I don't have the 498 manual in front of me but I think there is a test function under the setup menu. I'd check my connections (the usual suspect) then run that.
Garmin tech support is pretty good/quick. So don;t be afraid to give them a call.
It all depends on the type of boat and how you are going to be using the fishfinder. Here is my email: [email protected] if you want to discuss your uses further and if you want to purchase a transducer.
Sounds like the transducer is installed at the wrong angle or in such a way that it is getting a lot of air from something on the hull. If it is a transom mount, check that it is angled correctly and not too close to the motor or aft of some kind of thru-hull fitting that will cause turbulence.
Generally, that indicates air bubbles in the water under the transducer. If you have a transom-mount transducer, make sure the bottom surface is level or angled slightly down. If you have a thru-hull, make sure your bottom is fairly clean in that area.
A test bucket wont work, A 200 khz transducer will generally not work in anything less than 2' of water, due to surface clutter. If the transducer is working, you should hear it make a ticking sound.
When you got the 17000 foot reading was your range set to auto?
How is the transducer situated on the boat? Sometimes turbulence and bubbles from the hull can cause erroneous readings, including unrealistic depths, or no depth at all. Stop the boat and turn off the engin e and anything electrical to see if problem repeats itself. If it only crops up when the boat is moving then it is most likely the transducer location.
