will i go aground?

Okay I waited till I had a good headwind and the tide was running against me before I left the dock so far so good. As soon as I was out 10 minutes my newly installed garmin 740S with aairmar b45 transducer decided not to work it read up to 30' started flashing then quit altogether. It still reads temp and volts but not depth. Ive reset eveything gone through the owners manual, called garmin and still nothing. Anyone have any ideas?
PS im writing this from my phone in port townsend one finger at a time
Thanks
Nikolina

Re: will i go aground?

As to the question in the heading, yes you will go aground, at least at some time in your boating career. If you don't ever run aground either you're lying or you aren't really trying hard enough.

On the Garmin. I would check all the wires and connections to make sure nothing is loose. Trace from the transducer to the Garmin to make sure the wire didn't get pinched or broken.

If that doesn't solve it I would think first it's the transducer. Where did you buy it? Do they have a spare transducer you can try? If you can get one, don't bother wiring it just run the cable across the cabin to the Garmin, connect it and see if it works.

Re: will i go aground?

Been there done that! In my old marina 20' from my slip in front of a small cafe, no onlookers! HA! Anyhow been checking all the connections, nothing funny there. Heading around Vancouver Island the ground is harder than my head. Thought I might get lucky and someone would say that I need to refill the box of squelch, relplace the fluxcapacitor and swing a dead cat over my head three times while reading page 87 from Huckfinn. Guess Im not that lucky!

Sorry. No magic bullets for depth sounders but the cat trick will take care of warts. If you swing it 300 times it will even cure melanoma.

Does running a trimaran up onto beaches count as going aground? (ok, i have run across one reef, having to kick the crew into the water to push the boat across..) 'cos if it does i can relax...

Install a forward scanning sonar and know what is ahead of you, instead of what you are on top of.....

Re: will i go aground?

I have had a problem with my Garmin 441s flashing when I'm in shallow water. The Garmin tech support guy says to turn the gain to manual and back it off to about 7% - 10% so that the 500W of ping doesn't confuse the transducer. Hope this helps.

John

I know that this is true, but I've found that the damn cat's tail pulls off at around 200 revs... how do you get around this problem? Please hurry the answer because the black warty thing is getting bigger by the minute...

Cheers,

Jim

First choice, use a fresher cat.

Plan B, reinforce with Dyneema.
