Sorry Oliver I am not sure but you should be able to down load from the internet, I have the FURUNO H3000 and found it on the internet...

It is fairly simple if you get to the calibration page under set up but the manual should assist more I expect

Where to find the manual for this sensor setup?

Bill, it worked fine all last season but when i commenced sailing this season the paddle wheel was not functioning due to barnacles so I replaced it and it stated STW off, then you pointed me to calibration and then I found SOG was switched off, I switched it on on STW and TW and AW all worked fine.

Your 54 didn't come with a Paddlewheel. Probably when it was added, parameters were not guess.

Your 54 came with Sonic Speed.

Hi Bill, my issue was similar except my paddle wheel and sensor was ok accept the parameter associated to the sow was not activated in the H300 display, this then gave me SOW and correct TW and AW

As you may know, there are only a few values displayed on the B&G Hydra (2000-5000) that are actual. They are AWS, AWA, SOW, and Depth. All of the other values, like True Wind Angle, are calculated by the Hydra, usually using all of the actual values.

If your Speed Over Water (sonic speed or paddlewheel speed) is not working...or any of the other values, the calculated values will not be accurate.

Your issue is that the Sonic Speed is NOT working and the SOW value is not present in the calculation. You need to repair Sonic Speed, which is likely caused by sensors over 10 years old, add a B&G paddlewheel thru-hull, or something else. Check with a B&G rep for all of your options.

Have you tried entering into Menu and then setup and then calibrate and the entering a source? I’d had the same issue I think and found a source was not assigned such as SOG or similar

I got 2 issues with my B&G H2000:
1. The magnified Wind shows wrong values. It comes from extension processor. We replaced the instrument but still the same.

2. We stored on land for 12 month and did a refit.
When we launched the boat the boat speed through water does not show anything anymore.

Any help apreciated.

Thanks Joerg 

I have found the issue, the SOG was not activated in the H3000 set up. All is ok now, but it will improve more once I calabrate all parameters 

Thanks Paul

Paul, i, too, have had a failure of the sonic speed transducer but the new one - a much revised model Airmar I’m told - has been working flawlessly for 2 years.  If you do not have a BSP reading, you should check what the source of BSP is in the Settings Menu, likely under „system“  If it is the Airmar transducer, you should switch it to the paddle wheel (which is part of the depth and sea temp transducer, which is likely a dst200) and see whether you have BSP.   If you do, replace the sonic speed.  I would contact Stéphane at Pochon for this.  He may be able to get you a new one for free because the old one had known problems, but at least he will be able to tell you which type to get.  I’m not on the boat but can give you that info in late August if you still need it.   If you don’t see BSP with the paddle wheel either, you should check the other settings. Again, I can help in late August. 

You need BSP (or better yet, the drift corrected STW) to calculate the true wind direction and speed that you are seeing on the water - ie the wind speed and direction you need to make decisions whether to tack or gybe, for example, or to calibrate your wind instruments.  You could use SOG, but then you are calculating the TWD and TWS without any current effect and since the boat is sailing in the current, this will give you wrong info.    Even in the Med, current can make a significant difference.
