SI and HS transducer pics

|

Would you guys mind showing pics of you trasnducer setups? I'll take anything, I particularily have a Pro-V Lund, that I want to have both installed on. I am looking to see how some of you placements turned out. As in where you put the HS and where you put the SI transducers.
Thanks.

I would also appreciate these pics as I will be installing a unit soon. I know of someone who put theirs very close (laterally) the mid-line (against install direction recommendations) and has had good results. Anyone else experienced this? On a v-hull, it seems like a logical spot. You might also want to try a search in yahoo groups in the humminbird group. I have seen a lot of install photos there.

Guys, here is my photo... I posted this on the other thread as well. The si ducer is the big one just to the right of the main engine.
Terry - if you are referring to my boat, you are right, the ducer is a little closer to the engine than what the mnf recommends. I have had zero issues with it being that close, however. the main reason why i put is so close is to avoid any potential interference from the other 'ducers that i have mounted (didn't want to remove them). I almost always have the main engine trimmed up to some degree, but even at fully trimmed down, I don't have any interference issues.
When the kicker is fully trimmed down, i get a very small interference line on that side (doesn't block any crucial info, though)... Fix for that is to simply trim the kicker up about 2 inches. problem completely solved. I couldn't be happier with the ducer placement and subsequent SI images. can't wait to try out DI this year!!!!
It reads SI and 2d at 45mph, (with reduced detail obviously....)

This is a Lund install with HDSI and 2D transom mount transducer.

Jason,
Your main transducer,the one on the left "main" and SI I believe, is way above the flow line. Do you not use it for depth at crusing (on plane) speeds?? It looks like it would only contact the water when lightly motoring around or with the trolling motor. I'm Confused?

That's right. In this particular install, the boater wanted the SI transducer mounted high for protection, and a traditional transducer (which provides all the 2D sonar info) mounted in the traditional spot. This provides optimum 2D sonar at high speeds, and SI/DI at typical SI/DI speeds (i.e., less than 10 mph when that transducer is under the waterline)
This is the same type of install that occurs on many glass boats, except that the 2D sonar is provided by a through hull puck installed in the bilge.

Very interesting, Jason Thanks for the info!! 
So can both types of tranducers be mounted to one single 987csi?

Humminbird makes splitter cables, essentially you use the 2d elements of the high speed ducer and the si elements of the hdsi transducer. They also make cables for splitting left and right si to use independent hdsi ducers for scanning each side.

Denny, you would need a $20 Y cable, and a HS transducer (around $70). From what I gather it will automatically switch between the HS and SI ducers at the appropriate time.

Then DI uses the SI transducer?

Yes, DI uses the frequencies produced by the HDSI transducer.

What is the usual cost for a replacement SI transducer?????
Anyone know??

MSRP for the HDSI transducer for 1197/998/898 is $234:

So basically you are insuring your larger transducer with a smaller one.
$100 up front to add that second transducer to protect agains the "what-ifs" of damage due to hitting debris.
Jason, you may or may not know, but how often is damage to the transducer an issue?
I have checked some other prices for the SI 'ducer online, and it looks like you can get it for substantially less than MSRP. $175 on a quick check to amazon.com.... So you are paying $100 up front if you get the second transducer vs paying $75 additional later ($175 total) to get a replacement 'ducer (and only if you need to.. I would think that the majority of people who mount thier 'ducers low don't need to replace them due to damage??) I suppose it depends on the waters you fish, how hard/often you fish, etc...
Maybe it comes down to liklihood of 'ducer damage and/or liklihood of 'ducer failure/wear and tear due to regular use, in which case you'd have to replace the transducer anyway down the road.
Its been my observation that these transducers are built pretty solidly. Any insight on failure rates due to debris or other factors, Jason?
(Happy birthday, BTW!! )

Mike, I have read about SI ducer mounting in a few other forums lately, and have found several threads relating to this subject. To summarize my interpretation of these threads, I would say people are having trouble when they mount the transducer low and travel at high speeds (much higher speeds than you or I can travel in our boats). In particular, I have read posts about the bracket breaking from this, not so much the transducer. Of course, some people are concerned about hitting things, but in my opinion adding another $200 reason to slow down and not hit something sounds like good practice to me. Right now I'm leaning to a similar mount like yours. Have you ever run both of the transducers at the same time? If so, how bad is the interference?

As I understand it, the pin pattern on the Y cable is such that ALL of the 2D sonar always comes from the traditional (or through hull puck) transducer, while SI comes from the HDSI transducer. As a result, they will not interfere with each other.
Bracket breaking at high speed? How fast are these guys going? I've run my boat into the low 50s and never had an issue. I can collect SI, DI, and 2D sonar into the 40s (using only my HDSI transducer) without any problems whatsoever (example below at 41.5 mph).
Don't overthink it, guys. Do a good job rigging your transducer, then get out there and start using the units. If you're unsure or hesitant, invest in a professional rigging job. Feel free to drop me a PM for a recommendation on a high-quality, reasonably priced boat rigger.

Jason, now that I think about it, the reports of the transducer bracket breaking may have been regarding the 798 models. I believe the brackets are plastic??? From what I gather from the posts above, the 798 is the only model with a single transducer for both 2d & si?? For the others you mount two transducers? Or I am a way confused about the whole thing?

The HDSI transducer is a 2D as well like the one pictured on the Starboard side of the boat next to the O/B, If I'm correct?

Terry - The second transducer is optional... I only have one transducer for my 997... It functions for 2d, si and now di. For the guys that put their SI 'ducer up higher, they then add a second (2d) 'ducer for high speed bottom pickup.

What he said! 
Like Mike, I run only one transducer for all my sonar (SI, DI, 2D) readings. As others have mentioned, the second 2D transducer in conjunction with a SI transducer mounted high is an insurance policy against whacking the SI transducer on a log, rock, etc etc.
I'm a big believer in the KISS philosophy. Keep it simple and things will generally work out fine. One transducer for me. I can collect data at up to 40+ mph, and since my boat doesn't go all that much faster, my arrangement is just fine for me. It also provides me with lower up-front costs, fewer connections to loosen up over time, and fewer components to fail in the long run.

I also decided to go with just the SI transducer. I have a transducer plate mounted in the right area already, so I just went ahead and lined her up, and screwed it in last night. Planning on dropping it in the river tonight, and seeing how she works. Yesterday's weather gave me the itch bad! I can't believe how many options this dang HB has! I read the book last night, and will go through it again today, to try and get a handle on some of the finer points. This is going to be fun.

Oh, ya... BTW, don't forget to throw in a SD card so you can record all the cool images (and then share them with us!!!)
And record anything that's even close to being of interest... You'll have a blast reviewing those images back home on the computer. It's amazing what other cool stuff you see when you have time to stare at the images.
