I just use a 2 gb on my Lowrance and it will record for something like 24 hours. Sometimes the big cards (4 & over) cause more problems than they are worth, I say try the small first unless you get some more feedback, I look forward to seeing some pics. I wish more guys would post them, I love looking at them.

Cool. I will get a 2GB. I have a few areas I need to look at in SI to see what's really down there. LoL.

Mount it right over the trailer bunk. And if you do it correctly, you not only will better protect the transducer, but imaging and high speed sounding will function as designed...all in the spirit of avoiding screwhole damage.

The factory transducer will pop up as it comes from the manufacturer.

Humminbird can use up to 32GB SDHC cards with the latest updates installed. I find the best performance from the San Disk Extreme 3 Cards.

Thanks. Picked up a 8GB this evening.

Doug,

Here is the best view for my mount. the old transducer will come off. I may have to lower is some but if me your feedback. I hope to start the install this weekend. If any of Pros want to give there feedback please do so. I want to get it right.

Like I mentioned before I would mount one of the Poly Transducer Mounting boards so you can adjust without additional holes in the same location.

He has a mighty nice boat there.

question on sharing images via the ethernet cable from one unit to the other. I know both units have to be capable for instance if I want to share side imaging screens from an 898 on the console to a unit on the bow it also has to be a side imaging capable unit. But what about if I have one of the DI units on the bow like a 788DI, can I share that image with a 898 on the console? they are both capable of using DI, but one uses a different type of transducer to receive it.

There are two types of Down Imaging. Down Imaging Created with the Side Imaging transducer is different technology than dedicated Down Imaging so that data cannot be shared by Ethernet. Both have to be dedicated DI units or Side Imaging Units.

Went out for the first time with my 997 today. A few pictures I saved. The images looks real grainy. I need to figure out the basic settings. Any tips? The depth was on target all the time and didn't have any transducer issues.

Did you have the SI Enhance Sharpness Turned on? That's what the grainyness looks like. Sharpness is a great fish finding tool but does make the screen look grainey since it backshadows the strong returns. For Crisp images turn it off to find fish choose the level you need low, med, or high.

Yes I had it on. Will play with that later this afternoon when I go back to the lake. The unit is pretty cool. Thanks again

Doug, I turned off SI Enhance Sharpness and the picture is great. Now need to play with it and learn. Thanks again.
