5 inch si verses a larger si question

[genec]

I hear a 5 inch screen will not show details easy, if I on a 5 inch screen set it on one side at 100 ft ,and you use a larger screen set at 100 ft on both sides ,how can the larger screen show the object better or bigger seeing that both have 640h or the same amount of dots in a inch?

also ,if I am in10 fow with scale set at 100ft,the unit is showing in the black part of screen what is dowm under the boat, if I move out to 50 ft will that leave only 50 ft of screen on the unit or do it condense the rest of the screen making the 100 ft in a smaller area?

SI set at 100 ft (one side) shows 100 ft of bottom....
SI set at 100 ft (both sides) shows 200 ft of bottom...and squashes all that 200 ft into the same 5 inch screen...

Setting the SI to 1 side (left or right) in effect zooms that image 2X ...

My wife always says it's not how big your unit is, it's how you use it...but I bought the bigger screen anyway!

rnvinc,thanks for the information on the first question, do anyone know the answer to the second question about when water colum gets deeper do it still give you all the picture and condense it into a smaller aera?

I think the answer is yes..

Gene, where are you mounting the transducer for the 798?

The depth wont matter, it will still show you what is there. As for showing what is directly under the boat is where down scan really comes into play on the split screen. This is why you buy the largest screen size that you can afford. When you start dividing the screen size up things get really small and is easy to miss things. I usually don't like to run wider than 50' both sides on the ss, and @ 40' you can really see the fish well. It dose not take that long to make another pass.

brushnjigs,I may not be clear on my question but it seems dept would have to matter because if I go deeper the picture of the water colum gets wider and wider until no room for the side view. Don I put it near the middle of the back in the cut out section near the drain plug. May try it tomorrow. How did you do at Buggs last week, planning on going tomorrow?

it doesn't matter if you are in 5' or 500', side imaging is still going to show you the same distance to the side, the depth of water does affect how much area is not shown on the side imagin directly beneath the boat. that is where your 2d or di comes in, like stated above buy the biggest screen you can afford.

Gene, one of the old Vets got sick so we put our last week trip on hold..Was supposed to be there today & tomorrow but got a muddy water report at the bridges and decided to put trip on hold again..We will be there when the water clears up a bit.
