We have some wonderful tools available to us in these rapidly advancing times.

Have a look at the Geo-referencing tool in Google’s 3D program called ScetchUp8.

You can take your SideScan data and create a 3D model of it.  Then place it in the exact location in Google Earth and email to anybody on Earth.

lyk nice, maar bietjie ingewikkeld haha

So google has found a way to map under the water.

That's awesome!!!

John you are a legend in your own time... I have realised this weekend that the quality of your electronics needs to improve as your fishing does.. I know what structure I am looking for but have gove over known areas and the finder will show up a bump as opposed to a tree :alien

That is why you need decent electronics and a good finder like the DSI Lowrance Range

 

[Fishton]

100% spot on there Ryan.

Well, if I understand correctly, Google isn't mapping under the water, what you're doing is taking the records from your fish finder, then adding it into sketch up, which will then make a 3D mock up of it?

 

[Fishton]

That's right j- bay, it all starts with your SideScan sonar.

What is the accuracy on those? As a sidescan sonar is used for the plotting, it may be off by a bit.

 

[Fishton]

It ranges around 1 - 3 meters depending on EPE at the time of logging.

Not bad, does use the shadows to judge how high the object will be sticking out or do you have to measure it manually? Would really be nice to have a few spots mapped out with it, even if its just to see what the average bottom would look like.

 

[Fishton]

I use DownScan on my Lowrance HDS to get more details on the standing objects.

 

[braailegend]

Looks good, Im intrested, what type of sonars/transducers do those down scanners use? because most fishfinder will just return the shoalest sounding and then the bottom.

Speaking of which my Lowrance Elite 5 DSI is on its way from Fish Tec to  JHB as I write this.Cant wait to test it out on my Seadoo GTI!Will give it a test on Vaaldam over weekend before trip to Vidal at month end!Maybe I will be able to spot those monster barbel around the dam wall??

Best regards,
TAM

After seeing this and experiencing proper underwater equipment, it will be hard to fit a normal fishfinder. That is if I ever can afford something not oar propelled, haha
