Reefmaster and Structure Scan
Posted: 20 Oct 2014, 14:59
Been playing around with this software called Reefmaster - Had it on trial but now got the full version....hours of fun!!
This is one of the scans taken the other week of a wreck in the bay....
On the left you have a map of the scan area, and the route i took - you can "play" the route to show exactly what was seen, where and when....
Then top middle is what the "normal" sounder produced - doesnt tell you much!! Then bottom middle is the down scan image directly below the boat.
On the right is the Side/Structure scan (white line is the boat, looking out to the sides)
The beauty of the side scan is that you can drop a way point anywhere you like out to the sides.... Doing that, the wreck is actually running at 45 degrees to the passes i made - Dropping pins all over the structure scan produces this..... A wreck approximately 120m long - far bigger than we first thought!! It also sticks up a good 20ft off the surrounding seabed, but more like 40 ft taking into account the 20ft of scouring around it. We did this at around high tide, i bet some of the rigging shows on a massive low water
Need to do a few more scans over the top of it, and run alongside it i think and build up a proper matrix of the area, but really impressed so far
Going to have to fish this spot, bet there are a few congers knocking about on it....
