Wonderful continent ya got there, Fish stealing bull sharks and Stealth Croc's!!! Makes me want to go diving..... Not! lol.
But seriously though, Wonderful images and as a Navy Aviation Anti Submarine Warfare Operator, with quals in accoustics and imaging radar, yes I would agree that the uneven surface kinda acts like the facits (sp?) on a stealth aircraft and scatter the Hi Freq signal. Shadows on stuff that absorb are the only clue they are there. The classic sailboat shot in the website shows a strong shadow of the forward sail but the sail itself is much less visible due to it's fabric nature.
I would assume with the lower freqs we will loose some resolution? Looking forward to my install of my 997c, Waiting for my twin Thru Hull Transducers and high speed kit to arrive at the dealer.
My new toy the 997 is going in: http://www.sonorantruck.com/detail-2003 ... 96334.html

Dead right you would not want to dive in the freshwater Fitzroy River, but our oceans and coastline offers fantastic diving.

Back to the Fitzroy River again next week for 3 more weeks so we will see what we can see under the surface again.

This image shows the exact point of impact of a 3 foot barramundi by a 5 foot freshwater bull shark.

that's what I call a lucky strike John!

Not lucky for the barra , it came to the boat without a tail.

that's even cooler than locating a target with the SI and dive there to see what it actually is!
I guess the barra tasted well even without the tail
Tight lines John

JOHN, SIMPLY AMAZING. I JUST VIEWED THAT SHOT AND WOULD LIKE TO HAVE PERMISSION TO USE SOME CROCK SHOTS IN SEMINARS. I DO MOST DEALER SEMINARS USING YELLOWFIN ON LAPTOP. I WILL MAKE KNOWN THAT THE SNAPSHOTS COME FROM THIS FORUM AND FROM ANOTHER COUNTRY. I NOW HAVE ANOTHER REASON TO NOT BE IN SALT WATER, OR NEAR COSTAL WATER. IF THE PEOPLE AT SEMINARS COME TO THIS SITE THEY CAN ENJOY SNAPSHOTS VIDEOS AND A WEALTH OF KNOWLEDGE. FOR ALL INVOLVED THIS SITE HAS BECOME MY FREE TIME LOCATION. AWESOME,AWESOME,AWESOME.

Yes by all means, just acknowledge where they came from and that will be fine. Did you check my latest post with the croc, stingrays, baitfish and barra.
The predation shot was very interesting as I was fighting the fish and saw sharks on the screen. I felt the shark (and I think with the barra in its mouth) hit the shaft of the bow mount Minn Kota and the barra went limp and I just reeled it in the last few feet. In my minds eye, I thought that the tandem just had some much momentum that the initial impact obviously occurred next to the transom where the transducer is mounted, but the shark came from behind and from the side and kept going and hit the Minn Kota at the bow.
These things really are amazing.

This is an interesting action shot. It shows a 13 foot saltwater crocodile in the instant it lifts off the bottom of the river to swim away. You can see with the shadow of the tail is still in contact with the primary return but you can also see the primary return of the head is away from the corresponding shadow, so the only way I can interpret this image is the croc was fully on the bottom and was in the act of pushing up and off the bottom with its front legs as it was about to swim away.
And sometimes you do

Some things you see, this time in down imaging, you do want to see. These are Australian barramundi around the 3 foot length.
