What could it be?

[FunWithTreasure]

Anyone know what this thing in the right upper corner could be? At first I thought it was just a rock but I dont know. What do you think?

I think the fragment to the lower right was originally part of the larger object.

My guess would be a tree stump. RP

Is there a program or mathematical formula to determine the size of stuff imaged on the bottom with sidescan?

South end of a north bound alligator

I think you found Waldo.

Looks like an anchor....

 

[crzhors]

Heck,drop a buoy on it and dive it!

It would be nice to have a ROV handy don't you think ? When I find something ( detect something ) I drop my ROV ( homebuilt ) overboard and make sure what it is . I don't even have to dive to know . Cornelius

I also have a home made ROV but the current in the specific location is to strong.

'My ROV has three motors which can be used in calm waters . If the current is too strong I will tow the ROV behind my boat having only the motor that takes care of the depth working. All you got to do is to sail over the object . Cornelius (ps the picture of my ROV has been posted a long time ago on this forum but I show it again for the new-be's )

Anyone think this thing would be useful?

LS Morgan. That is just a toy . Avery small camera with no possibilities to have a clear picture . Very shallow depth . Mine is the same as a commercial unit . It is set up to go to 100 feet depth ( can go deeper with a longer cord ) . It has a professional color camera with infra red lights . Next to that there are two light sources ( one blue and one green ) . The cost of building one like mine is about $400 , and a lot of work . Cornelius

Back to the question at hand; it could be anything. I know this salty old retired clam boat captain who started using a hummingbird. He showed me a bunch of images he captured that he was convinced showed the sails of an old sailing vessel among other things. It helps to be a diver and know what a shipwreck looks like underwater. I have used several Hummingbirds and think they are awesome. However, sometimes you have to go down and check things out for yourself...

 

[pcolaboy]

I have a Humminbird 987c. Was the object still there on another pass? The reason I ask is because I've imaged a manatee sitting on the bottom that looks very similar to your object.

Otherwise, like the rest of the peanut gallery , I'd have to suggest dropping a camera overboard or just taking a quick dive. You never know.

See if this helps, a little image enhancement.

 

[Mackaydon]

To these eyes, I still believe the smaller piece broke off from the larger piece; the 'fit' is good.

I gave it another shot, best image can give you with my computer software.
Do I see a mound in the lower right?

I think it was 2 pieces as well. I dont know what it could be. I guess ill have to drop down there and see..Time to pull out the 7mm
