I was recently told that PVC does not show up on depth finders,
Is this true?
If alage grows on it, I assume it shows!:rolleyes:

Thats the million dollar question...My best advice to you...If your going to drop pvc....Use landmarks on the bank to help you get back to it...I like to use two landmarks and line them up...It should get you in the right area...
I dropped alot of pvc condons and they all show up on my humminbird
Do you have the down scan?...Quote:

Our fishiding units show up as good as a tree underwater. Some guys don't like that but it's the case. Look on our website and you will find a side imaging pic of one of our Safehouse units. Clear as a bell with fish using it.
I was told by someone that PVC does not show up and thats way its used. The statment sounded false.. I guess I will just put a piece of PVC under my transducer to see.
The pvc that I dropped will show on a Humminbird 718, but it has a really weak return. The bamboo shows much better.
It seems to depend on the type of PVC, how it`s deployed (flooded or sealed) and how it`s orientated to the sonar beam; if it`s flooded (open ended and full of water) and verticle it can be hard to see. At an angle or raised slightly off the bottom should make them easier to "see'...a "Friend" recently dropped a cement block with PVC cement into the holes at varios angles into his Grand fathers private lake right off the rear of the boat and all we could make out was the block! Unit is an older Hummimgbird, but in 12 fow you`d think the PVC would have been visible...
being smooth and round scatters the sonar return. You can see them fine when they get covered with mud and algae. I put some in made out of 5" square PVC fence posts and sonar showed them like it was TV...just couldn't see much of the round "branches".
