new update for humminbird side scan users

[shaggy1]

I figured I would pass this along since there seem to be several on here who use the Humminbird side immaging units. Humminbird just released a download update for their side imaging units that fix several issues and also adds a few more features. The update download can allow several cosmetic changes which is a minor plus, but the best thing is you can now split 3 different views and best of all,.... you can now view straight down with the side imaging, instead of just to the sides. I did the download and spent the better part of a day out on the lake using our 1197SI unit and I feel the new upgrades will really help with searches.

We did the update and found another use for our 1197C SI..... My marine enforcement guys are finding buoy anchors lost long ago... We also found a jet ski that sank about four years ago. The update was a real help in giving us added capabilities and a better chance for quicker rescue and/or recoveries.

I used mine the other day with great results. Really good upgrade.

Well, just when I thought I might know something about SONAR imaging, I see a "mystery."

The first image looks like pilings on the left side of the screen similar to what we see supporting a bridge stanchion (minor change in boat travel accounts for the S shape). I have no clue what the object is that you went across but if I was going to take a WAG, I would guess you went directly over a vehicle. It certainly looks man made but I would prefer to see it on one side or another, not split down both sides in order to make a better guess.

Is the second image a submerged bridge or rail track?

I'm stumped... Fill us in... What are we looking at???

The first one is old pilings at a closed shipyard on Bayou Bonfouca. The bottom view of that is a submerged boat, or what is left of it.

The second is in the middle of the Pearl River at Logtown. It is a wooden structure that was used to offload logs from barges. When the mill closed (1925ish) this was pulled out into the river. It is 8' high, about 25' wide and approx. 140' long. I have dived on this a few years ago.

The more angles you can get the better the picture it will paint as it has to bounce back. When the boat moves a bit the picture is skewed a bit. Kinda like a polygraph, you have to interpret you picture sometimes because you can't get enough, or the proper angles to see the objects. Sometimes they are plain as day.

Thanks for the update. The wooden structure at the log mill really had me stumped.

This is from a few years ago when I dived on this stuff. It had pics, but they don't seem to be there now.

Excellent story about the bones and vehicles...good equipment description and procedure details. Thanks for the link.
