Nice images Abra.

And there is of course some questions.

Is the images taken by a towfish?
Have you been able to dive on the targets?
It looks like the wreck is on the right side from the anchor, or is it something else?
If you have identified the wreck and the aircraft, I, and I guess all the others would be interested in knowing what it is.

Beautiful pictures Abra!

Do you have the name of the wreck? 72 m is a big ship from my point of view. The longest (known) wreck in Lake Constance is the "Jura" with 46 meters.

YES,......

hi every body
i'm on my new home and my computer is connect again !!!!
magnetometer is interresting but in this search  there's lot of wreek and a mag take interference at a long distance wreek point
for this ship and this location a sonar may be a good solution.

Abra; Thanks for the reply. I am building a system 500 feet CAT6A cable, AMP/FILTER,CCTV,IR LIGHTS.

I have found slip rings on the internet for less then $30.00 US. So I will built a split ring reel to handle cable.  Enjoy Roddy

Abra; Your pix are super! I have set up one tow fish, and now I plan to set up a unit for 500 feet. Around Charleston SC. USA. the water is less than 70 feet to about 40 miles offshore then drops off to 3000+ Feet. I hope to scan some deep water wks. Hope you get out soon. Good Luck Roddy :)
