Instrumentation

sonar

Wow? You actually went inside one of the ships? You're braver than I am for sure! ;)

I'm pretty sure Nick is right -- an early WW II sonar set, This must have been taken inside the sub chaser.

Wow Bakelite city!

AooGAH! Prepare to launch a full spread!

I agree with nick as well - sonar of some type

i would have so looted these ships of all the cool old stuff.

This is sonar, and yes, WWII era, this is making me wonder, could there be USN and USCG ships in this graveyard? Again, my idea of restoring one for a museum at the sight is an idea for honoring those that served aboard these now-dying ships.

Har du slike instrumenter Poseidon?

Ohhhh wow, fallout.....

" It's hard to tell through the Fog, Sir, But KONG ISLAND Must be DEAD AHEAD."

where is this exactly - love to tinker with some of the pieces if allowed on board

How do you know this is a sonar? ICouldnt it be a radar repeater? Vinatge surplus scanning sonars were rarely used on commercial vessels. Too much hassles with the hoist mechanism, packing glands to keep water out, transducer dome easily damaged if you strike anything (like logs) when lowered. The low frequency sub detecting scanning sonars werent very useful for commercial fishing, I never saw one on anything other than a Navy boat. Might be a sonar, just wondering....

who says it's on a commercial vessel? from what I gather both commercial vessels and navy are parked here. I may be mistaken though =\

i hate people that vandalize and loot UE sites. explore, take lots of photos and leave it the way you left it. if someone had "so looted this stuff" Mott wouldnt be able to share these shots with us. who knows what other treasures have been stolen from these ships.

Shoot don't loot! If less people looted we would have many more, interesting shots to look at. It always bothers me when the first thing people think of is their own greed instead of how can I preserve and learn from this piece of whatever.

Don't you think it looks like and old Radiodirection Finder??

looks like a pressure chamer for divers to come up slowly.

too small for that, look at the relative size of the dials/switches. Looks like an old ASW-style sonar

DEFINITELY Sonar. I have a history textbook from my college in my lap that has a photo of a sonar rig almost identical to that one in the book.

What you have here is a very badly treated indicator for a Navy SO radar.

So the mystery is over. R A D A R.

i believe that this is used to keep the ships tempeture for the engine at a average temp and not to high.

It's an ASDIC unit. The brits came up with them to hunt U-boats before the US got into the war. They would place them on merchant ships and anything that could float. A type of early passive sonar.

My guess is a radar display.

Well i would loot this. Why? It would look amazing in a museum. Imagine the history that could be recovered from these ships before the sea reclaims them!

this needs to be a wallpaper

Shoot! Then loot!!!! =)

This is definitely a US navy SOA or SO-3 Radar Unit. We have one exactly like it on the USS PT658 in Portland Oregon. I even can tell you what the switches are for. Underneath the PPI Display (the round window) is the Clockwise/Counterclockwise rotation toggle. I have been working on our unti to try and mock up a little rotating cursor and internal light as well as some "radar sounds" for when we display the PT Boat. Just FYI this is very definitely not SONAR! Jerry

I think it could be an early television set, the knob top left is channel up/down, bottom right is the volume, and under the display is the on/off control - hey well it could be

I think it is an early prototype of an i pod nano,probably only 56 k,before high speed wireless and 3 g networks.Just a guess...?

OH look it says SONAR on the upper left hand corner of the right side! ^_^

I don't know, this is ONE case where i say loot is better than shoot. These ships won't last long, and whatever is on board when they go will be taken with it. I would grab that sonar, and hold it, and know it's history, because once it collapses, no one will be taking pictures of it anymore, and no one will see it. it will be forgotten. Keep these boats alive in some way, you know? Besides, if you're crazy enough to board one, you deserve it.

It may be radar, but its radar Fred Flinstone-style. Check out those bakelite switches!

theres a difference between sonar and radar. Radar is newer then sonar and was invented around WWII

anyone think of the tons of asbestos and heavy metals these are likely to contain . not to mention the pain,fuel oil and other misc. nasty actors. no one wants to take responsibility for them now and with limited liability there are limits on what could be charged agains these companies for cleam up. I say start a fund a scrap drive and take this resource back full cycle and clean up the enviroment. just think of the mess we are making in our oceams. the gulf oil spill is a wake up call that its not ok to spill make messes and abandone junk in our waters then hold EPA super fund accountable for having not adressed this

Nope. It's an old mk1 radar set, built by Raytheon. They had a rather large dual band vaccume tube magnetron controller, but only put out 40 watts, which is why the screen was only 4 inches across. That other boat wasen't a "subchaser" or anything like that. They didn't have the 'walk wings" on each side of the bridge because it would have gotten in the way of fire control for the guns. They DID, however, have a need for them on harbor net tenders, (looking at the steel on the bow, I'd say it may have been a net tender) minsweepers, and YTB's (yard tub, big- used by the Navy or the Army. Yes, the Army had tugboats, more than the Navy did, believe it or not).
The black and grey buttons at the top right were to change the display color from yellow to red for night time use. No, they weren't green. The Mk 4's were green,and had a hoodscreen to look thru. The round control at the bottom right is the distance ranging switch, for high (12 miles) and low (2 miles). The toggle switch under the display was the power switch. it took 5 full minutes to warm up, ran on 125 volts DC power, and each magnetron tube only lasted 1000hrs before burning out.
I ws an ET in the Navy before I cross rated to OT. I really loved the chances I had to work on historical gear that still functioned.
