Retro-look depth sounder

Here's a modern version of what all depth, or echo, sounders used to look like. What was old becomes new, eh? This is a lot like what echo sounders looked like when I first went to sea. I haven't read the details on this one but what it appears to also share with those old units is adjustability. Most electronic equipment has gone to the automatic operation design. Manufacturers assure us that they work better than the old manually adjustable ones. I'm skeptical as I've operated both in things like Loran receivers and the trend towards automatic sets in that area meant a diminishment of ability to get a fix in marginal conditions. Under "normal" conditions the newer ones are easier to use but my experience has been that i was rarely desperate for a fix under normal conditions. For instance, getting back to echo sounders, how does the modern depth soundr deal with thermal inversions? Short answer is, they don't. You just get erroneous data where your depth varies from 3 fathoms to 300 fathoms. anyone who has messed about with an old receiver versus a PLL equipped one will know what I mean. Anyone familiar with this machine?

NASA????? It's even got the exact same NASA logo from the 1970's, with a little arrow added.

I'm going to e-mail them and ask if I can buy a Gemini capsule. I've always wanted one of those.

Think ya used enough dynamite there, Butch?

It looks similar to the Seafarer d/s I had on my previous boat. I really liked it. I preferred its clock face analog display to the digital d/s on my current boat. With some experience you can tweek the settings to get an indication of the bottom type.

This U.K. instrument company is not affiliated with the U.S. NASA space agency.

They did pirate the NASA "worm" logo, though. One of the unofficial reasons NASA went back to their original "meatball" logo.

You call that a retro sounder? This is a retro sounder!
