“Sensing the sea bottom” - possible?

[Timothy L]

I’m looking at different steering solutions for the Virginia in 1/72. I have ordered and will play around with Bob’s version 2 swivel pump jet - but still not sure I want to go that route.

Another idea that interests me a lot is a detachable bow rudder. I really like that idea except for the fact that it’s an invitation to be broken off if you accidentally hit bottom.

A few weeks back, on the Dive Tribe, there was some discussion about “sonar like” telemetry. At least I think that’s what they were talking about LOL. The discussion was so far above my head that I was clueless.

So, is it possible to have a device that will send an alert back to the operator whenever the sub is within a certain distance from the bottom? I didn’t even try to search out this question because I’m so ignorant about the topic I don’t even know what the search words would be! Thanks.

Swivel Pump Jet Version 2. Oh really? Hehehe.

Yes. Seve search-words:

"Ideas best explored by the Graduate Class".

Test-tube washers should first learn basic principles, and practice them till competent -- only then branch out into weird ****.

So many of you bums get hung up on the bright shiny object, and skip over the basics you need to learn first:

Forward. Backward. Left. Right. Pitch up. Pitch Down. Plane up. Plane down. Surface trim. Submerged trim. Submerge. Surface.

You know... basic ****.

AND THAT'S WHY MOST OF YOU DON'T PUT MANY R/C MODEL SUBMARINES INTO THE WATER!

Crawl... stumble... walk... jog... run... sprint. Most of you are hardly past, 'stumble'.

It's called common sense.
If you can't see the bottom then you shouldn't run deep.

My left eye does not see. For that reason I have absolutely no depth perception. I have no desire to operate a sub at a depth of more than 4’ - 5’.

But - in crystal clear water, at even just 2’, I have no ability to recognize how close I am to the bottom - I try to compensate by looking at shadows etc.

Fair enough. Valid reason there to sweat bottoming the boat. It's good practice -- before you ever put a boat into water that is new to you -- is to ascertain bottom depth, type bottom, slop from shore, and water clarity. When in doubt -- keep it at periscope depth. And never operate in water you're not prepared to jump into.
