Sonar for sub locating

[scott t]

I ran across this web page while looking for a sonar symbol.

Something like this might be useful for locating a boat. I haven't
read the whole thing but it looks interesting.

Here are a few line from the page:
"Ivar had a nifty sonar gadget for finding the boat. It comprised two devices housed in clear plastic cases, each turned on by a magnetic reed switch. One unit was a sonar transmitter hung from the boat. The other device was a receiver carried by the diver to locate and home in on the transmitter signal. It had a couple of LEDs for direction finding."

"Hence my current project: a sonar buddy locator. The concept is a cheap, unobtrusive, neutrally buoyant sonar transceiver rated to a depth of at least 40 m for each diver. It would allow either diver to locate the other should they loose visual contact. The device might also be useful on night dives."

Seems like it might work,

Seems like it might work, but if it ever goes commercial it will be aimed at the diving community and anything involving scuba equipment is expensive, so it might a pricy item for an RC sub.
