Ban on Sonar

How long before the twats in power get round to banning echo sounders and fish finders?

It's the very powerful sonar that causes problems, long distance. Very low power depth finders have little problems, as do Low power look ahead sonar. Military stuff is very high power. I have little knowledge here, so if anyone knows the answer, I'd like to hear.

I wonder when they'll get round to banning depth charges, seismic exploration explosives, cavitating propellers, torpedoes, dynamite fishermen (a suspiciously high number of one armed fishermen around the Ionian)

Or maritime warfare, come to that. How did marine life cope with the battle of the Atlantic?

Underwater volcanos, thermal vents, seismic shifts - I guess those aren't so easy to control. The crashing of waves against shore lines . . .

Our pings are beginning to sound like fa****g against thunder, or am I just feeling cynical today?

I think you've already supplied the answer! It relates only to v.modern, high-powered sonar as used by the US Navy but not many others, which has a range of hundreds of miles and is the suspected cause of a number of mass beachings of cetaceans, all showing signs of catastrophic damage to their hearing systems. It is so destructive, the US Navy only switch it on for major exercises, and it bears no comparison to any system used previously, so WWII comparisons are not really relevant, and there's no threat to sonar/echosounder use by leisure or commercial shipping.

Comparing leisure sonar with military sonar is a bit like comparing sticking ipod headphones in your ears, with sticking stadium concert speakers in your ears.

I have decided to no longer use my echo sounder in order to avoid harming whales, dolphins, seals, cockles, mussels the US Navy and other marine inhabitants. The fact it no longer functioned correctly is neither here nor there.

I'm concerned the very prescence of my boat in the water may frighten little fish. They may think my boat is a monster that will gobble them up.

Imagine the Solent last week, there must have been millions of fish, terrified out of their lives.

We must limit the number of boats on the water at any one time - say one boat per square mile!
