Yes, still works just fine, thanks.

If a radar can spot a 40cm non-reflective rubber pot buoy amongst 2m waves then the software mist be miraculous, and the military will be desperate to get their hands on it.if only I'd have thought of that

The military do have their hands on such technology though, have done for many years. He said F3 too, I've never seen 2m waves in a F3. Some swell perhaps, but not 2m waves.

Keep up, I said sea state three. ?
And you are still wrong. I've used small craft radar on various yachts and motorboats. Anything more than fairly calm, you got no chance of seeing pot markers.
I've also used high definition military navigation radar, much more powerful. But you ain't gonna see pot markers very often with that, either.
Back to small craft, many places in the world outside your flat calm lake Solent use things like empty plastic water bottles to mark pots......
You may get a sniff of an ODAS buoy mid ocean but don't hold your breath on that either.
Time to stop your dreaming, I think.

We picked up a badly marked pot whilst under sail along the Algarve coast yesterday. It wrapped around our Duogen. Fortunately the pot line ripped clear of the pot or we may have destroyed the Duogen. As it was we only bent the water drive unit arm. The potential for hundreds if not thousands of pounds worth if damage does exist.

I would say that whole coast is not the place to sail with stuff dangling over the stern. Depending on the season, there's often gazillions of pot markers almost all the way to Cape Trafalgar. Plus the fish farms off Faro. Now that's something lusting might find on his small craft radar with their big special marks and radar reflectors!
The tuna nets, again, in season are well buoyed too.
Am I right in saying you've sailed that area before? Were you fishing for orcas? (Joke). ?
A lot have dan buoys with different colour flags to denote the owner, I believe. Does make keeping a good lookout essential, but even then, not all are clear and can get dragged almost under on the tide. Again, general information for others here geem, not a chap of your calibre!

I have used the equipment on my boat in various conditions and with respect you're not qualified to tell me what my equipment can or can not do on my boat. Your experience is completely irrelevant to the question of whether I am right about my system so suggest you stop commenting on other people's experience and concentrate on your own.
The fact remains that my set picks out more buoys in more conditions more often than eyeballs.

Having used lots of small craft radars, I quite simply don't believe you. That's it, really......?

Fair enough, I don't actually care if you believe me. The facts remain unchanged regardless and I will happily continue using my radar to improve my safety and telling people how well it works so that they can also benefit from the added safety.

Except it doesn't...
However, I'm all for people fitting and most importantly practising with radar. And even more importantly understanding how it's abilities degrade with increasing sea state, rain, etc. Which happens....

Except it does, I know because I've seen it. Those of us with the kit know that it does and happily practice and use it for safety alongside other less reliable solutions.

This was a dark blue can, no flag. Just about level with the surface. The flag variety are easy enough to spot. We just got caught out by the plonker that couldn't be bothered to mark his pot adequately. He won't be hauling that pot again.

Ah, you're using it alongside. That explains it. ??

Keeping up the theme of 'My pot's deeper than your pot', passed a couple in April in the Setubal Canyon S. of Lisbon in >500m. Well, tethered buoys on the surface, anyway.

I was under the impression that French fishermen had to have lights on their pot markers once beyond a certain distance from the shore. I have certainly seen a few marked thus in the Dover Straits.
I was also under the impression that UK fishermen were subject to rules once the position of the pot was over a specizfied distance from the shore. That being said I am not sure that in either case the fishermen themselves have actually received the memo???

Between Plymouth and Peterhead, where I turned round, the deepest I had on the echo sounder was 110 meters.

But as you know the Channel and the North Sea are noveau “seas” and mere slightly covered old land masses. Need to go North and West for proper seas.

Interesting. I suppose it depends how far back in time you mean. I was thinking it would make a good subject for a book for yachtsmen and other mariners, and even a bit of general interest. What is underneath us when we sail, or even hop on a ferry? Geology, mountain ranges, wrecks, life-forms, explosive dumps and 101 other things. Sailing the N.Sea I find it totally mind-bending that for millions of years, huge wild beasts used to roam below my keel as if it was the Serengeti. Plus some of our ancestors of course..

Ah! But there's always the chance you could bring up a mammoth's testicles when hauling the anchor in the North Sea.

I never motored the north coast of cornwall at night - it isnt the place for a small boat to get tied to the seabed by some half sunken pot buoy. And many of them are half sunk, carrying no stick or flag and swept under the surface by the tide. Your fits paragraph is quite wrong in that respect.
In the nature of things you dont get tangled very often - twice in 30 years for me. But when you do it can be a serious safety issue. Its time that fishemen were foreced by law to have sticks flags and a light on each buoy.
