This saga has been ongoing for about two years so far so please be paitent, I will get to the point eventually.
So, having lived with an elderly TP5500 for many years I was getting fed up with the mechanical noise it made when I spotted a used TP20 in a classified ad in one of the comics. The guy lived a fair way away but agreed to meet half way (maybe alarm bells should have rung at this point?) anyway, we met as agreed, I inspected said TP20 which appeared ok and a deal was struck at £120 which I thought was a fair price.
BUT...first time on my boat and it did all sort of crazy things..
course variations up to 30 degrees
constantly buzzing back and forth by 10-20mm, it is never still
locking at full extension or retraction when tacking so I tacked and gybed, and tacked and gybed and...you get the picture.
So basically it was *uggered and I had been conned. Needless to say the seller was not traceable - lesson learnt, perhaps but it gets better.
So I sent it to Simrad, who pronounced that it needed a new pcb and seals and case top as water had ingressed the unit, £135 thank you very much! Which brings my bargain upto the price of a new one - ouch.
So I paid up, plus £12 odd to the post office to ensure it arrived in one piece. About 3 months later, I kid you not, and after quite a nuimber of phone calls I finally got it bck, just in time for laying up.
Next year, tried it in anger for the first time and was no better, still constantly buzzing around and doing crazy things - an autopilot with a mind of its own is not what you want when sailing single handed. Back it went again,(another £12 quid post) 'but we can't find anything wrong with it Sir' 'but we have changed the feedback circuit just in case'. So I tried again, and went round and round in ever decreasing circles whilst it did its own thing. Just to add insult the bleeper had stopped bleeping by now. Returned it again, (+£12) and managed to extract a loan unit from Simrad whilst they pondered but the answer came back the same, 'we can't find anything wrong with it, but we will change the compass although we don't think it is faulty'. So swap the loan for my unit (+£12, I hope someone is keeping a tally of this!). Finally I got 'my' TP 20 back, but not quite as it had a completely different serial number to the one I had sent in - I was told it was 'only the case, the innards are all yours, and new as well, the unit is perfect Sir!'
Is it ****, it still hunts back and forth driving my crazy with the constant noise, it still has a mind of its own and tacks/gybes/tacks etc etc and now and then loses the plot entirely and wanders off course by 30 degrees or more. The bleeper has died again so this weekend I thought I would open it up and have a look - amazing, rubber seal chewed up in places, several screw locations broken, the bleeper hanging by one lead, the other in mid air, the compass housing cracked and broken with bits rattling around inside the housing - basically it is knackered, and most definatly not my original TP20 innards.
Ok, so I have rambled on, and feel better for venting steam but in all seriousness what I need to know is:
Is the Simrad TP20/22 and good? Or do they buzz back and forth all the time (even in a marina!) lock in position, go walkabout when the mood takes them, or have I just been lucky?
Answers on a postcard to Simrad Ltd...!!!! /forums/images/graemlins/mad.gif
 
I cannot understand how you can put a laughing smiley at the end of that story ? You must have one hell of a character trait to still be laughing !

I would have been to Trading Standards before now with complaint about service costs and no cure.

As to TP20 - it's a good machine, IMHO as good as the others.

You have been extremely unlucky and basically conned by more than the seller by appearances.
 
Ok, I've killed the laughing man...
No, I am seriously *issed off about it but the trouble is the timescales involved make it unfeasable for me to persue through TS or any other means. Maybe someone from Simrad will read this and do the decent thing...lol
Ah well maybe not, I can but dream.
 
My well used TP20 is one bit of kit I would not do without, six years old now, it has worked faultlessy, sorry to hear of your woes.
 
My Simrad TP22(which is new) also hunts in and out constantly, making a hideous noise. It will not steer my Jaguar 27 while under sail, any wind strength from any direction, closer than about 30 degress either side. It works OK while under power, while still hunting in and out. It is never still or quiet. I have tried all the available adjustments. A complete load of rubbish in my not very humble opinion.
 
That's interesting, if I had not been in rant mode and had explained myself better, what you have described is exactly what I have been experiencing.
 
Two suggestions to make:

1. Check your power supply. Poor connections leading to voltage drops when the drive cuts in might affect it

2. Next time buy a Raymarine one. Although recent suggestions are that they are not as good as they used to be. Reports on service have usually been good.

(still using a Nautech Autohelm bought around 1979 or 80. Would like a more modern one but it wont go wrong!)
 
Thanks for your thoughts Vic. I'll certainly check the supply, it is in fairly heafty cable but I could have a bad connection.
I did consider the Raymarine but my boat's length/weight is too much for the ST1000 and the ST2000 is quite a lot more than the corresponding Simrad machine - I guess you get what you pay for.
 
...will not steer...under sail...closer than about 30 degrees...It works OK while under power...

Ours too.

...Next time buy a Raymarine one...

Just what we did and it works much better; well worth the extra £30 or so!

...my boat's length/weight is too much for the ST1000...

I also noticed that the Simrad claims to have more grunt/capability than the Raymarine equivalents provide; whilst we are inside the ST1000 recommendations anyway, I've always been dubious about this. I'm reminded of the marketing claims for 1970's Japanese motorcycles; whilst they invariably had substantially more horsepower than their British/German/Italian equivalents, reality often showed that these horses were much smaller. /forums/images/graemlins/wink.gif
 
I also have a TP22 and it also hunts in and out constantly
It also locks itself out and sometimes even blows the fuse!
It does however usually keep on track when it does work
The one i have has the anoying habit of just going to standby for no obvious reason.
If i unplug it, it resets itself and works, and sometimes it just wont work again untill i leave it for some time.
It only does it every so often but i would never totally trust it again
I asked simrad about this fault and they said they had never come across the problem and i should send it to them if i wanted.
Imo not worth the trouble.
I used to have a raymaine 1000 and it never gave a single fault
I woulden't get a simrad one again

Nothing untoward on my boat save for the usual clutter around the stern but nothing has changed since I had the TP5500 which worked fine. Something I forgot to mention is that I have been unable to calibrate the compass on the TP20

Well it made the bleeper bleep but other than that 'normal' service was resumed!
 
With the money I got from successfully sueing the supplier of my Simrad tillerpilot (cos Simrad refused resposibility for their Cr*p) I bought a Raymarine one. So far so good (after a couple of free repairs).
 
I have a TP10 It does more or less continually move back and forward that's how it keeps the boat on course. I did have trouble when first fitted whereby it would go into standby mode once the arm reached the full length of travel during a tack this was down to a bad connection giving a high resistance joint.
I had to replpace the drive belt when it was just over 2 years old.
It gave me trouble 2 weeks ago by not performing at all on it's own and would only move in short burst when I tried to move it manually. I opened up when I got home and discovered it was damp inside. I spray of the PCB with dewatering spray and a week in the airing cupboard seems to have fixed it as I used it for several hours this weekend.
Would I buy another? Probably not.
 
I have a TP10, bought new earlier this year. Out of the box, it did hunt back and forth quite a bit, so I (eventually!) read the manual, and adjusted the ‘seastate deadband’. This basically seems to make the TP less sensitive, so it doesn’t try to respond to every tiny course adjustment. It’s been fine since then.

You can download the manual here: http://www.simrad-yachting.com/en/Produc...ots/Downloads/.
 
Had a TP20 in my Fulmar for 2-3 years and it worked very well. Much simpler controls than the equivalent Raymarine but lacking the compass readout which I never used. I had constant problems with Autohelms in earlier years - not resistant to West Highland rain and drive problems. !990 2000 however very good for 13 years, then obsolete for first repair.
