Interested in input from any with experience with Sitex autopilots by Comnav. I'm considering a Sitex SP-38 which according to the vendor is made by Comnav. It appears other than the trim color to be the Comnav P4.

Stated advantages of Sitex over Comnav by the vendor are easier support for US customers because Sitex is a US corp while Comnav is a Canadian corp. Shipping components needing work across the border is not easy.

I am familiar with Comnav hardware. And have had outstanding tech support over the phone from Comnav. Never have had to ship anything across the border for repair.
 
I miss my Comnav. Simple and reliable. My Simrad has way too many adjustments possible so the config clutter masks the needed adjustments. I wanted an integrated dashvoard which is fine, and my Simrad AP works fine, but I had more confidence in the Comnav.

What problem are you trying to solve? Comnav has been bulletproof for over 30 years.

What am I trying to solve?

  1. Replace an aging AP. A new to me boat last Nov has an antique Robertson AP100. In many ways a good autopilot but it's near or at end of life.
  2. Retain a heavy duty pump. The boat has an ACCU-STEER HPU-100 which uses solenoid valves. I want to keep that heavy duty pump setup so need an AP that will 'talk' to it. At the Seattle boat show, which is lame compared to what it used to be, the two vendors who said their APs would work with my pump were Sitex / Comnav and Garmin.
  3. An AP I have confidence in. Having experience with Comnav that's a plus.
  4. Full follow up control The SP-38 has an optional full follow up control which I highly value.
  5. NMEA 0183. I don't have NMEA 2000 on the boat, don't need it and wire runs on this boat are near impossible. Why I prefer NMEA 0183 and stand alone components is another story for another time.

I find it interesting you don't like Simrad. I have no experience with their current products. I have years of running Simrad AP-50 on work boats which was very simply the best AP I have ever used. The user interface was simple, intuitive and well, the best ever. My last boat had a Simrad AP-26 a baby brother to the AP-50. Steered and functioned as well but the user interface was not quite as good.


Comnav 1001 is hard to beat. A standard on the workboats for decades. I've got a lot of time with those as well.

I don't dislike my Simrad, but the comnav was rock solid. The old Simrad you ran was probably a Robertson. Robertson is long gone in the Simrad lineup. They are extremely adjustable which is a good/bad thing.

I can't speak for you, but if I were in your shoes and fully integrated dash wasn't a priority, I'd go Comnav. Not the Sitex version but the real thing.

BTW - I think most A/Ps run 0183 if desired. TwistedTree makes a strong argument for 0183 for autopilot interface.

Peter
 
Can't argue with the old Simrads really being Robertsons. In fact early on they were marketed and labeled as Simrad Robertson. The new Simrads? Part of the Navico group. I'm sure they are not the same thing.

Can't argue with the old Comnavs being rock solid. In my opinion not the equal of Simrad Roberston techcically or in performance. But rock solid. A major reason the work boat fleet favored Comnav. But that was the 1001. I don't know about their newer stuff.

So I come to Sitex / Comnav. If, and admittedly that's a big if, they are identical to Comnav under the hood. And if, another big if, the new Comnav is the equal of the old in reliability it would be hard to go wrong.

Next is the question of support. Sitex is a US corp, I'm in the US. Cross border can be a challenge. Previous boat had a Hurricane hydronic heater. Another Canadian product. Excellent quality. Had to get parts and service out of the US side.

Thank you for your input. I respect your contributions on TF. This old dinosaur is comfortable with the older gear and the older technology and is looking for input from users of current Sitex / Comnav. Is it good? Can I trust it? Funding and installing an AP is not a trivial exercise.

I will add one last comment re: US company and support vs cross border. Although Navionics is UK based, I believe the US is their biggest market by far with substantial support resources in the US. Their tech support sucks, at least that has been my experience. Long wait times and poorly informed techs once you get through.

BC seems to be a hive of small niche marine companies. The ones I've dealt with have been fantastic.

I recently purchased a Sitex satellite compass. Not plug and play as expected so I haven't gotten around to fully configuring it. It's on my list for this week and suspect I'll be reaching out to them for guidance. I'll let you know how it goes. Hopefully they're the type that answers the phone va hiding behind email queues.

Peter
 
I've used Sitex products for years and found their phone support is excellent. Not the most intuitive brands on the market but they always answer the phone and take as much time with you as needed.
 
You'll more than likely get right through to Chuck in service, who is very knowledgeable in most all things SiTex or ComNav. Chuck and I worked together years ago and I was happy to find him working for SiTex.
Regarding Simrad , for personal use I purposely shop anything BUT Simrad/Navico/Lowrance/B&G. Not because the equipment is much worse than any other electronics but because their service is horrible with a capital H. The fishing ships I maintain are all outfitted with Simrad autopilots and a few have simrad I3005 displays for rudder position. When I have an issue, I need to be able to get through to a tech to get the boat up and running asap. Every other manufacturer is reachable via a phone call except for Simrad. The last time I reached out to them in need of service advice, my calls ,messages and mails were flat out ignored. I was finally was given the sales reps phone number and he was able to help me (he agreed with me that their service was bad but said they were trying to hire people to fill the service void).
I try to keep the fishing fleets' electronics all the same so spare parts are universal but I'm really trying to figure our a way to start using Comnav/Sitex autopilots moving forward.
 
I have zero issue with comnav cross border support. Last year I upgraded my 1001 to the latest software and added one of the wired remotes. I spoke several times with the electrical engineer over the phone and exchanged emails as I upgraded my remote with their parts and advice. Parts came quickly, with very quick processing through customs. No issues at all.
 
PB, I installed my present Comnav pilot in 2005 and had the same concerns about them being in BC regarding parts and support. To this day, I've never needed to contact them, the unit being trouble free. Probably explains why Comnav is in so many commercial and fish boats. I've never heard of the Sitex connection, so can't help you there. Mine has always been integrated with Furuno.

Thanks to all for the very helpful replies. A great example of why this forum is so good. The depth of experience and willingness to share. I'm still on the fence re bying Comnav direct or rebranded as Sitex. If all Sitex has done is change the color of the covers and the decal then all should be good.

I've read Twisted take on 0183 for AP connection and agree with him. Further when all devices are connected via 0183 proprietary issues are largely eliminated. Current boat is Furuno, Garmin, Robertson, Icom and PC. All good. Previous boat was Furuno, Simrad, Garmin, Icom, Vesper and PC. All good. All the boats I ran in my career were a mix of manufacturers. The 0183 interface once understood is quite simple. I've lost one tool that made it easier. A standard serial port on the PC, view the 0183 stream on a terminal for trouble shooting. USB has added a layer that can make it more confusing.

To those curious about why I use 0183 and a mix of manufacturers, the short version. I have used 0183 for decades and am comfortable with it. I dislike MFDs, not just a little bit, a lot. Too much in one place on one screen. Too many menus and soft keys to accomplish simple tasks. On the last boat in my career I convinced the boss MFDs were the way to go. Got him to go for dual Furuno for redundancy. My crew and I never learned to like it and eventually ran one MFD as sounder, the other as Radar. Chart plotting on a laptop.

That's been my experience as well. Top notch engineering and production. Plug and play. Well, with my willingness to stay with 0183 plug and play is a dream not come true.

Jim, boomerang, bmarler and Ken E. Your experiences with Sitex and Comnav are very encouraging.

boomerang, unfortunate that your dealings with Simrad are so difficult. In my years of running Simrad APs and sat compasses I had almost no technical issues. Almost. When problems happened they were solved by skilled knowledgeable techs. Something that seems to be gone these days. You sound like you're one of those but your cohort is getting very thin.

FWIW, Our Si-Tex SP 70 has preformed without a hitch since the installation 6 yrs ago thanks to forum member boomerang. I had no knowledge of autopilots and mentioned to Shawn (aka boomerang )that I found a never installed Si-Tex SP-70 on EBay. After the purchase Shawn advised that I send the unit to Si-Tex to check the all functions. Si-Tex verified the unit worked property via a PHONE call and asked if I need any additional info for installation. Try that route with Simrad and see what happens.
 
The old Robertson went over to Simrad, Simrad was part of the Kongsberg group which was fine.
Later, Simrad was sold to Navico and this investment club only wants one thing and that is to see money.
Such a shame because they made a top product, and the current AP in the higher segment is still good, but for how long?
But the shareholders don't care, they want to see a lot of money as soon as possible and if the ship sinks, the profit is in.
And that's how it often goes with a company that started with passion and makes a top product and provides good service, the motivation was not the money but the product.
For investors, it's the other way around.

I do think that the P4 series from Comnav looks suspiciously like Simrad, or vice versa, even the FU has the same size.

Simrad Fisheries is still part of Kongsberg and their service, as well as equipment, is outstanding. They're not affiliated with Simrad Yachting products.

In my experience, the Simrad suite I have is fine and certainly competitive with the alternatives that are in the market. My only complaint - and it's a biggie - is post sales tech support. This seems to wax and want with many companies. It wasn't long ago that Apple Computer was hit hard for extreme wait times and lousy tech support which led to the Genius Bar model and turned around their reputation.

I'm not defending Simrad/Navico, just explaining my experience and where the issue lies. Product is fine.

Interesting observation. Which Simrad do you think is the same as the Sitex/Comnav? In a quick look at Simrad's website I didn't see a match up.
I do think that the P4 series from Comnav looks suspiciously like Simrad, or vice versa, even the FU has the same size.

Mvg,

The FU controls are very similar, also the dimensions are the same, it won't surprise me that they come from the same factory, in this case made in Mexico.

Indeed I just looked at the site, Simrad-Konsberg.
Only the specific equipment for the fishing vessels is still offered, plotters and autopilot are housed at Simrad Yachting apparently.
Thanks for the info.

Pascall,

Your observation got me to digging deeper. It's very likely the FFU and the other controller, name varies with who markets it, are the same. However when I dig into the AP computer, the heart and soul of the AP, there are differences. Starting with appearance. All three support solenoid control which I require. I will need to ensure the AP of my choice can handle the current. All three accpet NMEA 0183 input which is important to me. All three use NMEA 2000 to interconnect parts.

This will require some deeper digging through the documentation. With all the comments about Simrad's after sale support if the Comnav/Sitex system meets my requirements that is who I will go with. Both offer high quality after sale support.
 
I think you're making a good decision, and should I ever purchase a new AP I'll definitely consider Comnav.
There are many companies that take the same housing but insert their own product internally
Good luck with the conversion.

Greeting

Pascal
 
Portage Bay,
I bought a 32 GB, it had an old ComNav AP that did not have the capacity to accept a NAV input. I contacted ComNav via e-mail, got immediate response as to what unit would best suit my needs and work with the existing compass and drive unit (P2,) helped me find a qualified local installer, etc. After a year they helped me obtain a second station for the upper helm. I bought some parts direct from them and the cross border shipping was painless. I love my ComNav AP! Good luck.
Regards,
Scott

I second that. I run a Sitex workstation/sonar radar and am very happy with their support. A real person answers the phone and yes, they take as much time as needed. Great support.
 
Autopilot option

I purchased and installed an Onwa K866 on my 42' trawler. It is old school, has minimal support, but is cheap (Chinese). I've been using it for a couple of months, after a self - schooled learning curve, and it's working well. If I were doing it again, I would probably pay the much higher price for the Comnav. If Onwa would get their customer service working, I would highly recommend it.

I recently purchased a Si-Tex V200 Sat Compass. I had a question and emailed tech support. Response within 2 hours from a named individual vs generic email. I had a follow-up. Less than an hour.

Still waiting for Simrad to respond to a query from a few days ago. I really should call, but dread the 60-90 minute hold time that promises my business is important to them.

This seems to the the common theme with everyone's recent Simrad experience. It's a shame. Simrad in the past has built some of the finest gear I've ever used.

Interesting, I'd not heard of Onwa before. Seems they have quite a good reputation in the Asian work boat fleet. One poster on Cruiser's Forum says they build Furuno's autopilots. I'm not buying that and can find no evidence of it. Seems to get the good prices on Onwa one must purchase through AliExpress.

I won't be making the AP purchase soon, other $$$ priorities have popped up, boat and "real life". I'll use the time to further consider the Sitex/Comnav issue and look into alternatives like Onwa. Thank you for bringing Onwa to my attention.

Onwa has always seemed to me to be a carbon-copy knockoff of the major electronics manufactures discontinued products. Their gps models ,KP128 & KP32 units are blatant copies of a Garmin 128 gps and Furuno GP32 units, respectively. Their radar antennas are identical to Garmins discontinued GMR18HD dome antenna and Furuno's 1832 dome & 1932/42 open array antennas . A brief look at the operating manual pdf shows the same operation software as the discontinued big brand predecessors.
I'd have no problem using their product as long as they acquired the manufacturing rights legitimately and their equipment quality was as good as their predecessors. As a matter of fact, I'd welcome the opportunity to buy a legacy knock-off product in some instances , because I prefer the way they operated.

Good points. I went to their website about page. If they are truly partnering with these companies and organizations they must be on the up and up. And like you I often prefer the older to the newer. Usually a simpler interface, no bells n whistles to get in the way.
