SI-TEX T-760 Compact Color Radar Review: simple, compact radar that just does its job

I’ve been running the SI-TEX T-760 on a small cabin boat that I use for coastal trips and fishing, so this isn’t a lab test, it’s real use: early mornings, fog, rain, and some crowded harbors. I picked it mainly because I wanted a compact radar with a simple touchscreen that didn’t eat up all the space on my helm. My previous setup was an older monochrome radar with a rotary knob that felt like it was from the 90s, so this is a clear step up in terms of handling and visibility.

The first thing that stood out is how straightforward it is. You power it up, it boots in a reasonable time, and you get a clear color display with targets showing up without needing to dig into menus for half an hour. I’m not a professional captain, just a regular boater, and I didn’t need the manual for basic use. That’s already a win in my book, because too many marine electronics are overloaded with settings you never touch.

I’ve mainly used it in short to medium range, staying under 12 nautical miles most of the time, with the dome mounted on a small mast above the cabin. In fog and light rain, it did what I bought it for: showed me traffic and shorelines when my eyes were basically useless. It’s not magic, you still have to interpret the returns, but after a couple of outings I was reading the screen pretty confidently.

Is it perfect? No. The interface feels a bit old-school compared to the big brands, and the touchscreen isn’t as slick as what you get on a modern phone or tablet. But if you want a simple, compact radar that fits on a small to mid-size boat and you’re okay without all the fancy networking and integration, this thing is pretty solid. That’s basically how I’d sum up my first weeks with it.

When I bought the SI-TEX T-760, I was basically choosing between this and some entry-level radars from the usual big names. The T-760 usually comes in at a slightly lower or similar price than those, depending on where you shop. You’re not getting the most modern interface or deep integration with fancy multifunction displays, but you’re getting a complete radar package (display + 4kW dome) that works on its own. For a small to mid-size boat where you don’t want to redo the entire electronics suite, that matters.

In terms of what you actually get for the money, I’d say it’s good value if your priority is straightforward radar performance. The picture is clear enough, the range is fine for coastal use, and the touchscreen is functional even if it feels a bit outdated. You’re not paying for a ton of software features you might never use. For me, that’s a plus. I wanted something that helps me see traffic and land in bad visibility, not a huge integrated system that takes over the whole helm and my wallet.

Where it loses a bit on value is if you’re already deep into another brand’s ecosystem. If you have, say, a modern chartplotter from a big brand, sometimes it makes more sense to buy that brand’s radar and just plug it in, share waypoints, overlay radar on charts, and so on. The T-760 is more of a standalone solution, so you don’t get that tight integration. If you care a lot about that, the value drops for you. If you just want a dedicated radar screen and don’t mind it being its own thing, then the price/performance ratio is pretty decent.

All in all, I’d call the value solid but not mind-blowing. You get a reliable radar setup that does its job and doesn’t feel cheap, at a price that’s reasonable compared to the competition. There’s better out there if you’re ready to spend more and want all the bells and whistles, but for a practical boater who wants radar without going overboard on cost, the T-760 sits in a comfortable middle ground.

Design-wise, the T-760 display is on the practical side. The 7-inch screen is housed in a fairly thick plastic body, not ultra-slim or fancy, but it feels made for a boat, not a living room. The bezels are a bit chunky compared to modern chartplotters, and the user interface graphics look dated, more like an older GPS than a modern tablet. That said, once you’re at the helm, what matters is: can you read it easily in sunlight, and can you hit the right controls when the boat is bouncing? On both points, it does the job.

The touchscreen is resistive, not the glossy smartphone-style capacitive screen. That means it works with wet fingers and gloves, which is actually a plus on a boat, even if it doesn’t feel as smooth as a phone. You need to press a bit more firmly, but at least you’re not accidentally changing settings every time a drop of water hits it. There are also a few physical buttons for basic actions, which I liked when the sea was rough. Relying 100% on touch in bad weather is annoying, so a couple of hard keys is a good choice.

The radome itself is a standard 18-inch white dome, nothing fancy. It’s compact enough to fit on a small mast or radar arch without looking ridiculous on a 20–25 foot boat. Weight-wise, it’s manageable to lift and mount with two people. It doesn’t scream premium design, but once it’s up there, you don’t really care what it looks like, you care that it spins and sends a clean signal. Cable runs are straightforward: one main cable from the dome to the display, plus power.

So overall, the design is practical, slightly dated, but functional. If you’re into super sleek glass panels and high-resolution icons, this will feel a bit behind. If your priority is a screen you can actually see in daylight and poke with a wet glove, the design makes sense. Personally, I’d call it utilitarian: not pretty, not ugly, just built to do a job and survive on a boat.

The product listing mentions battery powered, but in real life on a boat, you’re obviously wiring this into the 12V system, not slapping AA batteries in the back. On my setup, it’s running off the house battery bank through a dedicated breaker. So the real question is: how much does it draw from your batteries, and is it an issue on a small boat with limited capacity? From my use, the T-760 sits in what I’d call a reasonable range for a 4kW dome and 7-inch display. It’s not the most power-hungry thing on board, but you do notice it if you leave it on for long runs without the engine charging.

On a typical 4–5 hour outing with the engine running most of the time, I never had battery issues. The alternator keeps up easily, and the radar is just another consumer along with the plotter, VHF, and a few other electronics. Where you have to think a bit is if you like to sit at anchor with the radar running as a watch tool, or if you have a small battery bank and a weak charging system. In those cases, the continuous draw of the radar plus display adds up, and you’ll drain your house bank faster than with GPS-only gear.

I don’t have lab-grade measurements, but based on my battery monitor, the overall consumption is in line with other radars in this class. It’s not particularly low-power, but it’s not wasteful either. If you’re already used to running a 4kW dome, this won’t shock you. If you’re coming from a simple GPS and fishfinder setup, you’ll notice the step up in power use when the radar is spinning. I ended up making a habit of switching it off when visibility was good and I didn’t really need it, just to save some power on longer trips.

So, in short: power-wise, it’s perfectly manageable on a normal small to mid-size boat with a decent battery and alternator, but don’t expect it to be ultra-efficient. If your electrical system is already on the edge, you might have to think about upgrading your batteries or being more disciplined about when you run it. It’s another reason I’d call this setup practical rather than fancy: no special low-power tricks, just standard radar consumption that you plan around.

I haven’t owned the T-760 for years, but I’ve put it through a decent mix of salt, spray, rain, and vibration. The boat lives in saltwater, and the radar gets used regularly during the season. So far, no water ingress, no fogging inside the dome, and no weird behavior from the display. The casing feels solid enough, and the buttons haven’t gotten mushy or sticky, even after being hit with wet, salty fingers and the occasional sunscreen mess. It’s not pretty, but it’s holding up as you’d expect from marine gear.

The radome has taken some solid spray and one or two accidental knocks from gear when moving stuff around. No cracks, no discoloration yet. Mounting hardware is basic stainless stuff; just keep an eye on the screws like you would with anything else on a boat. I gave it a rinse with fresh water every now and then, which definitely helps keep the salt from baking on. Mechanically, the scanner inside spins quietly, no odd noises, and startup is consistent every time. If it was going to complain about the environment early on, I’d expect to hear grinding or see random dropouts, and I haven’t had that.

The display is usually the weak point on cheaper gear, especially the touchscreen. Here, the screen has some minor micro-scratches from normal use, but nothing that affects readability. The brightness is still good, and I haven’t noticed any fading or weird color shifts. The touch response is the same as day one. The unit has been in direct sun for hours at a time during summer trips, and while it gets warm, it hasn’t shut down or glitched on me because of heat, which I was half-expecting on very hot days.

Long term, I can’t pretend I know how it will look in five years, but based on what I’ve seen so far, build quality seems decent for regular recreational use. It doesn’t feel like a toy, and it hasn’t given me any warning signs. There are definitely more premium-feeling units out there from bigger brands, but they also cost more. For a mid-range radar on a small boat, I’d say the durability so far is reassuring. Just don’t skip the usual maintenance: check connections, rinse the dome, and protect the display when the boat is not in use.

On the performance side, this is where the T-760 justified its place on my boat. With the 4kW 18-inch dome, target detection in the ranges I actually use (0.25 to about 12 NM) was pretty solid. In light to moderate fog, I could clearly pick up other boats, shorelines, bigger buoys, and harbor entrances. Once I spent a bit of time tuning gain and sea clutter, the screen wasn’t a mess of noise, and I could quickly see what was around me. It’s not fully plug-and-play; you do need to learn how the adjustments affect the picture, but that’s true of almost any radar.

Where I really felt the benefit was on early morning runs to fishing spots. Before sunrise, with no moon and some haze, I used to rely only on GPS and my eyes, which is honestly not ideal near traffic lanes. With the T-760, I had a fairly clear view of bigger targets, so I could spot crossing traffic and adjust course early. It doesn’t magically show every little kayak, but for normal coastal traffic, it gave me information that I simply didn’t have before. Compared to my old monochrome radar, the color display makes it easier to separate land, sea clutter, and targets once you understand the color scheme.

In heavy rain, like during one stormy run back to the harbor, performance drops a bit, as with most radars. You get more clutter on the screen and you have to play with the rain clutter control. I managed to get a usable picture, but it took more tweaking than I’d like. The auto modes are okay but not perfect; you’ll get better results if you’re willing to manually dial in the settings. If you want a radar that just auto-adjusts perfectly all the time, this might feel a bit basic, but for me, once I found settings that worked, I mostly stuck to them.

Overall, I’d rate the performance as reliable and good enough for serious recreational use. It’s not cutting-edge, and it’s not packed with advanced target tracking like the most expensive systems, but for navigating in low visibility, avoiding traffic, and keeping an eye on the coastline, it does what it’s supposed to do. I never felt like it was lying to me or missing major targets, which is what matters. If you’re coming from no radar or a really old unit, you’ll feel the difference the first time you head out in fog with this thing running.

The SI-TEX T-760 is basically a 7-inch color LCD touchscreen display paired with a 4kW 18-inch radome. So, you’re not getting some huge open array monster; this is clearly aimed at small to medium boats that need decent radar without turning the helm into a spaceship. In the box, you get the display, the dome, cabling, and the usual mounting bits. No surprises there, but don’t expect fancy extras – it’s pretty bare-bones, which is fine if you just want it to work.

The display is the heart of it. The 7-inch size is small enough to fit on a cramped helm but still big enough to read in choppy conditions. The interface is mostly built around touch controls, with some physical buttons for the basics. You’ve got the usual radar modes: different ranges, gain, sea clutter, rain clutter adjustments, and some basic target features. It doesn’t try to be an all-in-one chartplotter, fishfinder, and coffee machine. It’s mainly a radar, and honestly, I prefer that. Less to fiddle with, less to break.

In practice, the 4kW power with the 18-inch dome is fine for coastal and nearshore boating. I used it mostly in the 1–12 NM range. It can go further, but on a small boat, you’re more worried about what’s within a few miles anyway. Targets like other boats, buoys, and shorelines show up clearly enough once you tweak the settings a bit. It’s not as polished as the big-name radars with fancy auto modes, but once you get your preferred settings dialed in, you can more or less leave it there.

Overall, the T-760 feels like a no-nonsense radar setup. You don’t get a ton of marketing features or deep integration with other electronics, but you do get a compact, self-contained radar that gives you a clear picture around your boat. If you’re expecting a full glass-bridge experience, you’ll be disappointed. If you just want a solid radar that does radar and not twenty other things, it lines up well with that expectation.
