The sinto eon, steel. Black is the latest version of the popular sento, eon steel what’s. The difference i hear you ask well first of all it’s black, but secondly, this actually comes with the bulman algorithm, along with the adjustable gradient factors and the opportunity to turn this into a fully specked up. Technical, diving, computer, eon, steel. Black comes in this smart protective case. If we unzip and have a look inside, we’ve got the unit there and then as well as that, you also get quite a nice little protective rubber case. A charging cable as well, and it also comes with a bungee mount. So you’ve got various options of how to mount the computer on your wrist. One thing: you’ll, probably notice, is that there’s a little bit of flickering on the screen when you’re watching this on the uh on the video. In reality, the screen is nothing like that at all, you’ll see it as well, when i’m, under the water and it’s, actually just simply to do with an led screen, refresh rate and that’s picked up by the camera. So you don’t need to worry about that being what the display will look like when you’re under the water to go into the menu settings on the e on black. You simply hold down this middle button for a couple of seconds and that’s. One of the really nice things about sunto is how easy and simple it is to navigate through the menus.

If i go down to dive settings to select it all, i do is push this central button and now again, as you saw using these up and down arrows. If i go down to parameters here and select that i can show you where it’s possible to change the algorithm, so in here, if we select you can see, you have the option of running either with the bullman or with the standard syntofuse algorithm. Also within this menu, you can alter your gradient factors, it’s possible to change your low or your high gradient factor there again, it’s, just a long push to go back a step, and i can also change my last stop depth. If i want it to be six meters instead of three, which a lot of technical divers prefer and also within a deco profile, it’s possible to change it between stepped and continuous, continuous is the standard sento way of measuring deco, which gives you a constantly moving ceiling. That gradually creeps up as your deco obligation reduces. If you change it to the step setting, it will give you a far more traditional 12 meter. Nine meter six meter three meter increment deco setting and what that allows you to do is to match the computer up with somebody who’s using a different brand computer, but still running on the same bauman, algorithm and gradient factors. I had the opportunity to take this unit. Diving last weekend and actually put it through its paces while set on the bulman algorithm.

So this is me heading down for the first dive of the day, just a shallow first dive to 16 meters, which you’ll see on the screen just shortly there. So 16 meters down four minutes in uh 34 minutes of no decompression left and at the bottom you can see i’m on air with 214 bar it’s also possible to change what you see on the bottom screen by pushing the bottom right hand, button that will also Give me things like my air consumption or my remaining gas time, and i think it’s also worth showing and noting just how crisp and clear the screen is it’s, not the brightest unit. But i think in terms of its contrast and its clarity it’s one of the easiest to read. So this was the next day when we did a deeper wreck, a submarine down at around about 35 meters, and we dive this on a 30 70 bullman, which is what the uh suntoes preset to now. You can play around with the gradient factors, but fiddling around between sort of 30 to 40 or 70 to 80. You know on a 30 to 40 meter. Dive is a bit like eating a giant bag of minstrels and then arguing whether leaving two or three in the bag is healthier for you. But there you go. You can see. I’Ve got about four minutes. No decompression time left uh at this particular point into the dive and later on i’ve now racked up 12 minutes of deco, which you can now see in the orange there and i’ve got a six meter ceiling and later on again now got 19 minutes of deco And a nine meter ceiling, so you can really clearly see that lovely sort of stepped jumps.

The three meter increments, which is just very similar to a lot of other tech, diving computers on the market – very easy, simple to use here and in this final it’s, pretty much a still. So apologies for the poor uh screen quality, but you can just see i’m. Now six meters and i’ve only got four minutes there of dco to do, and i just found the computer incredibly simple, to use and very very clear and easy to see so it’s a real winner and now to make up for some of that rubbish. Imagery here are some nice bits of fish and a lovely ray that we saw swimming along, but all in all, it was just a great weekend’s diving and i really enjoyed using the eon black ii. Another nice feature of the sunto computers is that they all pair up to the suntow app i’ve, downloaded it here and you can see how you can go in and add your information and add dives. So this is a dive that i completed on the uh, the sun tone and if you go in i’ve added this rather snazzy picture, and it gives you the profiles there of the dive and also telling me what gradient factors i used. What uh, which algorithm i used the dive profile as well, and i can even go in and share that photo to social media with a nice little over graphic of my dive profile there. So there you have the sunto, eon steel.

Black suntow can probably lay claim to being the first manufacturer to truly produce a computer that bridges both the recreational and technical market without either one of those things being kind of shoehorned into an existing computer.
