Or to give it its full title – The SG Pulse Precision Shooting Assistant! Ah, don’t we all love a gadget – especially if it will improve our shooting simply by bolting it to our rifle? SG? – Shooters Global.

I’ve always known that canting a rifle will affect the fall of shot but I’ve never known exactly by how much. I recently read – on a reliable website – that just a couple of degrees of rifle cant could move your shot about 6 inches at 1000 yards! If you shoot F Class for example, that means your otherwise perfect shot, but from a slightly canted rifle, will land outside the 10 inch bull. A bit worrying that – especially if you shoot off a bi-pod on grass.

I’ve always had bubble levels on my long-range rifles but I must admit I more often choose the wind-flag over the bubble as I squeeze one off and anyway, how accurate is that tiny little bubble dancing between two lines?

I know the electronic ‘traffic light’ levels have been around a while but the sheer cost has always put me off – until now, when the more reasonably priced SG Pulse came on the market. Had to have one!

I couldn’t wait to get it on my rifle but first I had to…….. yes, you’ve guessed, there’s an app to be downloaded (but it’s free) and you can then set up the SG on your smart phone.  To be honest, it’s not that difficult – especially if you have help from a 12 year old! The SG Pulse is like a lot of gizmos these days – it does far more that you need it to do – it’s a level for gawd’s sake – don’t complicate it!

The SGP doesn’t have a battery – you charge it via a USB plug and once charged it should run for 50 hours. It’d be great then if you just bolted it on and headed to the firing-point but no – not that simple.

Firstly you need to mount it – to your Pic rail – or M-LOK hand guard. I opted for the Pic rail – a simple enough job except that the mount bracket is quite wide so I had to ‘shuffle’ my scope a wee bit to accommodate it. One good thing – it doesn’t need to engage with one of the Pic rail slots, so that gives you a bit more latitude. You must decide where to mount it – in front of your scope’s focus knob or behind it. It doesn’t stick out very far so I opted for ‘in front’- i.e in plain sight but it was still partially obstructed by the back scope mount nut. However, it’s so bright (you can adjust this) you can’t fail to see it whilst looking down your scope.

Before you can take it on range, you have to ‘level’ it with the iPhone app. OK, no big deal – you can do this at home. Set your rifle level – i.e. ‘no cant’ and simply ‘pair’ the SG. The smartphone screen shows a pic which moves as you level the rifle – very clever, very easy.

Out of the box, the device is calibrated to be used in the horizontal position – i.e. on your Pic rail but if you wish to mount it at another angle – say on a hand-guard – it’s possible to easily recalibrate it – via the app.

Pressing the screen switches the SG on and off. The indicator lights are really bright so you ‘notice’ it – rather than having to stare at it – as you would with a small bubble-level.

I’m really looking forward to using the SG at 1000 yards but its first outing will be at 600 yards giving me an opportunity to check my chosen mount position.

OK – I’m on the 600 yard firing-point. To switch on, simply press the screen. When the SB/rifle is level, it shows green – tilt one way and it turns red. Tilt the other way and it turns blue. Although I can’t see the whole ‘screen’ – as it’s partially obscured by the scope’s mounting nut – it’s easily visible out of the left eye whilst looking down the scope with the right eye. By observing red or blue, you soon get to know which way to cant to bring up green. Looking at the target and setting my crosshair on what I thought was level made me realise what an asset the SG is. It proved very easy to use  and I’m happy with my mounting position.  Once the shoot has finished, another press on the screen switched it off.

My first competition shoot with the SG is at 1000 yards and honestly, I can’t imagine shooting without it! I’m shocked how much I would have been canting my rifle and thus losing centre hits. This is such an awesome aid to anyone shooting long-range – particularly off a bi-pod. Because you are aware of the light without actually looking at it – as you would have to do with a bubble – there’s more time to concentrate on the wind and actually taking the shot.

Although I will use the SG as a more ‘seeable’ version of a simple bubble, it will actually do a lot more ‘drills’ – as they are called on the app. Check out the SG website for full details but for me it’s simply a level – much improved on a bubble version.

But there’s more – just as I was about to make this report live, I got handed another little gizmo by Phil Kelly of Kelltac Designs – the SG HUD.

This is an ingenious litle device that clips over the SG unit and transfers the signal to the eye-piece of your scope! It’s 3D printed from tough plastic and although I can see my SG device, it gives you much more versatility as to where you can mount your SG and I must admit it does improve things as the image of the red/green/blue lights are right there – on your eye-piece.

I wasn’t convinced it would be better – unti I tried it. It simply slips over the SG unit and clips on your scope’s eyepiece. You can swith the SG on and off without removing the HUD. What a great piece of kit. Email info@kelltacdesigns.com or have a look at the website www.kelltacdesigns.com
