Welcome to WWn!
Firstly, the thread would probably be better suited to the 'Water Warfare General Discussions' forum with it's tactics and strategies section, but as you mentioned an event there shouldn't be any issues with where it has been posted (especially if you post details about how the event went, afterwards

)
As for the pic, it shouldn't be a problem, as long as it doesn't explicitly show where you live.
You probably already know that the renegade is an air pressure water blaster. Unlike a lot of air pressure blasters (especially cheaper ones) you don't pump air into it to pressurise it, you pump water into a separate chamber and compress the air already in this separate chamber. These blasters tend to perform better and, with a limit of £15, you'll probably see others at the event with standard pressurised reservoir (pump the air in) blasters or piston blasters with lower performance. You may not know that to get THE BEST from your separate pressure chamber renegade, you should pump the blaster a few times BEFORE filling it with water. This increases the pressure in the chamber for even more power, range and output!

this WILL give you an edge over others, even if they have an identical blaster (as long as they don't know about it). This is called pre-charging (you'll find details on the page linked below). The only problem is if you fire all of the water in the pressure chamber, the pressurised air (which was floating on top of the water in the pressure chamber) will exit through the nozzle, creating a 'mist shot', leaving you defenceless, and resulting in reduced performance (the pressure in the chamber won't be as high) when you pump the blaster again. Using short tap-shots, and pumping the blaster between shots (as mr. dude mentioned) will reduce the likelihood of firing 'mist shots' as it will keep the blaster's pressure chamber topped up and ready to fire. If you do fire a mist shot, you can just turn your blaster upside down and pump to put more air into the pressure chamber (the water intake is at the bottom or the water reservoir, so by turning the blaster upside down the water intake will be on the top of the blaster and will pump air instead of water into the pressure chamber). N00bs may laugh at you for pumping the blaster upside down, but you
will have the last laugh!
Full details on how to get the most out of a separate air pressure chamber blaster (or any other blaster) can be found
here. There's quite a bit of text there so don't be afraid to ask if there is anything you don't quite understand.
As for general usage tips, they can be found
here.
Obviously your blaster has a nozzle selector. The choice of nozzle is very important and depends entirely on your situation. Factors affecting which nozzle to use include:
- Range required
- How wet you want the opponent to get
- How much water is available
The last point has multiple points within it and is affected by how you play. If you have a water source nearby to use as a blaster filling station during the game, then you don't need to conserve water as much as if you can only fill up before the game, and that's it until the end of the game. It also depends on whether or not you'll be allowing people to fire at those who are filling up their blasters (obviously you don't want to be caught out with an empty blaster).
As a general rule of thumb, your mid-size nozzle should be the one which gets the most use (as it happens that nozzle also has the best range on the renegade

). Tap shots are less wasteful than emptying the pressure chamber in one go. It also means, if you miss, you can fire again rather than having to pump the blaster again.
The larger nozzle can be used to soak the opponent more heavily at the expense of range, and the smaller nozzle can be used for water conservation also at the expense of range.
Details about your particular blaster can be found
here.

The
wiki article on air pressure water guns may be focused on homemades but the technology is still valid.
You might want to take a look at the tactics and games sections on the
wiki homepage and
isoaker.com.
Finally at the end of the battle fully de-pressurise and empty the blaster.
