PRO NITRO – Band Set – Field Target – Class: Light Hunter – 0,70 mm (black / red print) – SC -Straight Cut

Band geometric: SC -Straight Cut – 20mm wide x 17.5 cm length – (with competition grade pouch: 52mm x 14mm x 2mm pouch).

Pouch size: 52 x 12 x 2 (Large) pouch – is unique and specific – to the NITRO range and provides a steady seating and better grip for heavy gauge (large) pellets.

Our bands: The Precision Pro NITRO range of competition grade bands, designed to improve your accuracy. This world-class product range is manufactured using a proprietary process and special natural latex compound characteristics formulated for elastic consistency specifically for “kettie” (slingshot/catapult) applications.

Performance: SUPERIOR CONSISTENCY – with a SD < 0.7 fs (Standard Deviation of less than 0.7 foot a second). The following information was generated – standard length handset -as 85cm draw length – 1:5 ratio:

Heavy Steel pellet size	8.5mm	9mm	9,5mm	10mm
Grams		3.49	3.74	4.26
Grains		53.85	57.71	65.74
Avg Velocity Fs	261	253.2	244.7	237.0
Std Dev	0.7	0.7	0.6	0.6
F-LBS		7.7	7.7	8.2
KGr TF/S		13.6	14.1	15.6

Ratio: 1 : 5 // relaxed 1 : draw is 5 // cut your band to you draw length.

Consistence in velocity = Precision (small groups (small deviation) = Accuracy.

What is in the packet: 1x Band Set, Thick 0.7mm, wide – 20mm wide x 17.5cm long, with competition gade – field target pouch: 52mm x 14mm x 2mm pouch. ideal 85cm+ draw. (Remember

Band construction: The bands & pouch is tied with our famous special KETTY supurb – “Wrap & Tug” technique, extremely small and clean bind – tight to the pouch. KETTY DOES NOT USE – any type of (restriction-) knots associated with band damage.

Straight cut bands, caveat all – it has the best duration expectancy.

Excellent performer: Intended for (A) 9 /9.5/10 mm Steel (and- 9mm Light Hunter – 10 heavy hunter) , – and 9-10 mm Ketty Yello Tracer – Clay ammo pellets.

Precision (i.e. internal mechanical metrics – ballistics [properties and performance]) is 100% calculable/science, the foundation of accuracy (i.e. external ballistics/75% calculable/voodoo) and down-range performance. The dedicated materials used by KETTY for precision (consistent, optimised performance) have been proven superior in precision shooting and demonstrated scientifically from the start to the middle and to the end of band life.

Elastic materials: Characteristics are critical for optimised performance to tune the precision/balance ratio of tension, expansion – acceleration rate for consistent velocity. It is a science that KETTY understands!

Durability: Read – FAQ / Band Set-up: (1) Draws Length (2) Band taper – very important for best performance. These are competition grade bands, designed to provide optimum reliable super consistency from shot 5 to 300 > depending on setup, straight cut (no taper) expect in excess of 500 shots.

Band Stretch (Draw lenght): As a rule of thumb, for performance bands, 4.5 X times stretch is the bottom limit and 5 X times the upper limit. In other words if your draw is 50cm, the free (active) band length is between 10cm (shortest / 5 X) and 11.1cm (longest / 4.5 X). (4) Cant Cutter – when the roller cutter is at an (extreme) angle, it creates uneven edges, that originates tears.

Draw (pull) Length: How long is your draw and how to measure it? There is the scientific method and the field method.

Scientific Method: Take two pieces of string; affix it, each to a post in centre of the band position. Assume your active shooting stance, stake the two pieces of string in your rear hand close to the kettie frame, (I prefer – with close eyes), raise the kettie and hold it out to the shooting position and run your rear hand back tensioning the strings under your thumb (pinch) and settle in the anchor position. Hold the string pinch and measure the length of each string. Use the average length if they differ. Very experience shooters will have no or an insignificant variation, whereas beginners will have greater variation because of their inconsistent form (posture). The importance is, that for various reasons (fatigue, complacency, etc) you will inevitably default to that “hold” (shooting position) in an event.
The Field method is literally a “rough cut” option that I use. It entails the slightly over estimation of the actual cut length. Already fit it with a pouch, and affix it, then pull it to max (comfortable) length, measure (estimate) the (extra) length of pull past the anchor point. Example: 3.5 cm extended pull, thus – 3.5cm divided by 5cm = 0.7 cm to sorter the free draw. It is a simple and easy method – if you are in a crunch, but not scientifically correct (ideal).

No 1 Rule: Always wear eye protection, safety or shooting glasses.

No 2 Rules: Always stretch you bands first at hip or waist height, warm it up with 1 – 3 pulls and INSPECT the condition of the bands. at any sign of wear or damage, change it preventative.
