Hi Everyone,
If you have read else where on this forum you know that we have been questioning the method of checking equipment for draw weight and arrow speed.
Wankinquoah Rod and Gun Club IBO World Qualifier will be checking equipment in accordance with IBO Rule III – A -1 & 2 "Equipment Grains per pound and Arrow Speed" For clarification of this rule we turned to IBO and the response was as follows:

The bow would be weighed on a bow scale. The peak weight in that process is the bows weight. I would suggest you weigh the arrow first then the bow. Grain scales are just a little more consistent. Say the arrow weighs 300 grains. The rule for arrow weight to bow weight says that 300 grains is legal to 60 pounds. With allowance the bow could weigh up to 62 pounds and no more.

The procedure we will use is as follows:

1 - We will choose an Arrow from your quiver you will shoot it through a chronograph if the arrow travels at less than 280 fps (variance of 3% 288.4 maximum) you may move on to the course –

2 - If the Arrow is grater than 280 fps (variance of 3% 288.4 maximum), then we will weigh the arrow then pull the bow for peak draw weight – We will divide the arrow weight by 5 and the result is the required bow weight plus allowances. Example: Arrow weight 300 grains Bow peak draw weight can NOT be more than 60 pounds, (62 pounds with the allowance).


Note: The scales will be certified by the local Weights and Measures officer the day before the shoot.
