GFB Whistling Trumpet (suits all valves)The 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch.? Like the 5701 however, it is necessary to run the valve so that all (or most) of the air vents through the trumpet ? Respons valves will typically not generate the velocity required to whistle when set to 50 50 venting.

Classic and functional
Color: Stainless Mesh/ Blue Dial
High quality and affordable watch. Love the mesh band. It’s a classic, functional everyday look. Easy to adjust, and never runs out of power. Perfect for men who have smaller wrists. Bought for my husbands birthday, and he loves it.
