Mini CW Trainer Morse Code Trainer Hand Key Trainer Oscillator Button w Battery

Mini CW Trainer Hand Key Trainer Oscillator Button Battery Version

Battery-powered manual key trainer:
In response to requests from many CW enthusiasts and several old customers, we have recently launched two ultra-portable manual key trainers, which are our battery-powered trainers.

Features:
1. The size is comparable to that of an ordinary eraser, but the thickness is thinner than that of an eraser. The extremely small size makes it extremely portable, and it can be put down in a pencil case, school bag, briefcase, key box, or even a pocket. Considering that most people often carry keys when they go out, their size is almost negligible compared to keys. And it does not take up too much space when in use. As long as there is a place where the key can be placed, it has a place, which also makes enthusiasts more free to choose the place of use.
2. Only one CR2032 battery is needed for power supply, no external power supply is required, and it is free from the constraints of the power cord, which further reduces the dependence on desktop space and broadens the use scenarios. CR2032 is a very common battery model, which can be easily bought in any supermarket or even a convenience store. One battery can be used for several months, which is energy-saving and environmentally friendly.
3. When operating, not only will the buzzer sound, but the green LED light will also light up with the rhythm, and the sound and light will follow the rhythm, making it easy to control the rhythm. For beginners, whether they practice with recordings or practice by themselves, the dual cues of hearing and vision help to deepen their understanding of rhythm, correct mistakes in technique in time, and prevent QSD (bad hands). For veterans, daily practice not only does not rely on larger radios or traditional practice devices, but also allows them to visualize their own rhythm. CW is a language art and a music art. Everyone's rhythm has a unique personal style. After being visualized by the eye-catching green LED light, everyone's rhythm style is more pleasing to the eye.
4. It supports vertical hand keys for vertical operation and sweep keys and mechanical semi-automatic keys for horizontal left and right operation. Other forms of manual electric keys are also made in one "device", without compromising with any manual electric keys. No matter what the operation method is, it can be easily mastered with the help of this practice device.
