How to make an underwater camera for fishing: design and accessories

The technology of catching fish in the winter has recently undergone a number of changes. In addition to improved equipment, new ways to detect the presence of fish have become popular - underwater cameras. Factory models are compact, easy to use, but have one drawback - high cost. Therefore, attempts are being made to make such a device with their own hands.

Design

For design and self-manufacturing, it is recommended to study a suitable factory design. It is not necessary to copy all the elements exactly - the underwater camera can be adapted to your own requirements. It is important to decide on the maximum drop length, image quality and sharpness control. This will depend on the cost of construction.

The camera should consist of the following components:

• Camcorder. Optimally - use a special one, designed for diving to great depths. A budget option is to buy a car rear view and make a sealed case.
• Monitor. You can also buy a car, since there is a large selection in size and quality.
• Cord for connecting the camera to the monitor. Its minimum length is 3 m.
• Ice fishing rod, reel and line. With the help of these devices, it will be easy to control the position of the camera in the water, change the depth, and quickly get it out of the reservoir.

This is the best configuration option, which can be supplemented with various gadgets. These include LED backlighting, simultaneous use of an echo sounder . In the latter case, the probability of catching large prey increases.

Consumables and accessories

You can buy components at the nearest radio market, in specialized car dealerships or on a well-known Chinese online trading platform. In the latter case, you need to take into account the delivery time and the impossibility of checking the quality before payment.

Recommendations for the choice of components:

• Monitor. You can take a car with a screen size of 3.5 ". The advantage is given to models with a fastening element - a platform.
• Camera. You can also use the car, rear view. By default, it has a waterproof case, which can be improved by making an additional box. But this is done only as a last resort, as the image quality is reduced.
• Cord for connecting the camera to the monitor. Its minimum length is 3 m. This is an ordinary three-core cable.
• Battery. Small in size, the characteristics are selected according to the parameters of the monitor.

The average cost of components is from 3000 rubles and more. You can take used models, but with a preliminary check of performance.

Assembly process

Be sure to check the possibility of sharing all the components of the camera - the connection method, the presence of connectors. In the first case, a model with classic "bananas" is chosen - three cores of different colors. Complex connection types are not recommended, as there will be problems with the tightness of the connections.

Assembly order:

1. Connect the camcorder to the monitor. This can be done using soldering or mechanical clamps. Connection points must be insulated to prevent moisture from entering.
2. Battery connection. It is important that the voltage of the PSU matches that of the monitor.
3. Installation of the structure on a mobile stand. The latter must be weighted to prevent its displacement during a strong current of a river or reservoir.
4. System health check.

The assembly process with all components and consumables will take no more than 1 hour. You can first lower the camera into a filled bathtub or other large container. The quality of the image is checked, the absence of interference. They can occur with poor-quality contacts.

Before making the camera yourself, it is recommended that you familiarize yourself with the video material, which gives practical advice:
