English Yes, you can. Most scanners offer the opportunity to familiarize yourself with their work in test mode and place your information in surebets with returns of up to 1% free of charge on their web pages. But there is no need even to talk about serious profits with such a margin.
Surebets with unlimited profitability can be viewed on the free scanner site BMBets.com. The main advantage of this resource is that it is free. But nevertheless, I would not recommend it for betting income. The scanning speed is low compared with paid scanners and is not sufficient for proper work with surebets. Surebets are visible to a larger number of players than when working with paid resources, which increases the risk of being penalized by bookmakers.
