English Yes, you can. Most scanners have a trial feature and publish free information about surebets with yield under 1% on their websites. But it is hardly possible to speak of serious earnings with a margin as small as this.
Surebets with unlimited yield are published on the website of a free surebet scanner BMBets.com. The main advantage of this resource is that it is free. Nevertheless, we would not recommend using it to make money from betting. Their scan speed is low compared to fee-based scanners and it is not enough for proper work with surebets. Surebets are visible to much more players as compared to fee-based resources, which greatly increases the risk to be banned by bookmakers.
