English Arbs cannot be worse or better; they are found by the same scanner tools according to given algorithms.
But, as a rule, scanners reduce the functionality of free sure bets compared to paid sure bets.
For example,
- Delays in scan results of 15 minutes or more are quite common. Given that many forks disappear within 5-10 minutes of detection, you will therefore receive alerts for many forks that no longer exist.
- Limited rate of return on arbitrage. Arbs displayed for free are usually limited to profit margins of 1% or less. The most profitable sure bets are hidden, meaning that you can only bet on sure bets with a low return on investment.
- Limited number of bookmakers. While paid scanners will show you the odds of all bookmakers for a particular match, a free surebets program may just show you just a few of its choice.
- Restrictions on the type of bookmaker arbitration. In the free arbitrage bets search mode, middles and values are usually not displayed.
- Some scanners limit their free versions to just a few sports.
