A betting finder (also called a betting scanner or oddsfinder) is a tool that scans odds across multiple sportsbooks and surfaces opportunities you would miss betting manually. Instead of opening nine bookmaker tabs and comparing prices one event at a time, a betting finder does it for you in real time.
At its core, a betting finder does three jobs in parallel:
1. Pulls live odds from every sportsbook it's connected to (DraftKings, FanDuel, BetMGM, Bet365, Pinnacle, Caesars, BetRivers, Bovada, BetOnline and similar).
2. Compares prices on the same event across those books, line by line.
3. Flags opportunities when the spread between books is wide enough to be profitable — either a guaranteed arbitrage, a value bet, or simply the best available odds.
A good betting finder refreshes every few minutes because sportsbook lines move constantly as bets are placed and news breaks.
The terms are mostly interchangeable. You'll see all three in search results:
| Term | What people mean |
|---|---|
| Betting finder | A tool that helps you *find* good bets across books |
| Betting scanner | Same idea — *scans* the market for opportunities |
| Oddsfinder / odds finder | A play on the brand name OddsFetcher, but used generically for any odds-comparison tool |
If you search any of these terms, you'll get the same category of sites. OddsFetcher is one of them — a free, real-time betting finder comparing 9 sportsbooks.
Not all betting finders are equal. The features that actually matter:
Most paid scanners charge $30-$300 per month for a marginally faster feed or a couple of extra books. The free tier from OddsFetcher covers everything most bettors need:
If you are starting out, the free tier is the right place to begin. Premium plans become worth it only when you are running enough volume that a few extra basis points of edge on each bet compounds into meaningful profit.
OddsFetcher is a free betting finder / betting scanner that:
1. Pulls odds from BetMGM, DraftKings, FanDuel, Bet365, William Hill, Pinnacle, Unibet, Caesars, and BetRivers.
2. Compares the same event across all 9 books in real time.
3. Surfaces three categories of opportunity:
- Sure bets (arbitrage) — combined implied probability under 100%, guaranteed profit.
- Value bets — odds that imply a lower probability than the market consensus, indicating +EV.
- Best odds — for any given event, the single best available price on each outcome.
4. Refreshes every 5 minutes.
The whole tool runs in your browser; there is no software to install and no API key needed.
When books disagree on probabilities enough that the combined implied probability on all outcomes drops below 100%, you have a guaranteed profit. Example: FanDuel 2.10 + Bet365 2.10 on a two-way market = 95.2% combined probability = 4.8% locked-in profit regardless of who wins.
When a book offers odds that imply a lower probability than the true chance of the outcome, you have positive expected value. Example: the market consensus on Team X is 50% (2.00 decimal) but one book offers 2.20. That is a +EV bet — you will profit over hundreds of such bets even though individual bets will lose.
Even when there is no arb or value edge, the best odds in the market beat the average by 1-3%. Over 500 bets per year, simply always taking the best available odds adds 2-3% to your expected return.
1. Open the OddsFetcher scanner. No sign-up required.
2. Filter by sport to focus on markets you know (or browse all).
3. Look for hot opportunities — anything with 5%+ profit on the sure-bet side, or 3%+ overvalue on the value-bet side, is worth investigating.
4. Check the legs — every opportunity shows exactly which book and which price, so you can place the bet without doing math.
5. Place both legs quickly — arbs disappear as books rebalance. Speed matters.
6. Track results — log every bet, the odds, the stake, and the outcome. Over hundreds of bets, a real edge becomes visible.
Yes. Odds comparison and arbitrage are legal in most jurisdictions. The bets themselves are placed at licensed sportsbooks. Some books may limit or close accounts that consistently exploit arbs, so bankroll management across multiple books matters.
Arbitrage opportunities, by definition, do — combined implied probability below 100% means every possible outcome yields a positive return. Value bets are profitable over time but not on a per-bet basis. No tool can guarantee a profit on a single bet you choose manually.
OddsFetcher refreshes every 5 minutes. For active bettors, checking 2-3 times per day during peak hours is enough. For arbs specifically, the moment an opportunity appears is when it's most valuable — speed matters more than volume.
You don't need an account to *see* opportunities, but you do need accounts at the books involved to actually place the bets. To capture every arb or value bet, having accounts at all 9 books OddsFetcher tracks is the standard setup.
An odds converter is a one-off calculator that converts American / decimal / fractional odds. A betting finder is a real-time scanner that compares odds across books and surfaces opportunities. OddsFetcher includes a free odds converter alongside the scanner.
Yes. OddsFetcher is free, with no sign-up, and covers 9 bookmakers. The free tier includes sure bets, value bets, and best-odds comparison.
