Oros Strike Indicators Review- Are They Really The Best?

Oros are a new indicator that hit the market recently. They have quickly spread in popularity, and are now one of the best selling strike indicators.

Oros vary in design from other available indicators. They screw apart, and inside there is a slot to lay your leader in. This is very similar hardware as the Airlock indicators, except on the Oros it is internal. Once you lay your leader in the slot, simply tighten the indicator and start fishing. Oros do not kink your leader, and allow for quick adjustments on the river. However, they are more expensive than other indicators.

Whether you love them or loathe them, Oros are here to stay. I think most nymph anglers can definitely benefit from using one. I have been using them for a couple months now, and I don’t see myself going back to a Thingamabobber.

This article will cover the pros and cons of Oros indicators. If you haven’t used them, they are worth checking out.

Although strike indicators are just bobbers for fly fishing, some are better than others. I get picky with my indicators, so here is an honest review of the Oros system.

Pro – Oros Are Very Adjustable

To adjust the Oros, simply loosen it a bit (not all the way). Then, you can slide it up or down your leader. Once you have adjusted it, just tighten it back up and start fishing.

With Thingamabobbers, you have to undo the loop, which kinks your leader. Then, you must redo the loop in a new spot, which also kinks your leader.

Oros are extremely easy to use, and you can adjust them in just a few seconds. If you encounter a deep nymph hole, you can move the Oros up your leader quickly – this equates to more time with your flies in the water.

Pro – Oros Do Not Kink Your Leader

Other indicator systems leave memory in leaders, because they kink the material. This is especially true for Thingamabobbers and Corqs. Once a leader is kinked a few times, it is tougher to use because it’s all twisted.

By using Oros, you can make your leaders last much longer. They preserve the life of your leaders, so you won’t have to buy as many. Leaders are not that cheap, and they are getting more expensive. It is better to make them last than to buy new ones.

Pro – Oros Are “In Line” With Your Leader

Other indicators have the attachment point on the top of the indicator. Thingamabobbers, Airlocks, and Corqs all have the attachment point at the top – This makes casting a bit more sloppy, as it throws the balance off with your nymph rig.

Since the Oros hardware is internal, it is perfectly in line with your leader. This keeps your rig more balanced, and it is easier to cast.

One of my favorite parts about this: when your flies have sunk deep enough, the Oros will turn, and your leader will stick out the top vertically. This lets you know that your flies are in the zone, and they have sunk deep enough.

Con – They Cost More Than Other Indicators

Oros indicators are not cheap. They are about $3-4 a piece, and they are expected to increase in price. This is more than a $2 Thingamabobber or Corq indicator. Although $3 isn’t a lot, they are still considerably more than normal indicators – 50% more.

However, given their performance – I think the price is justified. They are also very durable, so you won’t go through that many. I have had some last for months on end.

Con – They Will Scuff Your Leader

Although they won’t kink your leader, they will scuff it. When you slide the Oros to adjust it, it scratches your leader each time. After many adjustments, your leader will look pretty scuffed. This isn’t a huge deal, because fish aren’t looking at the butt section of your leader – but it can still be annoying.


Overall, I think Oros are worth purchasing. They are the best indicator system I have found, and they really help you spend more time with your flies in the water. The adjustability is top notch, and I have not seen a better indicator since the New Zealand system. If you want to stop fumbling around adjusting your nymph rig, consider using an Oros.

If you haven’t tried them out, consider picking up a few. They have been selling out quickly, as Oros is trying to keep up with demand. They are available at most fly shops, as well as online.
