You can already find a few videos about Diana Trailscout on YouTube. It’s been on the market for some time now. The rifle received really good reviews. Now it’s time for me to take a closer look at the CO2 air rifle.

Special features of Diana Trailscout

Diana Trailscout pierces simultaneously three 12-gram CO2 capsules. This provides an output of about 100 – 110 shots. When I did some research, I saw even higher numbers, but I can’t confirm them from my own experience. If any of you own a Trailscout, I’d love to hear your experiences.

A nice feature of Diana Trailscout is that you can adjust the piercer to match the capsule’s length. These have often different sizes. Therefore, 12-gram CO2 capsules from different manufacturers can also be used. Once you have found a brand with which your Trailscout works reliably, you should stick with it. I’ve read there are problems with some brands and that they get stuck. Fortunately, I didn’t have these problems with the capsules from GSG that I still had at home.

Diana Trailscout can be equipped with a rifle scope on its 11 mm prism rail. Alternatively, you can also attach a reflex sight there. If you don’t have any optics available, it’s also possible to aim via the open sight.

Great trigger

A big plus of Diana Trailscout is the excellent Diana Improved Trigger (DIT). It is well adjusted ex works; however, the pre-travel and trigger weight can be readjusted.

A good trigger is extremely important for the accuracy when shooting. If you have a well-defined trigger pull and the trigger weight isn’t as high, there’s much less chance that you’ll miss when you pull the trigger.

The DIT is one of the biggest advantages of the CO2 rifle.

Before you can fire the shot, you have to deactivate the manual safety. Once deactivated, you can then shoot until you push the pin back in to reactivate the safety. Then the trigger blade is locked again.

My conclusion of Diana Trailscout

Trailscout is an affordable rifle to have fun with. Especially the trigger contributes significantly to the good shooting result. The CO2 rifle is light and handy.

The magazine is sometimes a bit notchy. But since I’m a fan of the single-shot adapter anyway, that wasn’t too big of a problem for me.

100 – 110 shots is really good. If you still don’t have enough, you can quickly change the 3 capsules. However, you should wait 5 minutes after piercing the capsules. The rifle does cool down significantly, something Trailscout doesn’t like. Just take a short coffee break and then you can continue.

Did you guys ever get a chance to shoot a Trailscout?

I hope I entertained you for a few minutes.

There will be another post next week!

Have a good time!

Best wishes!

Yours, Andi

  1. Schönen guten Tag, ich habe das Trailscout vor ein paar Tagen bekommen. Mein Problem ist, dass bereits alle 2 mitgelieferten Dichtungsringe gerissen sind und das schon nach ein paar Schuss (vllt 20).
    Unschön daran ist natürlich, dass dadurch 12 Co2 Kapsel direkt für den Müll waren.
    Den Stößel der Co2 Kappe hab ich auch schon verstellt und wieder nach 20 Schuss kam der Dichtungsringe raus.

    Könntest du mir da vielleicht helfen?
    Mfg Jens

    1. Hallo guten Morgen Jens,
      danke dir für deine Nachricht! Wow, das ist ja super ärgerlich.
      Ich hab da aber keine perfekte Idee oder Lösung für dich leider. Ich empfehle dir, dich mit dem kurz zu schließen. Die sind Hersteller und Distributor für die Diana Pistolen und Gewehre. Die können dir sicher da weiter helfen.
      Ich drück dir die Daumen, dass das schnell gelöst ist.
      Liebe Grüße
