The RAM Double Spinner Target is made to last. Its 5mm thick plates are made to withstand most powerful impacts from airguns (>20J).
The target has two stands so that it can be easily put in the ground. For the best result, place the target at an angle to minimize the impact of incoming pellets and to make sure pellets are reflected downwards into the ground.
The larget target has a diameter of 9cm whereas the smallest one has a diameter of 5cm.
Disclaimer: Even though the target is relatively thick compared to most airgun targets, it can still break if shot with an airgun that is too powerful or after heavy use.
