100% arrow stop!!!

The Strong Block 2 stops simply every arrow. It has got maximum stopping power over the entire disk surface. The disc is 25 cm (9.8 in) strong and consists of a combination of target foams 400 and 600. This proven combination stops every arrow dynamically and safely.
 
Even the strongest crossbows and compound bows meet their match in the Strong Block 2!
Strong Block 2 Dimensions: approx. 600 x 600 x 250 mm (23.6 x 23.6 x 9.8 in)
Material: TF 400, TF 600
We highly recommend this disc for traditional bows up to 60 lbs draw weight. For compound bows and crossbows, due to the bundled impact, we recommend the HP disk 100.
