We are a small county and like everybody else we are short-handed during the day, so we started pre-connecting piercing nozzles to buy us a few minutes until we are able to get the two-in-two-out. It has worked out great for us, especially on trailer fires. Most of the time we can put a trailer fire out and not even go in except to overhaul the fire. It's a great concept that a lot of volunteer fire departments could use, especially being short-handed. We also use it on house fires by using it to go through the roof to knock out attic fires. The spray pattern on piercing nozzles are great.
