310 pounds for the cross flow V4. The powerhead alone is 185. BRP has a website that has the specs for the newer models.

Unsure what you are looking for. The term "Powerhead" is used with specialized firearms used against sharks by divers. Sometimes known as a "bangstick", the powerhead is a single shot firearm, mounted on a long stick. When shoved hard against a shark, it fires a single cartridge.

Yes, you most definitely want a powerhead in your aquarium. Depending on what size aquarium and type of fish, you may want/need more. If you have any other questions please e-mail me at kiefersww@ymail.com

The very long shaft that the powerhead is mounted on, which makes it unsuitable for use as a weapon.
