I live in New Jersey and most of our spearfishing is on jetties/rocks and wrecks. vis is generally <20ft. I currently use a small JBL but it lacks the penetration I need for shots over 6-7 feet. I was either thinking of upgrading to the JBL sawed off Magnum XHD or trying an OMER HF2 80cm. Both seems nice...and I know they are two totally different guns. Can anyone sort out the pros and cons based on experience?
