At first I regretted my decision after not being able to load the band more than half way. The shaft was also thicker and heavier than I had hoped. After watching countless videos on the internet I learned that this Gunn can take out some serious fish, and if you load it right it's not that hard! You need to load it high on your chest plate somewhere between your collar bones and your abs. As you pull the band to you move the butt on the chest plate and grab the second. In a triangular motion load the band. If you are afraid of the gun, or dont have it on your high chest, it will be extremely hard and painfull to load. ### ⭐⭐⭐⭐⭐ Best gun for the $ *by J***N on April 10, 2020* I have the 150 and it’s an awesome gun! I also have extremely expensive guns and always go back to this. It’s easy to load is you have any strength and the correct technique. This isn’t a gun for a first time spearo. Learn with something else and work your way up to these powerful highly accurate cannons. The 150 is a must in my book I take big fish and smaller fish with long shots and it puts more fish in the box. I use mine 1-4 days a week for years and it keeps on doing the job. ### ⭐⭐⭐⭐⭐ Also to my surprise I'm not nearly as strong as I like to think I am as this bad boy is ... *by L***N on May 26, 2018* Was on the plane to Maui and I ordered The 90 cm last minute after reading a positive review online. To my surprise it arrived much sooner than expected. Also to my surprise I'm not nearly as strong as I like to think I am as this bad boy is incredibly hard to load. I've only managed to get one band loaded so I figured it would lack power. Regardless of the single band my gun struck my first fish with unreal power and accuracy. Thank you to Rob Allen and The House of Scuba for an amazing experience. 10/10 would buy again --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/14403859-rob-allen-aluminum-tuna-railgun-speargun-with-open-muzzle-all](https://www.desertcart.co.th/products/14403859-rob-allen-aluminum-tuna-railgun-speargun-with-open-muzzle-all) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-28*
