Great Suits

Fantastic suit - I’ve used the 5mm for several years. I’m 5’10 and 165 and it fits perfectly. I have a standard surfer build, and I’ve found there’s a bit extra room in the chest vs other companies that makes a huge difference for benign able to breathe well. It’s still snug but it’s flexible and has space in the right places.

I also have a 7mm and that’s kept me snug and warm in 44 degree water for a couple hours. Been out in 48 degree water for 4 hours. Great suits.

Amazing service and great shafts!

Natalie saw that I accidentally ordered two different size shafts for my speargun and gave me a call to make sure I was getting what I needed before shipping it. It was a Friday evening and they went the extra mile! The shafts arrived and were great quality!

Glad they were able to quicky remove and replace the old bent shaft. They work just as good on fish as well.

Awesome fins and excellent customer service

Needed a new pair of fins in a pinch before a trip and Blue tuna team came through big time. They had these fins in stock and were able to ship them out that day and they arrived the next day in time for a trip I was going on. These fins get the job done and are smooth, quiet and efficient. Really appreciate Matt, Nat and blue tuna team for their execution and always having the best quality gear in stock.

I've shot mine 100 times, many of them being into old dead coral. The tip is still in great shape and no signs of damage to the shaft. Also, I really like the 3rd sharkfin for repositioning my hands when drawing the bands.

Orca 90

Spearfishing out in Hawai'i. I've had the Orca 90 for about 4 months. It is my first speargun and I can say I have no regrets purchasing this gun. It works great, it is easy to use, and the design is solid. I took three fish my first day out and have taken dozens since. The largest being a 17" palani, which is a pretty broad fish. The 16 mm bands the gun comes with are very powerful. So much so that I only used 1 band for the first month. I absolutely love the spear the gun comes with. The 3rd sharkfin allows me to pull the band 2/3 of the way and then reposition my hands to draw the rest. I have also used the 3rd fin with a single band to reduce the power when shooting into a rock hole. Great gun, I recommend it!

Heavy duty

High quality slip tip, has the weight to tackle large pelagics. I purchased this slip tip because of the high quality spectra, I’ve lost 2-3 slip tips and fish because of cheap spectra cutting.

It makes my Bluewater gun easier to load. One note, if dropped in the water, it floats slightly underwater; making it easy to lose.
