No.

What is the purpose of the incendiary rounds?

hehehe I don't remember this episode.

Interesting explanation about why sailfish have bills from Do Billfish Use Their Bills To Help Capture Prey? | Guy Harvey Sportswear Blog .

Anglers have known for some time that that broadbill swordfish do in fact use their bills to help them secure a meal. For example, Southern California anglers have watched firsthand as swordfish cut their mackerel in half with a quick flip of the bill.

Marlin and sailfish, however, were a different story. There had long been a debate as to whether or not marlin and sailfish actually used their bills to stun and then eat a bait, or did they simply use their bills as a balancing mechanism to assist in their swimming motion?

When a marlin or sailfish rises in the spread and attempts to eat the trolled lure or rigged bait, the bill moves violently in that effort. Some have thought that the fish were attempting to hit the bait with their bill while others have speculated that the bill played no part in the effort and simply followed the movements and direction of the fish’s excited and hungry mouth. Even slow motion video of surface feeding billfish could not conclude this long standing debate.

Feeding sailfish as witnessed firsthand by Guy Harvey

This long standing debate ended during an underwater filming expedition where I was able to not only witness firsthand, but also film on different occasions both marlin and sailfish using their bill’s to stun and catch meal. It was a real thrill to witness off of Isla Mujeres using their extended dorsal fins to corral the bait into a tight school. It was an even bigger thrill to then watch the sailfish make a distinct motion with their bill to hit and stun the sardines and then circle back to eat them as they sank away from the school.

Handsome sloth. Who's the kid?

Unusual use for a light table, interesting.

Try a mask mount, it's great.

You're not using the best setting because there's vignetting in the corners. The best setting is the 1080 @ 127 FOV, there will be no vignetting, and objects will not look so far away.

The slip tip looks bent?

Good idea about the belt pocket.

Interesting, thanks.

Those are some nice hogs.

Whoa Emil's record is toppled! I didn't think that was going to happen for a very long time.

Nice bag but I wouldn't want fish together with my gear no matter how insulated. The spines will poke holes in it in no time anyways. The insulated part is probably meant for food and drinks.

That Armour fin bag was designed for Pursuit to my specifications, such as the straps being contoured around the neck area. Then the manufacturing cost turned out to be too high, and I did not want to buy from Armour. The Armour bag should be selling for around $120. Pursuit will be offering the same design with a few improvements, such as more padded material to protect the fins, for around $80.

Interesting fighter.

The Pursuit bags have been too long coming.

The GoPro HD HERO2 and flat glass lens compatibility issue is now fixed. Following is a description of the initial problem and the solution.

After extensive testing of the flat glass lens with the new HERO2 cameras, we found that the HERO2 camera lens may touch the housing glass flat lens during a dive, and put enough pressure on it to cause it to crack. The factors contributing to this are as follows:

• The camera lens of the HERO2 is slightly bigger than that of the original HERO HD.
• GoPro housings are not all made exactly the same. In some housings the distance between the camera lens and the housing flat glass lens is decreased.
• If the black bezel is screwed down with too much force it will also decrease the distance between the lenses.
• Water pressure pushes on the back door of the housing, which pushes on the camera moving it more towards the front of the housing and the glass flat lens. Enough pressure may be put on the glass flat lens to cause it to crack.

This has never been an issue with the original HERO HD as we did calculate the clearance to be safe. But now with the HERO2 camera lens being bigger the distance between the camera lens and the glass flat lens is reduced, and it can happen even at depths under 60ft that the camera lens is putting so much pressure against the glass flat lens that it will crack.

We came up with a fix for this problem and it is quite simple. A washer/spacer that is manufactured to our specifications is placed over the HERO2 camera lens and flush against the camera body. The spacer sits between the camera body and the inside front wall of the waterproof housing, preventing the HERO2 camera from moving into the housing too much, and the camera lens never touches the housing flat lens. This fix will work on both the regular housing, and the LCD with it's larger back door.

Both polycarbonate and glass flat lenses from Pursuit now come with a spacer included.

Spacer usage guide:

1. Gopro HD HERO2 and glass flat lens - Spacer must be used.
2. Gopro HD HERO2 and polycarbonate flat lens - Spacer is recommended although we've never had a problem with a polycarbonate lens breaking or deforming.
3. Gopro HD HERO and glass flat lens - Spacer is optional.
4. Gopro HD HERO and polycarbonate flat lens - Spacer is optional.
5. Gopro HD HERO 960 and glass flat lens - Spacer is optional.
6. Gopro HD HERO 960 and polycarbonate flat lens - Spacer is optional.

MSRP is $629.95.
