Reddit mentions of The Accessory Pro Removable Floaty + Anti-Fog Inserts compatible with all GoPro cameras

There are a couple factors that you need to take into account when choosing a telescoping pole mount:

• Application (underwater, outside window while driving, walking, etc)
  
• Maximum (fully extended) length
  
• Portability (fully collapsed length)
  
• Price
  
  I did some research and ended up trying a couple different products, and I'll share my thoughts on each one with you.
  
  ----------------
  
  XSories Big U-Shot
  
  | Min (Collapsed) Length | Max (Extended) Length | Weight | Price |
  |:-:|:-:|:-:|:-:|
  | 8.75in (22.23cm) | 37.75in (95.89cm) | 4.1oz (116.23g) | $39.99 |
  
  Pros:
  
  
• At ~9 inches, the XSories Big U-Shot is almost small enough to be pocket sized. I actually put it in my swimming trunks pocket and used the included carbiner to clip the bottom of it to a belt loop (yes my swimming trunks have belt loops) to prevent it from falling out. It ended up being fairly comfortable while sitting on a jetski.
  
  
• The extension locking mechanism allows for quickly readjusting pole length.
  
  
• With a max reach of 37.75 inches, you can easily fit yourself and a bunch of your friends into a nice selfie - and depending on the angle you use, you won't even see the pole.
  
  
• The pole is light enough to float with an attached ProFloaty (3rd party floaty with attached tether).
  
  Cons
  
  
• This is not meant for shooting in or around water. I took it on the ocean for one day, and all of the metal in the ball head noticeably oxidized.
  
  
• The locking mechanism seems cheap and flimsy, you basically pull out a section and twist it to the side and it seems to lock with friction.
  
  
• Maybe it's because I over tightened the tripod mount, but the little clear disk under the 1/4" screw started cracking after about 3 uses, and will likely fall off shortly. This confirms my suspicion that the entire ball head on this one is a bit too fragile.
  
  
• Due to it's light weight I'm a little concerned about holding it out the car window while going 80mph.

  Sealife Aquapod
  
  | Min (Collapsed) Length | Max (Extended) Length | Weight | Price |
  |:-:|:-:|:-:|:-:|
  | 18in (46cm) | 53in (135cm) | 9oz (255g) | $69.95 |
  
  Pros:
  
  
• At 53 inches you can get really up close and personal with wildlife, or capture some nice faux-flyover footage.
  
  
• The construction of this thing is strong and I would not hesitate to stick it out the window going 80mph.
  
  
• Firm locking mechanism.
  
  
• Comes with standard 1/4" inch and GoPro attachments, so you don't need the extra tripod mount. In addition, the attachments are quick release, so you can easily remove and put back the GoPro as needed.
  
  
• The Aquapod is made to be used underwater, so you don't need to worry about rust / oxidation.
  
  Cons
  
  
• When completely collapsed to 18 inches, it is far from pocket-sized and won't fit into just any backpack. Your best bet would be mounting it on the outside of your backpack/bag.
  
  
• The Aquapod is noticeably heavier than the other poles, which says something about its durability. At the same time, it takes a significant amount of strength to hold it, especially when fully extended.

  XSories Big U-Shot 2.0
  
  | Min (Collapsed) Length | Max (Extended) Length | Weight | Price |
  |:-:|:-:|:-:|:-:|
  | 11.45in (29cm) | 37in (94cm) | 4.94oz (140g) | $49.95 |
  
  Pros:
  
  
• With a max reach of ~37 inches (same as the original Big U-Shot), you can easily fit yourself and a bunch of your friends into a nice selfie - and depending on the angle you use, you won't even see the pole.
  
  
• 100% stainless aluminium ball-head feels sturdy and will not rust.
  
  
• The U-Shot 2.0 is made to be used underwater, so you don't need to worry about rust / oxidation.
  
  Cons
  
  
• Has the same extending/locking mechanism as the original U-Shot which I'm not a huge fan of.
  
  
• Feels a little flimsy when fully extended, but still better than the original U-Shot.
  
  ----------------
  
  The XSories Big U-Shot and XSories Big U-Shot 2.0 both come in non-Big variants, but I feel they are too short to even be considered.
  
  ----------------
  
  I think I'm gonna end up getting rid of the Sealife Aquapod and the original XSories Big U-Shot and keeping the XSories Big U-Shot 2.0; it's portable, extends enough to capture nice footage / get wildlife closeups and is meant to be used underwater so no worries about rust and corrosion. I really wish there was a hybrid between the XSories Big U-Shot 2.0 and Sealife Aquapod, but until then I hope my breakdown will help you in making a decision.

I've been using this thing as a floaty its been good for river trips and cliff jumping and whatnot.

You could also get this offbrand one, it comes with adhesive to stick it to to any back.

This is a floaty with a tether on it. I'm also getting a tether for other uses.
