It's IPX8 rated. If a device has an IPX8 waterproof rating, it means that it can withstand continuous immersion in water. The testing conditions for the IPX8 are defined by the manufacturer, but the testing is always performed under more severe conditions than the testing for the IPX7 rating. This means that an IPX8 waterproof device can be submerged in water deeper than 1m (usually up to 3m/9.8ft) for more than 30mins and can still work properly.
Caveats are that it's STILL water. no currents, eddies or pressure changes. Also fresh water not salt. GoPro don't give an IP rating for the Max (assume IPX8 as they say 5m waterproof). Either way, salt, surf & sand will ensure your camera takes on water over time. Only bonus is that you can get a waterproof case for the Insta. Can't find one for the Max.
Westozwind, I'm with clayisland on GoPro having done a really good job at making the statement "Either way, salt, surf & sand will ensure your camera takes on water over time" two very different time frames for GoPro and Insta,..so far. My now almost 4 yr old Hero 7 has been slammed around in saltwater kiteboarding and kitefoiling since the day I got it with no issues. Maybe at some point it will fail, but 4 yrs and running is way different than 4 months, or 4 sessions and done..
I've thought about the dive case for Insta but the weight gain, video quality issues and fighting off condensation inside the case aren't appealing. I'll wait to see how the X3 survives without a dive case.
Speaking of weight, this is my lazy-quick-and-dirty Max mount for my Slicks. Just used stuff lying around the shop; epoxied wood dowel, thin wall slit pvc pipe and some thin bungee. Comes in at around 242 gms (155 for the Max and 87 for the mount). My DIY carbon boom is 300 gms, so the 360 cam rig brings the total to 542 gms. I weighed a Duotone aluminum boom at 580 gms, so it's sorta like going back to the aluminum boom weight with the camera mounted, although more rear weight bias.
I've mounted the Max right at the end of the boom; lightest weight and lowest effect on wing performance, but a less natural looking image. I've also mounted the Max about 40cm beyond the back of the wing (on my Echo's); best looking image but it really effects the wing performance (especially downwind luffing!). This is my compromise position. I'm sure there's a bunch of different, more elegant ways to accomplish the same goal.
