Dang, such a bashing!! Now c'mon - from almost every MFG/Mkng Dept I've dealt with (SCUBA related or not), hedging #'s and claims is commonplace. Sure, some are more realistic than others. But who's to say the MFG of the Bladefish 5000 DIDN'T get 1 diver/snorkeler to get up to 3.5MPH at some point on some dive? Do YOU know for sure? NO! So let's stop the bashing with all the "I know this, you don't know that, they're claiming bulls**t, etc.". We weren't there for the testing, how they tested, what they used to measure speed with, etc. Only the MFG knows. And as far as their claim:
But the manufacturer claims they actually *Exceed* the performance of "heavier and more expensive" scooters.
Well, isn't just about EVERY other scooter out there heavier and more expensive? So if the Bladefish 5000 exceeds just ONE of those other scooters, then the claim above is valid. It's called semantics, a common part of marketing. Now, if they claimed it exceeded ALL scooters...another story.
Of course the 5000 will in no way be a replacement for tech scoots, or even some needs for non-tech. But it sure seems like a very good alternative for the recreational diver and instructors (IE, me). Let's be realistic in the general SCUBA market, if Joe Diver is given the choice of ALL scoots, the Bladefish (IMHO) would sure seem like a top choice - small, lightweight, easy to travel, etc. Sounds like a good marketing plan to me. And from the reports from people who have actually used it, it seems worthy! My concern is battery lifetime (not per charge, but when the batteries fail). Being they seem to not be user replaceable...that's my only red flag so far - in the scheme of how good they are for general users. Maybe they can be user-changed, or maybe they last 1000 charges. Only time will tell how that goes.
For me, I think I'll get one. I don't need to be carrying a 35-100lb behemoth (compared to the 5000) to do some nice recreational diving. And especially when teaching a DPV class.
