Out of 114 posts I think only 2 or 3 of us have used the
BladeFish 5000 tho
deeperthoughts has a couple he's going to tell us about. It would be a good replacement for the Sea-Doo but like anything there are pros and cons and it is pricier than say the GTI or VS Supercharged
Here is my review from earlier in the thread(with a few edits/updates)
Pros:
Compactness: At only 10 pounds and small footprint it's a slam dunk for airplane travel-and I don't think TSA would have a problem with it(doesn't look like a torpedo) and amazingly light and portable for shore diving(finally, a piece of scuba gear that's user friendly out of the water)
Power: It will easily tow a diver with full gear
Run Time: between 1-2 hours and quick recharge(comparably)
Battery: Small Lithium Ion batteries don't take up space on unit-and you don't need to worry about charging them every few months
Battery Indicator Light Extremely bright and easy to see
Ease of use Very hassle free-plug in to charge-unplug and go -that's it(don't forget that plug tho)
Cons:
Noise: It's pretty loud-because it's a very small scooter there isn't much room for sound insulation
Battery: Can't switch out those Lithium Ion batteries-you'll need to wait for it to recharge before your next dive-and after about 500-1000 dives the scooter is dead-tho I've heard you may be able to send it in for battery replacement
Ergonomics:Not to bad but less fluid than a torpedo type scooter
Bottom Line: Look, the BladeFish just isn't going to replace torpedo shaped scooters but If space is a real issue, if you love shore diving but hate carrying your heavy scooter or if your a frequent traveler the BladeFish is definitely worth taking a look at.
