I have 3 boards for me and my 2 sons, having to pump all 3 before a session was bith time consuming and tiring albeit a good workout.
After much research on many paddleboarding forums I chose the Shark 3.
Whilst not he cheapest, you get what you pay for,
The build quality and aesthetics made me feel confident that the reviews had some merit.
I have 3 Hatha ( 10'6) boards. Just 4 mins from start to 15psi and all 3 board done around the same time as pumping up 1 to full pressure.
An absolute game changer.
Another huge bonus,, when packing away at the beach, the boards obviously get sand and dirt on them. In the past, we would get them.home, re inflate ( to get shape) so I could properly rinse and clean them, with the shark, this task is so much easier and less time consuming.
After demonstrating my pump to a friend, he has just ordered one.
A great product, my only criticism, it would be nice/useful to be supplied with a dedicated carry bag but im just being picky, ive bought a small ruc sack to accommodate it
