I had to buy myself a crimper after seeing this one.
Came with cutters, a seal rebuild kit, and gloves! Lol
Goes to 2/0.

Yah that's the better tool. The iWiss long handle crimper does not handle the geometry properly for really clean crimps.
If the ferrules are not sized for the wire correctly, such as stainless ferrules, vs aluminum ferrules, vs copper ferrules, the diameter of the crimp might need to be performed in stages. You might need the dogs for the SAE and the Metric sizes to crimp correctly.
Choose your crimper wisely, unless you buy the $$$$ version for every standard size you crimp.
The iWiss long handle wire crimper for 6ga to 2/0 is a fail, in my opinion.
The angle of the crimp squishes the material of the ferrule out the other side and forces you to re-crimp to compress the ejected ferrule back into the crimp.
It's not holding weight, and it's not right, so it will work for now and will be replaced.
The only issue with the hydro units is the age of the o-rings from Hunan.
No telling how old these are in the pump units. Most likely years out of date of the rubber seals, despite the lube in the cylinder.
If they use proprietary o-ring sizes, you'll need metric o-ring cord and super glue to fabricate your own new seals from modern made materials.
Took a chance on the long handles and not impressed.
Finding usefull non-out-dated o-ring cordage or HEI fuel line hose:
Priceless.
