The Lezyne Alloy HV Digital Drive 3.5 is a high volume floor pump with a 3.5 in digital gauge. It has a machined aluminum barrel and base, a steel piston, and a wood handle.
HV stands for high volume. A high volume pump has a wide barrel that moves more air with each stroke, which suits large tires that run at lower pressure, such as mountain bike, gravel, and fat bike tires. The tradeoff is a lower maximum pressure, here 100 psi (6.9 bar), so it is not the pump for narrow high pressure road tires.
Digital gauge: a 3.5 in digital display at the base reads tire pressure up to 100 psi (6.9 bar). A digital readout makes it easier to hit a specific low pressure
ABS-1 Pro Tubeless chuck: Lezyne's chuck at the end of the hose that connects the pump to the valve
Hose: extra long, nylon reinforced braided hose with aluminum couplers, so the pump reaches a bike in a stand or on a rack
