All other indoor Helium HNT miners on the market currently come with 2dbi antennas. In contrast, Bobcat Miner 300s enhanced 4dbi antenna is able to provide 150 percent wider coverage (up to 10+ miles). * Quad-core Processor Unlike all other HNT hotspot miners on the market that run on Raspberry Pi, Bobcat Miner 300 uses the industrial-grade Rockchip PX30, a high-performance quad-core application processor designed for high-end commercial applications. This offers unmatched reliability and direct manufacturer support especially when it comes to debugging. * Built-in 64GB eMMC flash for better data security and larger memory storage. All other Helium HNT miners on the market either use 32GB flashes or external SD cards. More memory means the miner is able to compute more at the same time, as well as longer device life expectancy (up to10 years), because it allows 3000 write cycles, compared to 500 write cycles allowed by an SD card
