15/27
The 15/27 series combines long-range performance with configuration versatility - it is our only long-range model available in the compact MINI form factor along with PRO and PRO USBL. Optimized for slanted and vertical transmissions, these devices are well-suited for long-term seafloor deployments.
Form Factor(s)
PRO
The largest and most powerful modems in the EvoLogics range. PRO models offer the highest transmission power and the widest selection of configuration options and add-ons. The series features our full range of models, including low-frequency, long-range, deep-rated devices for deep-sea deployments.
PRO USBL
PRO USBL transceivers are full-fledged PRO modems with a USBL antenna, enabling simultaneous positioning and advanced data delivery.
MINI
Compact and lightweight without compromising on performance. MINI modems match PRO-series transmission power in a smaller form factor. Ideal for space-constrained setups, TINY series features high- and mid-frequency models and offers key configuration and add-on options.
