48/78
48/78 models achieve the fastest data rates across our PRO, MINI and USBL lines. They are available with several depth ratings, all of our form factors, and as PRO USBL transceivers for combined communication, navigation and positioning. From ultra-compact UUV integration to stationary long-term deployments, the series provides dependable communication and accurate positioning in demanding shallow-water environments.
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.
TINY
Ultra-compact form factor for size- and weight-sensitive applications. TINY series features our high- and mid-frequency models with balanced transmission power and a focused selection of basic configuration and add-on options.

Please note:
Specifications are subject to change without notice. Listed bitrate and operating range values refer to performance in good acoustic conditions and vary with the environment. Operating range and depth ratings depend on the selected product configuration.
Modems
The 48/78 family is available in PRO, MINI, TINY and PRO USBL configurations with multiple add-on options.
With its horizontally omnidirectional, donut-shaped beam pattern, the 48/78 is optimal for fast data transfers in shallow waters and between devices operating at similar depths.
