SL1500 (0.2 to 20-m range)
The original (and our most popular version of the Argonaut-SL) gets a big makeover with a sleek new housing and new features. In addition, dramatic improvements have been made in reducing the minimum measurable distances on both the vertical beam (level) and horizontal beams (velocity) that allow the SL1500 to work in smaller channels than the previous Argonaut-SL.

• Profile has been halved to a very small 7.8 cm (3.1”).
• Incorporates the new SonTek TrueCompass/Tilt sensor as a standard part of the package.
• New, reduced size, 8-pin connector.
• Mounting plate is integral to the unit. It can be flat-mounted to a wall, or it can make use
of U-bolts for attachment to vertical pipes.

Features
• Water Velocity and Level
• MultiCell Current Profiling
• PowerPing Hi-precision Sampling
• Mounting and Display, and I/O
• Velocity-Indexing Software

Designed specifically for side mounting on bridges, canal walls, or riverbanks, the SL’s SLEEK low-profile housing makes installation easy. With three models to choose from, the SL can be used in channels as small as you can jump across to rivers as wide as the Amazon.

Ultra narrow beam widths combined with unmatched side lobe suppression provide the SUPERIOR acoustic directivity necessary for achieving maximum horizontal range free of interference from surface or bottom boundaries.
