Si-Tex SVS-750

The Si-Tex SVS-750 is a rugged and affordable fishfinder and plotter.

Bench-testing the Si-Tex SVS-750, I found operation intuitive. Waterproof, it boasts big, easy-to-use buttons. Its vertically oriented screen allows it to fit in tight spaces. The slot for the optional C-Map card is sealed by a rugged, gasketed plug. $899;
