Airmar CHIRP transducers are made with cables ending in a bare wire connection. Some sounders have internal terminal blocks to which these bare wires can be connected, but many CHIRP fishfinders and sounders use brand-specific connectors.
These splices are available in two models, one for wires with up to 6 conductors and one for wires with up to 10 conductors. Both models have waterproof gland fittings rated to IP67. A 1.3mm hex-head wrench is included.
Connection kits are available with an inline splice plus a brand-specific connector on a cable pigtail.
These in-line splices can also be used to connect two wire segments for non-CHIRP transducers.
Airmar makes an adapter box for Raymarine CHIRP applications, and Garmin makes its own adapter boxes for use with its blue 8-pin and orange 12-pin connectors.
