The Humminbird HELIX ICE Conversion Kit (740202-1) turns your existing HELIX 7, 8, 9, or 10 CHIRP fish finder into a complete ice-fishing setup for one season’s investment – no need to buy a separate dedicated ice unit. The kit includes the premium shuttle (master power switch, quick-connect SAE power cables, large carry handle, multiple 1/4-20 accessory mounts, two rod holders, cable management, battery compartment with cover), a Dual Spectrum CHIRP ice-specific transducer engineered for the small ice-hole footprint and cold-water performance, and the mounting hardware to put your existing HELIX head unit into the shuttle. One-year limited warranty. Battery and charger sold separately.
The Humminbird HELIX ICE Conversion Kit is the right answer for HELIX CHIRP fish finder owners who want to fish hardwater in the winter without buying a separate dedicated ice unit. The kit takes your existing HELIX 7, 8, 9, or 10 CHIRP head unit (the same head unit you already use on the boat in open-water season) and gives you the shuttle, the ice-specific transducer, and the cabling needed to deploy that head unit on the ice for winter fishing.
What’s in the kit. The premium ICE shuttle (the carrier that holds the HELIX head unit, battery, and accessories together as one portable ice-fishing unit), the Dual Spectrum CHIRP ice transducer (the ice-specific transducer with the small footprint to fit through an 8-inch ice auger hole), quick-connect SAE power cables (so you don’t permanently wire the boat-side power leads), and all mounting hardware. What’s NOT in the box: the head unit itself (you already have it – that’s the point of a conversion kit), and the battery and charger (sold separately because the right battery / charger combo varies by how long you fish per trip).
The premium shuttle features. The shuttle itself isn’t just a carry case – it’s a mobile mounting platform with the features that matter for serious ice fishing. The master power switch on the shuttle face means you can power the head unit on / off without unplugging anything (saves battery between holes when you’re walking from one drilled hole to the next). Quick-connect SAE power cables: the head unit plugs into the shuttle’s internal cabling via the SAE connector, and the battery plugs into the shuttle the same way – so swapping batteries between trips, or moving the head unit back to the boat in spring, is a tool-free job. The large carry handle is engineered to be glove-friendly (you can carry it with thick winter gloves on, doesn’t dig into your palm with the head unit’s weight loaded in). Multiple 1/4-20 threaded accessory mounts on the shuttle’s top and sides accept standard accessory mounts (a flashlight, an action camera, a secondary GPS unit, whatever the angler wants to add). Two rod holders are integrated into the shuttle – so the rods you’re using ride on the shuttle and don’t lay in the snow. Cable / transducer management keeps the transducer cable from tangling around the auger or the angler’s feet (a real annoyance on a long ice-fishing day). The battery compartment has a snap-fit cover that keeps snow / slush / spray out of the battery terminals.
Dual Spectrum CHIRP ice transducer. The ice transducer is the meaningfully different component versus your boat-side transducer. The form factor is much smaller (small enough to drop through an 8-inch auger hole), the cable is silicone-coated for cold-weather flexibility (a stiff PVC cable cracks at 0 degrees F), and the float / weight design is ice-specific (sits at the right depth in the hole, doesn’t drift on the cable). The transducer covers Dual Spectrum CHIRP – the same wide-band CHIRP technology as the open-water HELIX transducers – so target separation, fish detection, and bottom-tracking work the same way under the ice as they do on the boat. The transducer is engineered specifically for HELIX CHIRP head units (Humminbird’s CHIRP signal-processing format), so the conversion is true plug-and-play.
HELIX CHIRP head unit compatibility. The kit fits HELIX 7 CHIRP, HELIX 8 CHIRP, HELIX 9 CHIRP, and HELIX 10 CHIRP head units. The shuttle is sized for the typical screen / housing dimensions of the HELIX line, and the cabling matches the HELIX power and transducer connectors. NOT compatible with non-CHIRP HELIX models, with HELIX MEGA-only models, or with the HELIX 12 / 15 (those are too big for the shuttle’s mounting bracket). Check the specific HELIX model number on your existing head unit before ordering.
Why a conversion kit (versus a dedicated ice unit). The conversion kit costs meaningfully less than buying a brand-new dedicated ice fish finder, and uses the head unit’s electronics, charts, GPS waypoints, and history that you’ve already built up over open-water seasons. If you fish hardwater 5-10 times per winter and you’ve already got a HELIX CHIRP for the boat, the conversion kit is the right call. If you fish hardwater 30+ times per season and want a permanently configured ice setup so you don’t have to swap the HELIX between summer and winter use, then a dedicated ICE HELIX (separate head unit) makes more sense. The conversion kit’s break-even versus the dedicated unit is around 5-10 winter trips for most anglers.
Cold-weather durability. The shuttle materials and the transducer cable are engineered for cold-weather marine service – it doesn’t crack, doesn’t get brittle, and the connectors don’t fail in the typical 0 to 30 degree F ice-fishing temperature range. The shuttle’s IP rating handles snow / slush / spray exposure (the typical conditions on an ice-fishing trip). The battery compartment cover keeps moisture off the battery terminals so you don’t get corrosion buildup over the winter season.
Made in USA. Humminbird manufactures the conversion kit in the United States, which means tight quality control on the shuttle assembly and the transducer manufacturing. For a piece of gear that will see brutal temperature extremes and rough handling, the made-in-USA quality is meaningful versus offshore-manufactured ice gear that often shows quality issues in cold-weather conditions.
Install. Tool-free for most steps. Place the HELIX head unit in the shuttle’s mounting bracket and tighten the included thumbscrews (no tools required). Connect the head unit’s power cable to the shuttle’s SAE quick-connect (snaps in – one motion). Connect the transducer cable to the head unit’s transducer port (uses the head unit’s standard connector). Drop a 12V battery into the shuttle’s battery compartment, connect the battery’s SAE cable to the shuttle’s power input. Close the battery cover. Total setup time is typically 10-15 minutes the first time, 2-3 minutes for subsequent trips after you’ve done it once.
What you’ll need to add. A 12V deep-cycle battery (the typical ice-fishing choice is a 7-12 Ah lithium – light, high capacity, performs well in the cold) and a charger appropriate for the battery type. Battery and charger are sold separately because the right combo depends on how long you fish per trip and how many trips per season. For typical use, a 9 Ah lithium battery and a smart charger is the standard combination.
One-year limited warranty. Standard Humminbird warranty terms apply (covers manufacturing defects under normal use, doesn’t cover physical damage from drops or impact). Order before 3 PM ET for same-day shipping on in-stock units.
