GT12M Bronze Thru-Hull - 350W - 20 Degree

Designed for reduced drag and optimum sonar performance on midsize fishing and cruising boats, this flush-mounted, 350-watt mid-band CHIRP transducer clearly defines fish arches, structure, and bottom depth returns on your display.

Midband Chirp Traditional Sonar

This 8-pin, 350-watt bronze thru-hull transducer features high-definition mid-band CHIRP sonar that clearly defines fish targets and structures down to 800’ in saltwater and 1,200’ in freshwater.

Broad Frequency Range

Use the perfect frequency for the waters you’re fishing. Covering the medium frequency range, this transducer pulses from 85–165 kHz, displaying a wide coverage area, crisp fish arches, and accurate depth readings.

Optimum Ping Sensitivity

Offering excellent sonar sensitivity, low noise, high resolution, and good separation of targets, this robust transducer makes it easier than ever to distinguish fish and structure on your compatible chartplotter display.

Thru-Hull Installation

A durable bronze housing and stem offer straightforward thru-hull flush mounting for minimum drag and optimum beam orientation for clear sonar returns.

Auto-ID Technology

Enjoy simple plug-and-play operation with Garmin auto-identification technology — which enables the sonar to automatically configure itself to the transducer being used.

Fits Various Hull Types

Configurable for a wide variety of boat hull materials, including fiberglass, composite, and wood, the transducer is available in a range of tilt versions to accommodate deadrise angles of 0–20° without a fairing block.

Great for school trips and camping
Color: Sunburst Orange, Style: Everyday 3 Season 50-80° F, Color: Sunburst Orange, Style: Everyday 3 Season 50-80° F
My daughter went on a school camp trip and needed a sleeping bag, so I decided to get this one. I chose the adult size instead of the kids’ version so we can use it in the future too. It turned out to be a great choice — it’s roomy and comfortable, and even I fit inside easily. The material feels soft and pleasant to the touch, and the zipper works smoothly without getting stuck. It keeps you warm at night but doesn’t feel too hot, which is perfect for cool-weather camping. I did notice that along the edges there’s a section without insulation for quite a bit of distance — not a big issue, but something to be aware of. I tried to show this part in my video. The color is bright and cheerful, exactly as shown in the pictures. Overall, I’m very happy with this purchase — it’s lightweight, cozy, and easy to use. The only challenge is rolling it up and fitting it back into the carrying bag. Even for me, it took some effort since the sleeping bag is quite bulky. The material seems sturdy and well-made, but we’ve only used it once, so time will tell about its durability. Maybe the manufacturer could improve that part in the future. Still, it’s a great option for school trips, camping, and sleepovers.

Warm, comfortable, and great value for the price
Color: Ocean Blue, Style: Everyday 3 Season 50-80° F
I bought this sleeping bag for my son on a recent camping trip, and it performed surprisingly well. It warms up quickly once you’re inside, and the material feels soft and comfortable against the skin. The zipper runs smoothly and doesn’t get stuck easily, which is a big plus. It’s lightweight and packs down small, so it’s easy to carry and doesn’t take much space in his backpack. However, It’s not warm enough for very cold nights below the temperature rating, so if you’re camping in winter, you may need an extra blanket or liner. Overall, for the price, this sleeping bag is an excellent buy—comfortable, warm, and very practical. I would like to give five stars.

I’m very impressed with this sleeping bag! It’s incredibly comfortable, warm, and lightweight, making it perfect for camping trips and sleepovers. The material feels soft on the inside but durable on the outside, and the zipper works smoothly without snagging. It kept me warm throughout the night without feeling too heavy, and it rolls up easily for storage and travel. Overall, it’s great quality for the price, and I would definitely recommend it to anyone looking for a reliable and cozy sleeping bag.

Perfect for Sleepovers
Color: Forest Green, Style: Everyday 3 Season 50-80° F
We purchased two of these for our grandkids (ages 6 and 8) to use while they visited for 3 days. It was “indoor camping” and they worked perfectly. Lightweight construction made them comfortable in 70+ degrees, and the way the manufacturer uses multiple pockets of insulation keeps it from bunching up, while remaining super soft and comfortable. Clean on a gentle cycle and they will last a long time… a great value for the price!
