Pros & Cons of Using Side Imaging Depth Finders

Pros & Cons of Using Side Imaging Depth Finders
Fishing has changed with the advent of electronics and sophisticated consumer products such as depth and fish finders. Various forms of the devices are available, including side-imaging depth finders. Side-imaging depth finders work with sonar and allow anglers a 180 degree view of what is underneath them. Using these devices has many benefits and a few disadvantages.

Pros

Side-imaging depth finders allow anglers to see a full 180 degree range under the boats, of depths to 1,500 feet, depending on brand and model used. Modern side-imaging depth finders have large, interactive touch screens, allowing you to point and click to save waypoints and mark where there are schools of fish or underwater obstacles. Side-image depth finders provide a more accurate and better image of the underwater scene beneath the boat vs. traditional finders that give displays of only what is under the boat.

Users from independent fishing forums such as The Hull Truth website report having 180 degree range of view as beneficial when going for big catches. Users on waters with depths of as low as 20 feet to as far as 1,000 feet talk of positive results with a side-image depth finder.

Cons

Side-image depth finder technology comes at a cost. These depth-finding devices are more expensive than the traditional models, in some cases by more than $1,000. For example, the HDS-7 Multifunction Fishfinder/Chartplotter costs around $1,000. It provides high-definition viewing with a high sensitivity GPS antenna.

However, to get accurate imaging from many side-image depth finders, users need to learn the side-imaging display as well as the vertical up-and-down readings. Using this three-dimensional imaging has a steep learning curve, requiring dedication in getting to know the device, according to user reports from independent fishing forums such as The Hull Truth website.

Hit Markers

Users at Crappie.com write having success with the Humminbird side-image fish finders Hit Mark function. Hitting the "Hit Mark" button drops an electronic breadcrumb via the depth finder's GPS capabilities, allowing you to return to the spot should you drift or move from prime fishing locations. Users say for the Hit Mark to be effective, you need to be moving at a speed of 3 to 5 miles per hour. After dropping a Hit Mark location, type in the name of what you call it to personalize your fishing locations and maps made with the side-image depth and fish finder.
