Vexilar Deptherm Model 104 Water Temperature and Depth Indicator

Deptherm

The fishing odds are on your side every time you go out with a Deptherm, model 104, for two simple but important reasons. It tells you quickly and accurately what temperatures are below your boat and it also tells you how deep these temperature ranges go. Thus, if you have the temperature chart, you quickly know whether you're fishing in a spot where the fish are most apt to be. If your Deptherm shows the water too cold or too warm for the species you're after, you can quickly move just as the fish do. You won't be wasting the day in the wrong place. Deptherm works like this: dropped on a line, growing pressure forces water into the tube as the instrument descends. The volume of water trapped in the tube serves as a depth measurement column and is read off the side of the tube calibrated in feet. The thermometer on the other side assures close temperature readings if the instrument is left down for 30 seconds.

General Application:

Attach the Deptherm to line and let sink to bottom or any intermediate depth. Hold there for 30 seconds and return to surface. Read depth on the calibrated side at the top of the water column and temperature off the temperature plate. Invert instruments; press valve to release water. Shake until all water is out before using again. Downrigger Application - Clip the Deptherm Model 104 to your downrigger ball for monitoring water temperature and depth at the downrigger. When raising the ball for re-rigging, check the temperature and depth. Temperature readings on the Deptherm will not change while ball is being raised due to a delayed reaction (1 to 2 minutes).

Features:

• Tells you how deep it goes


• Seeks out the correct temperature


• Helps you stay in the preferred range where fish are most apt to be feeding

Specifications:

• Length: 5"

The Vexilar Deptherm Model 104 is an essential tool for serious anglers seeking to optimize their fishing success. This device provides quick and accurate readings of water temperature and depth, helping you identify the most productive fishing spots based on temperature ranges and depth profiles. By attaching the Deptherm to your line and allowing it to sink to your target depth, you can monitor the exact conditions where fish are most likely to be feeding. Its calibrated water column indicates depth in feet, while the thermometer ensures precise temperature readings after just 30 seconds of immersion, enabling swift decision-making on the water. Whether used at the bottom or at intermediate depths, the Deptherm allows you to adapt your fishing strategy in real time, reducing wasted effort and increasing your catch potential. When used with a downrigger, simply clip the device to your ball to monitor water conditions at specific depths during re-rigging, with temperature readings remaining stable during retrieval due to a slight delay in response. The device's straightforward operation and reliable measurements make it a vital addition to any fishing arsenal. By staying within optimal temperature ranges, you can target fish more effectively and improve your overall fishing experience. The compact 5-inch design ensures ease of use without adding significant weight or bulk to your gear, making it perfect for various fishing environments.

Features:

• Provides accurate depth measurement in feet

• Seeks out and displays water temperature

• Assists in maintaining optimal feeding temperature ranges for fish
