Introduction to the Garrett Sea Hunter
The Garrett Sea Hunter stands out as one of the most reliable pulse induction metal detectors for underwater and beach hunting. This detector was specifically engineered to handle the challenges of saltwater environments where many VLF detectors struggle. With its waterproof design allowing submersion up to 200 feet (60 meters), the Sea Hunter gives treasure hunters the freedom to search in conditions that would damage conventional detectors.
Key Features and Specifications
The Sea Hunter operates on a pulse induction (PI) system, which makes it immune to saltwater mineralization that typically causes false signals in VLF detectors. The detector features a 10.5-inch PROformance submersible search coil that provides excellent depth and ground coverage. With adjustable discrimination and threshold controls, users can fine-tune their hunting experience based on target preferences.
The control housing is fully waterproof and features a submersible headphone jack for underwater use. The detector weighs approximately 5.3 pounds, making it manageable for extended hunting sessions. Its battery life runs for about 10-15 hours on a set of eight AA batteries, which is impressive for a PI machine.
Performance in Different Environments
In saltwater beaches, the Sea Hunter truly shines. Unlike VLF detectors that struggle with the highly conductive salt water, this PI machine ignores mineralization and focuses on metal targets. Users consistently report finding coins, jewelry, and relics at impressive depths in wet sand conditions where other detectors produce constant chatter.
The detector performs exceptionally well in black sand areas, which are notorious for causing problems with standard detectors. The Sea Hunter’s pulse technology allows hunters to work these challenging areas effectively, often uncovering treasures that others have missed.
Tips for Using the Sea Hunter
For optimal performance, start with the sensitivity set to about 75% and adjust based on conditions. In highly mineralized areas, you may need to reduce sensitivity to maintain stability. The threshold control should be set just audible to help identify faint targets.
When beach hunting, focus on the towel line and areas where people typically congregate. The Sea Hunter’s depth capability allows you to search deeper than many other detectors, so don’t be afraid to overlap your sweeps for thorough coverage.
For underwater hunting, move slowly and maintain consistent coil height above the seabed. The detector’s audio response changes noticeably when passing over targets, so practice listening for these subtle differences in various conditions.
Comparing to Other Models
The Sea Hunter competes directly with models like the Fisher CZ-21 and Minelab Excalibur II. While the Excalibur offers multiple frequency options and wireless headphones, the Sea Hunter provides similar performance at a more accessible price point. The Fisher CZ-21 offers comparable features but with a slightly different search coil design.
For those considering alternatives, the Garrett AT Pro can handle some wet sand conditions but isn’t fully submersible like the Sea Hunter. The Sea Hunter’s dedicated pulse induction design makes it superior for pure saltwater hunting.
Maintenance and Care
After each saltwater use, thoroughly rinse the detector with fresh water to prevent corrosion. Pay special attention to the coil connection and headphone jack. Store the detector in a cool, dry place when not in use, and remove batteries if storing for extended periods.
The search coil should be inspected regularly for cracks or damage to the waterproof seal. While the Sea Hunter is built to withstand harsh conditions, proper maintenance ensures years of reliable service.
Accessories and Upgrades
Consider investing in a quality pair of waterproof headphones designed for the Sea Hunter’s connector type. Garrett offers specific submersible headphones that provide excellent audio quality underwater. A sturdy sand scoop is essential for beach hunting, with stainless steel models offering the best durability.
For those wanting extended coverage, Garrett offers larger search coils as accessories, though the stock 10.5-inch coil provides an excellent balance of depth and maneuverability for most hunting situations.
Who Should Buy the Sea Hunter?
The Sea Hunter is ideal for dedicated beach and water hunters who frequently encounter saltwater conditions. It’s particularly valuable for those who have struggled with false signals from other detectors in wet sand or black sand areas. The detector suits both beginners and experienced hunters, though its specialized nature means it may be overkill for those who primarily hunt inland sites.
Common Questions
Many users ask about depth capabilities. In optimal conditions, the Sea Hunter can detect coin-sized objects at depths exceeding 12 inches in saltwater environments. The actual depth will vary based on target size, orientation, and soil conditions.
Another frequent question concerns discrimination capabilities. While the Sea Hunter offers discrimination, pulse induction detectors generally don’t provide the same target identification as VLF models. The discrimination is best used to filter out large iron objects rather than identifying specific coin types.
Conclusion
The Garrett Sea Hunter remains a top choice for serious water hunters and beach enthusiasts. Its pulse induction technology, waterproof construction, and reliable performance make it a valuable tool for finding treasures in challenging saltwater environments. While it requires an investment, the Sea Hunter’s specialized capabilities justify the cost for those who frequently hunt in these conditions. With proper care and technique, this detector can provide years of successful hunting in environments where other detectors simply cannot perform.
